hi everyone I'm good morning hopefully
this was designed to be kind of a
natural progression from learning about
3d scanning and how to obtain models -
now what do you do with the models and
so the two kind of techniques I'm going
to talk about our 3d printing where you
can take that digital 3d model and
create a physical copy of it and
augmented reality where you can put as
arty you've already seen this with the
hololens you can put the 3d model over
the the real world so kind of an outline
of how this sections going to go can
talk about what is 3d printing I'm
talking about how you can use it in your
research and teaching or talk about how
to 3d print I'm kind of hoping that this
is both a kind of a broad overview kind
of get a bird's eye of what can you do
with these technologies but also since
this is this is a workshop I want to get
into the weeds so that when you leave if
you don't have experience with these
technologies you'll know where to start
and what software to use and where to go
if you've already used the technologies
please you know jump in always ask
questions but also share your own
experiences if you use 3d printing or
augmented reality after we talk about
how to 3d print we'll go into a our talk
about what uses you know especially here
at UF saying in research and and
teaching and then we're going to do kind
of a hands-on demo using Erasmo which is
now as of a few months ago called on HP
reveal so hopefully you've had a chance
to install that on a smartphone or a
tablet if you want to follow along i'm
otherwise i think i figure out how to
Mir my phone to the projection system so
you can at least see what I'm saying
otherwise a our is kind of boring okay
what is 3d printing um it is a form of
additive manufacturing so this is the
concept that you can make physical
models layer by layer by layer we're
going to talk about a variety of
technologies and and it uses a variety
of materials so it's not just the
plastic which is what you're gonna see
um there's also metal and nylon and
multi rasa
and it seems like every month or two
there's new materials coming out that
you can use in 3d so here's a here's a
schematic that shows right now kind of
the the landscape of 3d printing it's
it's really all over the place we have
sheet lamination where you can actually
make 3d models out of pieces of paper
glued together mixed Tyrael extrusion
where you're heating up something and
you're you're squirting it out
we have powder well I'm going to go into
these in a bit but you can see that
there's a large variety of different
types of technology for making these
these 3d models so the most common kind
that you're gonna see in magazines you
can see in TV probably you might have
one in your office we have them in the
library I mean you can actually down in
Australia they're selling it at all
these I'm around Christmas time so these
are they're known as FFF fused filament
fabrication you might also call them
hear them called FDM fused deposition
modeling that's actually a trademarked
term by stratasys so we like to use FFF
this is the way the technology works is
I would basically describe it as a
robotic glue gun where you have your
your spool of filament now come over
here to this is one of our library
printers we have our spool kind of
thread goes in the printer it goes down
here we have some cooling fans because
it's gonna get very hot right at the
bottom of the nozzle it gets - this is
printing at around 210 Celsius so that's
in the mid 400s for Fahrenheit
so it gets very hot but you don't want
you don't want that heat creeping up the
tube because then a clog so we have a
bunch of a fans right there to keep it
cool and then we have this build plate
and I am going to try to start it and
this is a fairly slow process
all right so I'm printing out probably
can't see it quite there but it's a tiny
octopus just for a demo they tend to
print really well
we have blue painters tape here on the
bed this is a cool bed some of the
printers also have heated beds to
facilitate adhesion okay so you can see
it's starting to heat up and in a few
minutes it's gonna kind of beep at us
and it's gonna start printing so we'll
let that go for a bit I'm another type
of Technology is stereo lithography and
this is known as SLA and the way it
works is that you have is not the video
um you have a vat of liquid rosin and
you have a laser and a laser shines up
and it cures the the liquid rosin and it
pulls it out layer by layer by layer and
so again it is building up a 3d model
it's similar in its the same type of 3d
model that you give the software but of
course it has being made out of rosin
cured rosin it has different material
properties I mean it tends to be very
high resolution so unlike the the
plastic FFF style printers down here in
the bottom you can see this is an
example that I would say this is
actually a very badly printed so not
perhaps the most accurate but this would
be an FFF style where you have kind of
plastic strings that's coming out and
this would be an example from an SLA
type of printer so SLA that they're very
popular museums for people who need to
make replicas very small very finely
detailed objects so people who are are
casting say miniatures for games they
like this type of a 3d printer the most
popular ones are made by formlabs
they're up to the form to I think I
might have to form three out soon and
they run approximately three thousand
dollars this is a really messy type of
3d process
because you're they've tried to make a
fairly self-contained but when you take
out the model its dripping with rosin
you want to have a sink nearby so for
those reasons we don't have them in the
library all right another type of
technology is known as SLS selective
laser sintering so this is where you
have a powder and it could be metallic
and nylon so different types of
materials but it's a powder base and it
uses a laser to just again it's fairly
slow but you're centering you're
hardening this powder layer by layer by
layer and you're building it up one of
the the major advantages of this
technique is that this model is is still
encased in its powder and the powder
access support material so supports this
is one of the limitations of 3d printing
with this type of a printer you know
it's laying out this layer of plastic
and it has to have a base to to lay out
lay out each layer on I'm so imagine
you're printing on a tree and you have a
branch without support material holding
it up the printer would shoot out a
string of plastic and come back now if
it's a short distance it might be okay
because the plastic does does cool very
quickly I'm at hardens I would say
almost not quite instantaneously but
very close but you're still gonna have
some droop and maybe the droop isn't so
bad so you can bill the next layer and
the next layer that's okay but if it
droops too much or it just doesn't
really you know form that that solid
solid branch you know it's going to fall
and your model is going to be worthless
because there's really no way to recover
at that point and so the way we get
around this with this type of printers
is that we have support material and
that is is beta the same the same type
of plastic but it's designed it's kind
of this waffling material that the
software adds and it builds up from the
build plate upward and so when it gets
to that branch there's already something
there it can build the branch having fun
trouble and then you can remove it with
say pliers
and so you can see advantage of having
something like this SLS where you can
just take an airgun and you can blow off
the powder and you release this pristine
model that's a real advantage all right
a different yeah a fourth type of 3d
printing this is a poly jet so in this
we you have a liquid liquid photo
polymer and it's at the same time it's
it's spraying out very minut particles
of this liquid it has a laser and it's
it's hardening it and so again it's it's
doing the layers so it's somewhat
similar to the SLA that you have a
liquid rosin but here you're actually
spraying it out and you're hurting at
the same time these printers they're
very expensive and hundreds of thousands
but we do have some of them on campus
that are use accessible to the UF
community and they're capable of
printing multiple materials and multiple
colors and so if you're trying to create
a replica you know and you you want it
to be you look as realistic as possible
rather than having to paint plastic you
know this is a great solution for both
high resolution and making it making it
look accurate so in the video you can
see it's it's spraying out these it's
liquid and it's Harding and
instantaneously and it's building it up
these are very strong models very high
resolution and very expensive okay so
going back to our FFF style a 3d printer
how many people have have used 3d
printing on campus okay it was great it
was a good number how many people have
used something other than the FFF style
okay so pretty much everyone's
experiences with this type and that
makes sense because these are very
affordable at these this point you know
I mentioned that they're selling about
all these in Australia
I saw one for sale and I'm not saying it
was a good 3d printer but it was $187
which is getting very you know very
inexpensive up to the ones that we have
in the library they're around five
thousand so that's that's I would say
kind of range if you get above five
thousand you're probably gonna want to
look at other types of technologies that
are perhaps you know faster or have
higher resolution but looking in the in
the price range what what we're
discovering is that spending more on
printers that doesn't necessarily get
you a faster or a better better printer
what it probably does get you is that
