Wassup everybody, this is Cubastic.
In this video I will try
solve this impossible puzzle.
Apart from the fact that it’s very complex
and it looks cool, it’s also
very special because I printed it on my 3d
printer.
Many of you, guys, enjoyed my previous video
about 3d printing, so I`ll
be very happy if you back me up here this
time as well.
Subscribe to my channel, because unfortunately
many people watch my
videos without a subscription.
I really want to give you cool, high-quality
content.
Even though I’m
making videos at home right now, not in the
studio, I spend three times
as much energy making videos for you and I
struggle to make them very
interesting.
So please subscribe to the channel right now
if you haven’t.
And if you
have already done it, don`t forget to ring
the notification bell.
Because only if the bell is activated, you
will be able to become one of
the first to see my new videos and chat with
me in the comment section.
So, start commenting right now.
Let’s go!
You asked me a lot of questions and one of
the most popular was: show
us how 3d printing works, what does it take
to print something on a 3d
printer?
And in this video, I’m going to describe
step-by-step how I created
this...
I haven’t created it yet, but I’m going
to show you right now the
process of creating this puzzle.
And I hope you will understand the
awesomeness of 3d printing.
Let’s begin right now.
To print something, we have to find what we
want to print.
There is a large number of websites and applications
on
the Internet with a list of 3d printing models.
Of course, there are many puzzles too.
We’re going to take one of the
coolest, one of the most popular and awesome
puzzles of all time.
This
is a 3D puzzle called Dr. Brain Breaker.
Nice puzzle, it looks great and probably it
is a quite complicated one.
After we have selected the model and downloaded
it, we need to import
it into a special 3d Editor, where we can
look at the result that we will
get after the printing.
We can also choose a color.
And I had a couple of choices: orange,
beige, yellow.
But what I liked the most was the combination
of
metallic and green.
I really like the combination of these colors,
and I think they should
look very nice.
Now let’s start printing.
If you think that this is it, and now we can
insert our flash drive into the
printer and start typing, it’s not.
The most difficult and interesting things
lie ahead.
When we have already selected the model and
selected the colors, we
proceed to the most difficult part of the
preparation for 3D printing.
After that, we import the model into Slicer,
special software that creates
code for 3d printers to make it operate correctly
during the printing
process.
And to do that, we have to enter a huge number
of parameters.
You can
see here on the left side the whole list of
parameters which consist of
thousands of settings, and you have to choose
the right