it's a larger build volume it it might
be more reliable more accurate so you it
was machined better you don't have to
tinker with it so much when you get down
to the the printers that cost several
hundred dollars they might be in kit
form so you're having to put them
together yourself you probably start to
learn your printer really well and
replacing parts or upgrades and so you
know you have your your plug-and-play
ones or you don't to think about it
versus the ones that you can care and so
you have to think about you know what
are you willing to do but we have had
ones that are well actually so these
Printrbot plays these are around three
hundred dollars and we are finding that
assuming it's all set up well and
calibrated well that the models look
just as good as they do on our three to
five thousand dollar 3d printers they
just take a little while to produce and
they're smaller so talking about the
filament in these type of printers and
there's two major types abs and PLA
there's actually other types of a
filament now that are becoming more more
popular there's ptg there's hips
there's dissolvable filament like PVA
polyvinyl alcohol which if you think
about you know the need for support
material if you can have a printer that
has dual extruders so that you have one
type of material in one and your
dissolvable support material on the
other then if you can dissolve support
materials you've taken away kind of one
of the main main issues with this type
of
technology we're having to clean off the
model becomes an issue but going back to
kind of the traditional two types ABS
versus PLA everyone probably here is
familiar with ABS because it's the
plastic that's used in Legos so it has
tons have a glassy exterior it's very
strong it's also petroleum-based so when
we talk about printers and we talk about
emissions coming from the printer I'm
being petroleum-based it's tends to
produce fumes that are very noxious and
unless you have extremely good
ventilation you know ideally in a the
base came off Oh drat all right I'm
gonna stop it because I don't want to
debug this in front of you okay hunters
also fail a lot especially when you're
doing a live demo um so so talk about
the noxious fumes
you know emissions are an issue with 3d
printing I recommend you always having
adequate ventilation I would say it was
a BS you want to stay far away from it
PLA is the sense for poly lactic acid
this is derived from a plant starch so
people consider it green although you
know it so does it is biodegradable
although it's over many many many years
is also fair your the strength is is
fairly good maybe not quite as strong as
abs but unless you're putting lots of
stretch and pressure pressure on the
models you might not really need those
properties um
it extrudes at a slightly lower
temperature so your printer can you
don't have maybe have to have quite such
a high-end printer to do like you do for
abs and you can sand both of them but
abs has the ability to be dissolved in
acetone and people like that because you
can create what's called an acetone
vapor wash where you can put your model
either you can dip it in acetone or you
can put it in something where there's a
stone fumes and it tends to what I'll do
is it'll kind of I'll use the word melt
but it'll it'll soften the exterior of
your model
and so you know instead of having a
model with you you can see the lines
perhaps from the layers now you have a
glossy model that looks like you know it
came from a mold ejection system PLA you
can't do that it doesn't dissolve in I'm
I know there's chemicals that it does
it's all been but they're they're not
ones that you would have access to so
you can stand it you can paint it with a
you know an epoxy but so that's that's
kind of one trade-off the other thing
about PLA is that you have to be aware
of is that it does because it extrudes
it'll lower slightly over temperature at
around like 100 120 degrees Fahrenheit
it starts to soften so you know for most
applications and that's not a big issue
but if say you're printing out something
to hold your phone in your car in the
hot Florida summers that's an issue
sometimes it'll start to droop so these
are all properties that you have to
think of when you're 3d printing so why
would you why do you want to print what
are some what were some reasons you know
we hear the criticism about 3d printing
is that it's only for producing trinkets
and you know obviously we have some
trinkets up here after this you know
during lunch I hope you have a chance to
come up and look at the models but there
are real
you know academic teaching research real
reasons to to use 3d printing and we'll
kind of go through your I've categorized
them into visualization sharing
preservation and then creation so 3d
printing is is fabulous for for
visualizing especially things that are
difficult to to comprehend otherwise so
for example and Natasha vidiq and she is
she's with the museum she was a grad
student here I'm not sure if she's
graduated at this point this was several
years ago but she was creating lesson
plans to help fourth graders understand
differences in scales of objects and
she printed out a virus
tardigrades which are you know minut um
loud lice and I'm not going to try not
that
um and what she did is that you
especially with the virus is that she
printed it out at different scales until
you see this upper one that's actually
that's this virus I think multiplied by
a thousand and she had to pronounce
pieces because it was so large but you
she probably heard of this to the the
class so they could they could see the
differences in scale and kind of get a
sense of how small things actually are
we're seeing it more and more in the
medical fields allowing surgeons to
visualize to even practice the surgery
before they go and actually do it on
people this was an interesting case
these were this was back in 2016 in
Houston at the Texas Children's Hospital
this was a conjoined twins and you can
see this is they had a CT scan and they
they 3d printed the organs and the ribs
and you can see this was a very very
complicated situation and of course you
know they this this whole process took
months of preparing for the surgery but
by by printing it out by actually seeing
how things were and they were able to
plant out and the surgery was a success
that you want to have you want to make
sure that your 3d printer is very
accurate it's you know producing the
princess you know at a high enough
quality well we are actually contacted
this was a couple years ago by the the
vet school and they were they had a 3d
model of a tumor and it was a dog and
they were gonna do surgery in the next
couple days and they wouldn't know if we
could print it for them so that they
could look at the tumor and you know
think you better hurt well we have nicer
printers in this but you know I had to
decline because and send them over I
referred them to the fab lab because I
didn't want to take the chance that our
3d model just wouldn't quite be accurate
and they'd go to do surgery on these
dogs but I think this is a really
excellent application I'm something else
that we've been working on and
library is and this is over several
years we've been printing out models for
researchers in SC zoology and they are
developing a training device and I've
only seen pieces so I haven't seen it in
the full all together but it's going to
be a training device to allow simulation
for giving injections through the
ribcage so again something that you want
people to practice on before they
actually do the real thing I'm also
talking about concepts that are
difficult to comprehend otherwise
mathematics so you can print out
functions here's a Klein bottle up there
in blue this is a Golgi apparatus so
this was about seven layers and this was
printed out by a biology professor here
at UF and he wanted to you be able to
pass this out to his students so they
could see how it all I looked and I have
to say that that was a quite a challenge
to print we have some one specific
colors we've done we've printed human
proteins so this was actually when we
started our service back in this
would've been about early 2014 this was
one of our our guinea pigs I'm a
researcher in who is starting to
understand how human proteins interact
and he thought that if he could hold
them in his hands and you know
physically manipulate them and try to
get them together he that would give him
insight and so he you know his whole
research lab came to library and we all
you know watched our brand-new printer
you're printing out these human proteins
and they were so excited that he went
back he purchased his own 3d printer and
we really haven't seen him since
although we've seen other people come
for mr. apartment saying you know hey
Brian stuff is over to you and you know
let's and that's kind of the the pathway
to getting into 3d moving on beyond
visualization talking about preservation
and sharing this is something I find
really exciting because there's so many
you know fragile and rare things in the
world that you know especially in
research and teaching that you want you
want to have access to you want your
students to be able to hold and
experience but for whatever reason they
you know they won't be able to otherwise
so now with with 3d printing if you can
retain the 3d model you can print it out
or you can you look at it digitally and
you can you can see what it's like
without having to go to the object or to
acquire it many museums now are are
scanning in their specimens their
objects and making them available these
are from the Sony ins x3d I think
website um so it's your website they're
freely available you can download some
of the models and you can not all of
them are suitable for printing like
obviously Amelia Earhart's soup probably
won't do so well in the printer but you
could try to print the bust
I'm paleo teacher org this is a NSF
funded project with the Florida Museum
of Natural History and I think it's a
partnership with Duke University and
they 3d scanned a full set of Megalodon
teeth and also a paler Paleolithic
equine teeth and what they they did they
scanned it and they provided those
models both digitally and 3d printing so
there was a whole summer a couple years
ago where you just printed out shark
teeth and I have one of those here of
course you know kids see this and they
instantly know what this is and this is
real size which you know it's pretty
amazing and then along with these these
models or the files um if they have
access to a 3d printer and they came
also within lesson plans and so you know
for example with the equine teeth
students could measure the size they
could look at you know how the tooth the
wear on the tooth and by making
different measurements that would tell
them about the the climate at the time
because you could tell you know what
were the what were the horse is eating
when it was a grass were they showing on
branches because that would have
different wear on the teeth and then
that once you know what they're what
they were eating that would give you a
sense of what the vegetation was like
and that would tell you about the the
temperatures at the time so it's kind of
a proxy so looking at how the climate
has changed
and then of course if you make
measurements on shark teeth and then it
can tell you the age of the shark I know
there's other things involved but very
popular and actually I was Adam
Gainesville high school about a year or
so ago and there had one of the teeth
there and I went to see Jen you know we
printed that out so I know that they're
being used at you know K through 12
schools not only in Florida but also
across the United States another this
was about maybe two years ago how evil
heard about this the homeowner lady
discovery so a few this was very
exciting down deep in the the base of a
cavern or a cave system in South Africa
they discovered just a large amount of
fragments of bones and it was very
difficult to traverse well they went in
and they actually 3d scanned the entire
site so they have that preserved before
they remove some of the fragments and
then when they came out actually in the
field they 3d scanned and they made
these these models available it's a
website called Morpho source and it's
hosted by Duke and you can go there
after this and you can download the
scans some of their in CT scans some of
them have been converted to the type of
file format that you need for the 3d
printer so we did this when they were
available this is a picture showing the
printing of progress so you can see that
we had a lot of support material
printing halfway and then one of my
colleagues Dan Robertson he's African
Studies librarian and he he painted
these and that was kind of his first
experience painting plastic models but
he used he went to I think was do ants
and acrylic paint and sponges and they
turned out I would say very they look
very realistic and so those have been
passing around and and as I this isn't
my field but as I understand it a lot of
times you know there's more researchers
than there are our bones to actually
analyze and so for the first time
these were made very quickly publicly
available and the paper was also open
access and so it's a case where you're
making you know these researchers
decided that it was very important for
the entire basically the entire world to
have access to their research
immediately rather than holding on kind
of hoarding it and making it difficult
to access and they've continued to
release you know more 3d models and so
it's it's really quite something really
and then moving into creating with 3d
which of course is what people you know
mostly think about with 3d printing this
is a student organization called grip
this is at UF and the library sponsored
them over the last few years and they
they design and 3d print prosthetics for
children and teenagers with upper limb
differences mostly their their local
youth but they've also worked with with
children I know there was there was a
child in Arizona they've also worked
with a child down in South America I
forget exactly which country but they
have these different projects and it
started off with 3d printing kind of
this basic hand it sort of works off
puppetry where you bend your wrist and
it curls the fingers and and that was
great and all but then they just they
realized after working closely with the
children and this is always in
partnership with a child the child gets
us you know they talk about what they
they want their hand to look like what
color they want what designs they want
they realized that you know the five
finger hand might not really be what a
child once they might what they're
moving towards is kind of a modular so
depending on the task that they're doing
they attach a different device and it
lets them let's see I don't have the
picture here this is one of their
detachable ones so there's the five hand
but there's also an attachment that lets
let's this boy I'm kayak also they have
a marshmallow shooter they're developing
all sorts of different and that's driven
by by the child or the teenager you know
I want to be able to do this and then
the undergrads here they brainstorm how
can they work
how can they make this work and it's
it's not just with the undergrads
they're not just engineering majors
there's also majors coming from art
psychology and so it's really an
interdisciplinary I'm group and this
year they've actually doubled in size
over 200 students attended the first
meeting and they have ten different
projects going on so it's a really
really exciting group and here's another
case was several years ago this is an
undergrad and he wanted to study how
Predators go after baby go gopher
tortoises and gopher tortoises are
endangered and his his plan was he
wanted to have a model of this and he
wanted to put it in a city area and then
he wanted to film how the Predators go
after it he only had one specimen though
and was preserved in alcohol and so he
needed to you know figure out how could
he help me make all these models and you
want to be as accurate as possible and
so you probably heard a little earlier
there was an app a while ago called 1 2
3 D catch that used photogrammetry
taking images of something and then
converting into a model that's what
Gabriel used turn on the video here and
so he came to the library and you know
he's a poor undergrad he didn't have the
funds to do something expensive but for
just a few dollars he could print out
this model what he discovered was that
the model being out of plastic was too
hard to record the predator bite marks
and so he ended up taking the model
turning into a mold and then I'm
creating lots of different you know baby
tortoises out of plaster and then he
painted them he scented them and he
buried them and this is a study area
down near the Cape so apparently he
fooled a lot of the Predators we have a
raccoon come by he end up winning award
for this research he went down to Disney
and presented at something he also had a
night camera no no that's a
these raccoons and so this would this is
research that we've been very difficult
to do without having 3d scanning and 3d
modeling and printing they're trying to
get at it a second we have a bear I like
to possum I think one of these the
Predators actually does get the there it
is
open there's the bear
something he was able to retrieve it and
look at the bite marks and yep it's
buried so these are the kind of projects
that we get really excited about in a
library you know students seeing
students enabled to to create these you
know the prosthetics and do their
research that they wouldn't be able to
do otherwise there it is on the printer
okay so now that I've inspired you um
how do you 3d print so the first thing
you have to do is you have to have a 3d
model you know and you've already heard
a couple hours now how you can scan in
an actual object and create a model so
that's one of the ways but there's also
websites that you can download 3d models
that are free to use we mentioned the
Smithsonian website and I'll talk about
a few others in a second and then the
third way is that you can you can make
your own model using modeling software
but first this should look familiar
talk about file formats now for 3d files
there's all different types of formats
and for 3d printing an STL file that's
the most common some there's different
different words people say for STL sarah
lithographic is is one it's a grid and
the grid is made up of triangles that
hopefully are not missing and so this is
one of the things I want to point out is
that if you have a model file that has
errors in your grid where you're missing
triangles that basically renders it you
can't print it it's not a printable say
it's in it it's not manifold it's not
watertight so it's the concept that for
3d printing what we care about is the
surface we don't care about what's
inside the model it's not a CT scan
so if you think about the model as being
an egg you know the shell has to be has
to be whole it can't have any cracks I
can't have any holes it needs to be
watertight there is software that you
can use to repair models so if you find
a model that you really like but it has
you know gaps in the grid and you if
you're scanning you're always going to
have to clean
I mean you're never going to have a
perfect 3d model but there is so much
lab was mentioned meshmixer
by Autodesk that's another solution
there's other other software but you can
put your model in and you can heal it
you can clean it off and then hopefully
you can 3d print it so for downloading
kind of one of the the major ones at
this point is called Thingiverse like
universe but with things there's
probably over a million models there at
this point and hopefully there's
instructions and there's photos if say
you download a model and you print out
you have the ability to upload your
photo to it and make comments you know
this was a good model this is a bad
model and it's important to look at
those because Thingiverse is like
wikipedia where anyone can can upload a
model and you don't know if it was
someone very skilled or my
eight-year-old doing it and you can and
you know which one you want to print and
so you've never printed before you don't
want to select a model that has no
actual photographs and you have to look
at it really closely because people are
getting very good at creating
computer-generated images where it looks
realistic but it's actually not you want
to make sure that someone has printed
out before you spend your money and your
time your effort to print out your own
version you imagine is another one
there's Smithsonian's x3d there's my
mini factory there's a there's a large
number of repositories out there and
there are overlap and models between the
two so you know if you're looking for
something very specific take a look but
I would start probably with Thingiverse
what you want to do though is make sure
that the STL file that's what you
download you can do also OBJ's but STL
for the 3d printers that's that's the
easiest and just remember that if you do
find something you like you can clean it
up with mesh lab meshmixer there's
actually an online tool Microsoft has a
partnership or they own net fab and it's
a website where it's free and you upload
the model and it tries to
fix it and then you download it and it
actually does a fairly good job most the
time you always want to take a look at
it to make sure it hasn't just covered
up something that's very important but
if you just have a small few you know a
few holes in your mesh it does work
fairly well it's free it's fast ok the
second one 3d scanning you've already
heard quite a bit about that I do want
to mention that with the structure
scanners that they showed you we
circulate them in Marsten so we have
them for checkout and they are free to
use you take them out library for three
days and we also or if you need longer
you come talk to me we also check out
iPads so you can walk out library with a
scanning solution right there you can go
there today and get them now and and
scan we also have a 3d laser scanner so
we have a next engine the Wonder Marston
right now is down we're kind of moving
it around trying to find a good spot for
it but the architecture and fine arts
library has one as does the Health
Science Center library so these are see
it's this picture up there it's about
the size of a cereal box and it has a
turntable and is attached to a
workstation and you can put your object
there and it produces a very high
resolution and um scans it does take
some work to clean it up so this isn't
you know a fast scan you got your model
you know the structure is fairly fast
the next engine is going to take you at
a time but those are free to use you can
have their own walk-up basis so you
don't to make a reservation you just go
in and ask where the printer or the
scanner is and you can use it for as
long as you need to and so then the
third way is that you can create your
own model using modeling software there
are many different kinds of software out
there
our engineers they they're required to
learn SolidWorks
so that's if you're making something
that needs to be very precise and
geometrical SolidWorks it's kind of
Engineers choice for software Tinkercad
is
this is free it's a another Autodesk
product it's web-based it looks very
childish but it's very easy to learn and
it produces models that do really well
in the printer it's also very fast to
use and so you can even import models
into Tinkercad
you can modify them you can slice things
off and you can export them for printing
you can add text to it which for a lot
of people that's what they want to do is
add you know words to whatever model
they have and you can export it and
that's ready for printing so if I need
to do something that's very simple like
cutting things off or merging models
together I'll just put it into Tinkercad
because it's so fast and then if we talk
about more organic shapes we have
blender
there's Maya there's 3ds max so
definitely software that has a bit of a
steeper learning curve but you can
produce some really amazing models I do
want to mention the Sketchup doesn't
export models very well for printing so
STL's maybe some of the new versions
have fixed it but the models that we see
coming out of Sketchup they tend to I
don't know gaps or something about it
makes it very difficult to print so I
would just advise using another product
we also have if you're interested in
SolidWorks but you don't want to figure
out the license there is a free academic
license for students but take a look at
on shape it's it's a web base and it's
free and it's it's created by people who
used to work at SolidWorks so it has
some of the same capability but just
remember that not all 3d modeling
software is designed for 3d printing
that just because you have a 3d
representation of a model doesn't mean
that it's going to do well on the 3d
printer and it might actually work on
one type of 3d printer you're thinking
about those different types of
technology but not work on other types
so you have to think about your model
and use the technology that is best
suited for that
so then what makes a good printable
model this is actually we had an exhibit
recently with um insects and entomology
has been CT scanning some of their
specimens and then printing them out and
so obviously the dragonfly is not actual
replicas but these other ones are made
from CT scans so that was also kind of a
challenge to print out spiders so things
that you you're gonna care about
obviously the design has to be has to be
well done you need to be structurally
sound so say you're printing out a box
we print out lots of boxes I don't know
why the sides of your boxes have to
touch and they have to touch well may
have to overlap they can't just you know
you're modeling when you just get them
to kind of touch a little bit because
when you print them out if they're not
solidly connected they might not be
attached and of course you don't want
any unintended holes you think by the
appearance
you're gonna care about the scale
because this will be a physical object
make sure that things are proportional
and make sure that the walls are thick
enough so I kind of give a rule of thumb
it needs to be at least one millimeter
thick if you're using this type of
printer otherwise there just isn't
really enough plastic to to hold it
together you think about this the
limitations of your printers um you're
gonna have a size a maximum size of the
plate so for the Printrbot play here
it's about four by five and then about
five inches height so that's the largest
model that you can print on that printer
and maybe even with some printers you
don't want to go to the very full extent
the plate because the plate not be fully
level and so it's tilting slightly your
cave your model stays in the center but
if it gets out to the the edge of the
plate some you can see maybe it doesn't
adhere like you saw the octopus pop off
and then you have problems if you need
to print out something that's larger
than what your printer allows then you
can slice it up into different different
portions and then later glue it together
and that's a way to get around it and
that's what you saw with the virus
again make sure that your your features
are at least one millimeter thick that's
kind of a rule of thumb think about the
supports if you need supports maybe
there's a way that you know when you
give us a model for printing or you're
printing out yourself
in the software you can rotate it and
you can decide which way you want it to
print and maybe there's a way that you
can print it that you're gonna minimize
support material and so you want to keep
that in mind
or maybe just by designing it slightly
different you remove the need for
support material because it does take a
while to do support material to remove
it so this is a molecule that was made
by a student chemistry this is what her
research is on she went to give a copy
to her her advisor so this thing was
covered in support material and it took
me about two hours with my pliers and a
couple band-aids to get it all out which
was doable and she was happy to do it on
her own but it was it was work and
there's some things that your imprint
that you're just not gonna be able to
get in and actually removes the support
material here's a case so you might have
you might recognize this and we didn't
actually even plan it out you saw the
digital model of the statue
this was scanned and so we printed it
out and this is a while ago this the
print actually isn't very good but it
had lots of support material in it and
later on you can come down and you can
look at it's kind of the waffling
material that's hanging hanging off and
actually this this Ridge there support
material in there and it's just it's not
gonna be possible to remove so there's
in some cases where you can't remove it
and so you have to think about is that
is this the type of printer that you
want to use for printing out your object
or maybe you want to find a printer that
has the dissolvable support material
and then you want to think about is the
printer material is it appropriate for
what you're using do you need to be
waterproof are you gonna be putting in
your car in Florida in the summer you
know the if you think about the formlabs
the rosin printers the models are
they're just gorgeous you know they're
high-resolution and they're lovely but I
saw one at a museum in New York City and
and it was it's kind of a 3d printing
display and it was out for lots of
people heads had held them and they were
kind of sticky at that point so like
moisture had affected the the model and
I don't know if it was you know sticking
for another reason but it just was kind
of tacky and I don't have experience
with that type of printer but I suspect
there was a way to to preserve it I'm
some sort of material you could paint
over it to keep it from getting like
that but you have to think about you
look at the material properties of you
know the filament for example you know i
mentioned not just abs and PLA but
there's also ptg and nylon and all
different types of material and the
material properties are available online
that you can look at say their tensile
strength and see is that what you need
I'm talking about supports are difficult
to remove and this is I think this is
Hubble telescope so this this material
down here that support material that's
holding up and you can see how how thin
the solar collectors I'm pretty sure
that's what that is and they're so thin
that they're smaller they're thinner
than the actual support material so one
of the things you're gonna see is it's
possible to print it out but when you
remove that support material it breaks
off the actual model and so that would
be a failure also models can just be too
thin the printer is gonna try to print
it out and I mean it does say you know I
can't print this out it does its best we
had a request to print on a feather and
you see this the center is edge on this
was too thin different software thought
I could print it out but it couldn't and
they course wanted to print it up right
because they wanted both sides you know
preserved but we couldn't do that and so
have your model so to get ready for
printing there is software then that's
separate from all the modeling software
there's printer software that takes a 3d
model and they prepare it for printing
so we call this slicer and it slices it
into different you know the different
layers and you tell it the thickness so
most of the printers that we have in the
library they're printing at point two
millimeters so it's very very thin and
that's a single layer so you can even go
down to point one on our printers of
course you know the more expensive
commercial 3d printers will do even
higher resolution you go from point 2 to
point one that doubles the print time
and we so we we even at point two you
have models that will take 36 hours 40
hours so doubling it that's a long time
there's free software for controlling
the printer
sokurah andhra petit a if you end up
using one of our library 3d printers and
I'll talk about that Kyra would be
software that you would download
there's also proprietary software and if
you really into 3d printing I just want
to put a plug out for simplify 3d which
is 149 for 2 licenses but Bar None is
the best printer control software out
there we decided it was worth it so
we're on campus how can you print the
libraries how many people had printed at
the libraries this is great okay well
I'll just go through a few things anyway
so we have 3d services at three of our
branch libraries we actually had four
over here in education but as you know
they're closed right now so when they
reopen hopefully we'll add them to the
list marcin we have the the largest
number of printers so we offer 3d
printing we have our scanner and we're
circulating technology so out of Marston
next to the front flies over an AFA we
have a 3d scanner and then down the
Health Science Center they have several
3d printers and they have a scanner you
can use so depending where you're on
campus there's an option for you and the
way our service workflow goes is that we
have a website 3d print UF Lib dot UofL
de deo right now we have about 10 color
the filament including glow-in-the-dark
and you can go to the website and you
can upload the 3d model to the site and
we then look at it our 3d desk is open
from 9 to 4 you're also welcome to come
in person and we can look at the model
with you and you know talk about whether
or not it's going to be doable for
printing we slice it and we then send
you a quote or if you're in person will
tell you there if for whatever reason
you want to be a certain size or you
want to keep it under a certain dollar
amount you tell us that and we can
resize as necessary our charge is we
charge fifteen cents a gram and you can
you prepay either with a credit card or
a P card and then it goes in the queue
and when it finishes printing we pull it
off we send you an email and you come to
library during our business hours and
you pick it up at the Service Desk so we
try to make it as easy as possible and
as affordable as possible here's some of
our printers here's our new fusion 400
this is our largest actually we just got
a slightly larger one now I think about
it the fusion 400 is 14 inches by 14
inches by 12 and a half now if you print
out something that takes that entire
build volume that is days worth of
printing it's gonna cost a pretty penny
so we've had one person take advantage
of the entire height we have a slightly
smaller fusion f3o six with 12 inches
cubed we did just get an Ulta maker 3
that I think the build plate is slightly
smaller but it's higher I think it's a
16 inch so if you wanted to put on
something that's very tall and skinny um
that would be the way to go and then we
have these Printrbot plays that we are
checking out and the way that works is
we have Oh between 10 to 15 but they
break so it's hard to say how many we
have at a given time but at some point
hopefully we have all 15 in circulation
you can check them out for 3 days this
is free to you so if you want to get
into 3d printing and you
pay anything this is the solution
because we're gonna give you 250 grams
of filament it's white at this point but
I have a secret for you we had you have
a box behind the desk where when these
spools kind of get down to the point
where it's not worth our time with the
bigger jobs we'll take off kind of the
drugs of this and we'll put it in a box
so you come and say you know you have
some orange filament we'll get the box
and we'll give you you know whatever
color you want they come in these
Pelican cases here and wheels so this is
really sturdy and you will it out of the
library I would advise you know not
printing it in your bedroom next to your
bed with the windows closed you know
make sure you have adequate ventilation
at home but you can print for three days
as much as you want if you run out of
fill in you come back to the library and
we'll give you more filament so you can
really print whatever you want
um you do need to have it's heathered to
a computer so unlike say our larger
printers where you can just put an SD
card and it goes you know by itself you
need to have a laptop connected at all
times to run them I'm just kind of a
heads up if you are doing this make sure
that you don't have a screen saver or
your computer go to sleep you know after
an hour or two because that's really
unfortunate it shuts down the printer
and there's no way to recover once it
stops there are a few other options on
campus and then there are online options
for 3d printing so over at an Infiniti
residence hall I'm so just actually
slightly north east of us a few blocks
there's the Fab Lab and they're located
on the first floor and they have they
have plastic printers like the ones that
we have in the library they also have
rosin I don't know if it's a formlabs
one or two and they're one of those and
they also have a powder based and that
can do multiple colors so those are good
options if you get into something that
you really want high resolution go visit
the nano scale research facility let's
locate it on Center Drive they're very
friendly there it's not quite set up to
make it easy where you just walk in and
you pay and you have to go through kind
of using chartfields and have it
attached to a grant but they have a poly
jet printer so do you remember the one
that was showing where it's spraying out
the
the liquid droplets and curing that's a
poly jet and it can do multiple serials
in the same model and so they've been
printing out specimens from the Museum
of Natural History and we had some of
them on display in Marcin recently but
they were CT scans of say a lizard and
you could see the inner organs and the
you know the skeleton inside and the
exterior so really beautiful prints they
also have a CT scanner and so these are
things that you'll need to pay a bit of
for but they're available to the
community and they're they're really
great to work with there are some other
options online so shapeways sculpt do i
materialize these are online services
that say you want to have something
print out in gold or silver or or
plaster or whatever they have about you
know 20 25 different types of materials
that you can then you again you upload a
model you tell them what you want and
they'll mail it back to you so there's a
lot of options out there is there any
questions about 3d printing yeah
pla in transit designing your own
filament is that what your yes and there
are people definitely developing new new
filaments mixtures new formulations you
know with this type basically if it can
soften at 180 to 280 degrees celsius
then you can use it in that type of
printer at poly lactic acid
yeah so it's dried from plant starch
close to well there are concrete 3d
printers and those are beyond large
scales I haven't seen anything that's
this design for kind of a smaller scale
3d printers I mean there's there's
people who are 3d printing houses so
over in um over in fine arts they have a
clay 3d printer play yes where it's you
know the slip this is actually extruding
it and then they fire it there is and
bronze right and so there that's another
thing they're doing is that they're
taking so even just PLA and they're
mixing it with different additives so we
do have some wood filament still and
Marsten that's kind of one of our secret
filaments from a project that you can
ask about now that you know difficulty
with things like that no woods not so
much but say bronze and I've held a
bronze 3d print a conference and it's I
mean it feels like bronze is very heavy
you can polish it and it tends to
destroy your nozzle because of the
abrasiveness of the particles coming
through and so you know it eats up your
3d printer since you know we're trying
to keep down costs right but on your own
3d printer that would be something to
try and it is pretty amazing yeah
[Music]
right right so I you know in essence you
know first of all these are being
subsidized by student technology fees so
at some point perhaps a free filament
runs out we have a lot of it still but
the 15 cents grams you know pays for the
wear on the machines and our labor
well so we we are willing to work with
you in making the model it's very
time-consuming in a lot of cases to go
through and fix a model for printing but
what we do is when we see something come
through or that either the person says
you know it's okay for printing or just
you know we can tell it's not going to
work out we'll get back to the patron
and you know we'll kind of show you
screenshots this is why isn't working or
come in everything's when things are
really bad we'll say you come in and
we'll we'll talk about this and I'll
show you some software and you know if
if we can do it within you know thirty
minutes we'll do it together otherwise
you know sorry
has it turned off and then we'll help
you you'll go through it we also do
teach workshops we have a workshop
coming up in another month or so on
meshmixer
I don't um but let me show you where you
can jump to web yeah you're saying that
if you go to the Science Library that's
where I work we have a link here to 3d
printing here's all the information so
we have a guide and then this is the
website I was telling you about and you
can contact us here so we do have a
three dollar minimum see if I can think
about so I want to say that this was was
about five dollars and this was actually
even though it doesn't look you know too
much different perhaps in size this was
I think a smidge over twenty because it
was covered in a support material and
that's another reason you want to try to
minimize your support material because
it minimizes cost and time
any other questions yeah so for the
majority of our printers they're just a
single extruder and so that would just
be a single color we do now have you
have at least two dual extruders so they
can do two materials at the same time so
you do two colors um we are still
playing around with it so this is I have
a I have an example here this is
actually my home printer but it's a frog
I don't know if you can see it well it's
two colors green and pink and so when
you're doing a dual color or it there's
even printers with Forks jurors using
ffs tile if you're doing say powder
based you can do almost full color you
have to have a model per color and then
they're co-located and so we're the pink
is the green can't be if that makes
sense and so the way it prints is it
still doing the same you know layer by
layer but it'll do the pink color first
and then in that same layer it will go
through and it'll do the green and it
moves up and it does that over and over
again so your suitor nozzles they have
to be very well calibrated because if
they're even off just a bit as the one
color goes through it can you knock your
model it can actually you know push it
off the bed or damage the print and then
also they need to be again calibrated
well enough that the two colors will
merge together so they're not you know
this they're in the same space but
they're separate separate lines if you
look at this some of it's fairly well
merged and some of its kind of separate
yeah we were hoping to get this paper
based 3d printer where it's sheet of
paper and it's full color cuz it's ink
you know like for me inkjet printer and
then it has a carbon or a diamond blade
where it slices the parts and it glues
it together like with Elmer's glue and
stacks up together and produces what you
know the websites look like beautiful
models and we we try to get one for
about two years and they just had
distributor problems and we were never
able to get one in the
the money just disappeared so I'm hoping
for another tech fee cycle that I can
request it once they're available I
don't there's there are other
possibilities out there yes we have an
under under if for uninterrupted power
supply attached to our large printers
because that happened to us to where we
were having a renovation and
electricians came and they accidentally
cut the power to the room and we lost
some jobs we have a UPS yeah and again
you know with these types of printers
you even two hours in you don't want to
lose your model and so make sure your
computer doesn't go to sleep or it's not
a battery powder any other questions
about 3d
so if it's if it's two vertical colors
that's when you need to have to tune the
two nozzles because it's doing layer by
layer up if you can rotate it so it's
two horizontal like it like a birthday
cake for example layer cake there
actually is a trick and and you have to
babysit the printer but when it gets to
the point where you want to change the
color you can pause the printer unload
reloading the new color and then
continue we've also done it where we
timed it really well and we snipped off
the the filament and we just followed it
in with a new color it's not easy
no um but if you really care about it
and you're doing a small model then it's
worth it
there there is something called the
mosaic palette that was on Kickstarter a
couple years ago and it's a device that
you'll have multiple colors and feed
into and then depending on what color
your layer is it'll feed in the right
color I've seen an action but we don't
have one of those but again it's really
finicky and it's a lot of work and your
model you have to specify your you know
it so at that point you have to specify
the color of that particular part of
your model so that's added information
you have to have painting works really
well too any other questions yes have
you seen that done make your name
afterwards because I've seen it in
magazines but I've actually never seen
in person
is that just texture or can you actually
do features as well
does it preserve it does really well I
mean if it's not handled too much I mean
we're creating art with it so yeah we're
experimenting with textures but yeah
it's pretty neat there another comment
okay so drop 3d printing now and we're
gonna move into augmented reality just
perhaps the more technically challenging
part of this presentation if it works
out so how have you all had a chance to
download HP reveal great ok so you want
to open that up I'm gonna talk about it
start off you know give an introduction
to augmented reality kind of some uses
here at UF but then we're gonna jump
into HP reveal and and play around with
creating your own aura okay so I've been
in reality as we discussed earlier
that's when you you overlay digital
media on top of the real world and so as
a user you're seeing both things in the
physical world and whatever digital
media that is and that can be it can be
an image it can be text it could be a
video it can be sound it doesn't have to
be an actual image so sound is
considered augmented reality as well
this is not this is different of course
from virtual reality where VR is that
user is transported entirely into
general world and so AR is both the real
and the digital together there's
different types of augmented reality I'd
never actually before preparing this
presentation thought about the different
categories but there there are distinct
types marker based this is when there is
say an image that you know precisely and
your software knows exactly what that
image looks like and when it sees that
image that it then knows to trigger
this new digital content and you know in
terms of software that's the easiest
because you're recognizing something
exactly and you may be you know there's
different shading it to be concerned
with different angles but that image is
the same then there's markerless so this
is now more taxing for your software
because it's looking for features it's
not looking for an exact replica
necessarily so it's using object based
recognition to try to understand to map
out what it's looking at and when it
sees something it recognizes you know
features of it knows how to - so then
correlate it with whatever overlay
whatever digital media you want to show
in the real world you can also use this
with location-based information so so
say you have your tablet you have maybe
GPS enabled or the accelerometer and so
not only does it see something it can
figure out what it is but it's also in
the right location to put over that
content I'm super position now this is
this is a very closely related to the
marker list but this is when then
digital objects are overlaid entirely
even entirely obscuring things in the
real world so for example IKEA now has a
virtual catalogue app that you can send
your room and you can put furniture in
different places and it makes it look
different like your room you know is
populated with IKEA furniture and then
there's projection based and I'm not
gonna go into this too much but it's
really interesting this is when you're
gonna project a light you're forming
some sort of an interface onto the real
world so say an augmented reality
keyboard where the keyboard would be
there and the the software can can sense
your finger movement and that's then
triggering a response in the software so
when you think about research and
teaching and you talk about here at UF
what are you sister a are it's not all
entertainment just like 3d printing
isn't all
about printing out Yoda heads talked
about several examples there using
English is anyone here from English
trace okay I'm gonna talk about their
research because they're doing some
really neat things with social criticism
and augmented reality it just says
Angela showed you with the Holland's it
lets you put digital objects into the
real world and manipulate them and that
was pretty cool I thought and we oh and
we have Holland's that you can check out
at Marston as well along with HTC vive
and oculus rifts so that's downstairs it
made at us unless you are you can
augment of reality to put information at
point of need so I don't know if you've
seen you know advertisements for the
hololens where the person is trying to
fix their their sink and they're able to
put say a YouTube video right next to it
or even point out you know fix this part
fix this part and so that information is
right there um I've heard of factories
now where they're using augmented
reality to you know you're looking at a
machine to indicate what parts are which
and so that's going to reduce the need
for for training necessarily if that
information is always there also you
know I don't know it's called word lunch
at this point probably google translate
I think absorb word lens but who had a
chance to use Google's app where it
translates is superimposes the
translation of text so it's really
amazing especially when you're traveling
you can hold your tablet up and it
recognizes the words and in the same
font so kind of using that superposition
it it translates the language so you're
looking at the sign say in English I was
at the Museum in Washington DC and I
tried it they had a sign there from the
Berlin Wall and it was in three
different languages and I did have to
tell the software at that point what
language it was looking at but I was
able to translate it into three
different you know out of three
different languages so that's a very
useful and then also improving
accessibility of campus and its services
so a project that Todd and I are working
on actually uses beacons which are
little little tiny devices that send out
a unique identifier and we have a
project that's been working on there's a
class called
the R for social good it also includes a
R as well and they're always looking for
projects in this class class has 100
students and so last semester they they
helped build an app for us where the
idea is that so if the Cicerone tour
goes around campus and say you know if
English isn't your your first language
or you don't speak English at all or
your your hearing impaired or you know
visually impaired so you have
accessibility issues that you have your
smartphone it's on this app and when you
get say to the library it senses you're
at the library and the scissor owns are
giving their tour but the phone is going
to give you a translation into there's
20 different languages at this point or
what we're hoping to do is in terms of
augmented reality is to a say if you're
hearing impaired you sign language
there's a sign learn from video that
will pop up and translate what the Terr
guide is saying that's an audio version
that you can listen to as it you know
senses where you are so that's a project
that we're working on it's it's going
yeah okay so moving into here's a
project that the trace this is a a
research group in the English department
that are using emerging technologies for
for criticism and for writing and this
is a project done by Madison Jones and
Jake green and this is for for ghost
bikes and so ghost bikes you might have
seen some even your campus when a biker
is killed an accident people paint a
bike white and they put it the scene of
the accident - you need to recognize
where it happened but because of various
reasons those bikes are removed
sometimes fairly quickly and so they
have a project where they are then
augmenting their putting the the digital
model of a ghost bike on the location
where that accident occurred they've
done it I think both in Gainesville and
in Jacksonville so they used our rasma
for this or HPV I'm just probably say
rouse my fro most of it and so you can
actually follow the the death drivers
Channel
and it'll tell you where to go and you
can look at the ghost bikes
I'm SeaWorld at SeaWorld with SCE
so this is another project at a trace
Sid Dobrin and Melissa biology and Jake
green this is actually a very involved
project where I mean if you recall there
was a documentary of the blackfish I'm
kind of raising awareness of issues with
marine life at SeaWorld and they wanted
to so what they did is they created an
augmented reality app that if you go to
the park they have there's different
signs across the park that are augmented
and so if you have the app and you you
have to have that specific app otherwise
you have no idea it's actually there you
can pull it up and you can look at it
and it overlays information about maybe
what happened there or you know the
what's going on with the animals or
different bits of information and so
they did it kind of secretly at the park
they had some park people following them
around as they were taking images of the
signs but I think it is a very well-done
project and you can download that next
time you're at the park you can you can
look at it
um this is now isn't that something at
UF but I just thought this was so cool
idea of superposition so people who are
dentistry really is taking advantage of
emerging technologies especially in 3d
on or a lots of 3d printing 3d modeling
there's a lot of tutorials out there for
dentists so this is a case where a
person the the dentist is there and they
can adjust at real-time so a person's
giving feedback on what they want their
teeth to look like and the dentist can
adjust it and they can see immediately
what that's going to look like and then
it can output output the 3d model and
they can turn that into you know a new
set of teeth or overlays or whatever
they're called so I just thought that
was really
I know there's dentists here at UF that
are doing quite a bit with 3d technology
all right another local project
Shannon butts and Madison Jones and Jake
green and Jason Carter so you see some
of the same names and Kenny Anderson
again there they're out of trace and
this was a grant that was funded by the
the Bob Graham Center so last year they
got a grant to create this and this is
creating an eco-tour a Paynes Prairie so
the latrine trail and the sweet water
the new branch the park that you can
walk through and just like if you're on
a tur and you have a digital turth at
you can listen to as you walk around or
an audio tour excuse me this is now an
augmented reality tur so as you're going
through on the path there's different
locations and you know there there's
four or five at this point and you know
they're they're definitely hoping to
reach see the entire park but as you go
to that that point then you can look at
whatever is featured there and it's
going to give you information about the
geology the history of that spot talk
about kind of the environment how how
the water flows through so it gives you
you know historical information and
environmental information and they're
hoping that then the you know the
community will will download this app
and participate so it's right now it's
at a github page I think I'm gonna try
to make the slides available later on so
if you want to go and explore this site
you can alright so if you want to get
into to building your own AR apps there
are different ways to do it if you want
to if you know how to program you can
make it natively and you can do it in
unity it's kind of preferred and
euphoria is an extension that you can
use with unity to create an AR or VR app
so the other thing with with augment
reality is that a person who
wants to experience it or have it they
have to download the app and I think
right now you know that is kind of one
of the big pitfalls they are is that if
you don't know that that content exists
unless you have signs everywhere saying
your download ar-ar-ar
you know a person doesn't even know that
you know this room has probably been
augmented and we have no idea at this
point and so you have to get the word
that there's an app involved
it's a download so a person has to have
a smartphone internet enabled there's
also these services that are web-based
that lets you create a our content and
so instead of downloading a specific app
the the viewer has to download that
company's app and then you can follow
just like on Facebook you follow
different channels follow different
creators and you can see what you can
see there augmentations so for example
this room if say we all create new or as
is the word for that of razmik uses you
have to be following me in order to see
mine because if we augment the same
chair you know which one which one does
it show and that's actually an issue
sometimes with say you're in the grocery
store so companies are really into a are
because this is a way to push more
marketing and more information at you so
who owns that actual physical space
who gets to augment it you know that's
one of the questions that say trace
they're really interested in will they
go see world you know did SeaWorld have
the right to keep them out of the park
and not augment it or you always if kind
of fair game for anyone all right but HB
reveal Aurasma they get around that by
following these different creators and
so there is layer and there's wicket ood
but but Aurasma really is at least in
education is what it looks like to be
the most popular at this point so the
way it works I want to stick with
Aurasma HP reveal is kind of a I think
it's a lousy name
the service the software lets you create
these auras and the aura is made up of
you have a trigger image and so it can
be a photograph it could be it could be
you know an icon a logo whatever but
it's an image that's recognizable and
hopefully it has enough detail you want
enough color variation that you think
about the software has to be able to
recognize it and then you overlay it
with digital content and that content
can either be another image it can be a
text you can actually put a link to a
website so that when you interact with
that trigger image it causes your your
smartphone to do something so to pull up
a website you can do audio you can do
video and you can do 3d models so it
kind of ties back into our our 3d
conversation and then if a person knows
where it is and they're following you
they can focus on the image and it pulls
up that overlay so with 3d models um 3d
and Aurasma is actually fairly
complicated I was hoping to show you how
it works I do have kind of a demo 3d
model but they make you jump through
some hoops to get it in images very easy
basically every other overlay is simple
except for 3d models you have to bundle
it as a tar file and so you have to know
how to create a tar file there's
software for that and then your format
we know we were talking about models
being an STL format it needs to be in a
Dae format a digital asset export so
basically you have your model but it
also has lighting and it has texture as
being exported and so you have to export
it using something called Coolatta
that's the export format and you can do
that at a blender you can do that a3 yes
max or there was another one Maya so a
lot of your modeling software won't let
you export it's a bit more complicated
because they're gonna be Erasmus taking
this model and they're putting it yo in
context of the real world so it needs
color it needs to understand how to
lighting affects it so you get a texture
file and you need a little some nail
which is named thumbnail
so it does take some work but it is
possible to say you get a structure
scanner you scan it you're gonna put
into blender then you can export it out
to Dae file along with the texture and
then you can put in Aurasma so it is
doable so now let's let's do the demo
part let's see if this works so if you
I'm gonna split my screen if you want to
open up a rasma or HP reveal they have
some popular auras that you're
automatically following and I have a
video here so you hold up your phone you
should see kind of a blinking blinking
circle and hold it over the $20 bill and
then for those of you who don't have it
I'm showing what what you'd see this is
a very complicated aura with kind of
exploding video anything in a waving
flag god Bless America so you know if
you have a $20 bill in your wallet you
don't have to focus on the screen you
can pull out the dollar bill oh you got
one back there if you have one and
there's actually a one dollar bill
that's been augmented as well that you
can look at now and that has a different
so you can augment money I mean really
any image that has strong enough
contrast enough detail for the software
to recognize it you're gonna be able to
augment it now I thought you know if
your bill is kind of torn kind of
crinkly it's not going to do so well let
me see if I can
I try to connect my phone here
then they're sound obviously okay I'm
I'm hearing my phone at this point
everyone have a chance to see the $20
bill and do its thing okay okay so on
your with the app installed you're able
to create auras that you'll be able to
view privately but if you actually want
to create something that everyone else
can look at at least do it easily you
need to do it off their website and its
called a Rasmus studio it's gonna give
you a lot more options and so I'm gonna
try to create some auras in front of you
and if you want to find it my user name
is Sara and dippity so it's SAR and n
dippity di P ity and so you can click on
follow let me see if I can oh now you
can see my phone
okay sonic I'm using the Android version
I think the iOS works fairly similarly
might be some slight differences okay so
they have once you explore oh I highly
recommend taking a look at the Back to
the Future one let's just do that one
right now because that is pretty that's
an example of a 3d model with sound
and actually looking at the time we're
not going to do back to the future but I
highly recommend it so I'm going to show
you briefly how to create a new aura
when you log in there's a discover
section there's assets assets are both
your triggers and your overlays and so I
have two images here that I've set are
my triggers and then I can look at my
overlays and remember overlays can be 3d
they can be sound they can be another
image I have a gif here that I
downloaded from github so you know
either have them already there or when
you're creating the aura it gives you
the option to upload at the same time
and then you click on create new aura
and so you're going to pick your trigger
image and that's the one that is
someone's walking around or maybe
they're looking at a pamphlet and you
have an image there I'm gonna do the UF
logo that's everywhere I did have the
ability to say give it certain GPS
coordinates so if I wanted that that
aura just to work at a certain location
that's would be how I I would I would do
it but then no one else would ever be
able to use that or because you have to
be at that location
we're just disappointing sometimes I can
mask out portions so say I have a very
complicated image and I say there's a
bunch of branches and I just I don't
want those and because I just care about
the recognizable part I can mask that
portion of the image that's another
option but say it's good right now the
logo is great I go to next and now I'm
going to give it the overlay when they
see that logo what should happen and I'm
going to do like animated gif there okay
and I can resize it I can move it about
this is what they're gonna see on their
screen when they goes across when it
recognizes that logo and over here I can
have options so I can say not only just
pull up this this animated gif but I
want the user wheel to interact with it
so say I want them to be able to click
on that and I want to bring up the UF
homepage I can do that yeah you can see
that pretty well so I can say add an
action when overlay is tapped and
there's other options double tap faded
in started finished you can even give it
a time delay I'm going to add an option
and I'm gonna do loader URL but you can
actually add on up to 50 different
overlays to make a really complicated
aura but I'm gonna do a URL you have to
tell it's an HTTP because that's you can
actually also tell it to do an email so
all those commands in HTML you can do
you can add those in so I'm going to
tell it to go to the home page and save
that I have the ability to preview but
that doesn't help you because you can
actually see my previews so go next I
can give it a name logo I'll get a hash
tags so think about Twitter that way
people can find things so I'm gonna say
hashtag UofL right now it's it's shared
so I think once I save it it's going to
be public because you can have private
auras you can have public auras so
public anyone can see it as long as
they're following you and then I can
close it and actually it looks like it
kept it as private but since you can see
my we'll just do it on my my phone so
you can see that okay so I'm gonna say
ah
so they're recognized it I could take a
picture of it on my smartphone and I'm
gonna click on that gif and it opens up
the website but that'll work huh
let's take me about five hours to figure
out how to do that
so I'm there are lots of options I mean
you can see that I could add on sound at
the same time you know play the fight
song yes which comes up and or you know
if you're another project that tres is
doing is they're augmenting tarot cards
and as you if you look at the image or I
should they're also doing comic books
so the League of the what is it the
league of extraordinarily gentlemen
parts that are in different languages
they've augmented it to put the
translation over the words and so
there's all sorts of things you can do
with AR not just marketing for for
universities so my times up but do we
have any questions about AR people have
their own projects that they want to
talk about or if you have a photo is out
of state change it from your desk for
your and it'll update to them so some
examples like they wanted to do kind of
like treasure hunts for a museum and
after that gets tired after here so
you've been updated the images
activity Thanks thank you
we used it I got the horrible job of
being a yearbook editor for our high
school and I we started in the red so we
had a ton of yearbooks old yearbooks we
found some of the people that were in
the yearbook and we used your asthma to
record videos and things like that and
then we resold the books Wow the app and
then now we use the app for at the back
of the yearbook because unfortunately
I'm still a yearbook editor our advisor
we do messages from parents so those
senior ads that are in the back of the
yearbook I think and do that your ass
but and then they're talking to their
kids so it's a it's a no brainer so what
what high school are you with here
Central High School oh that's really
neat I can see why that sells mom's
piled is there a comment in the back
any questions anything else all right
well thank you so much for your
participation and I guess lunch time
next right
[Applause]
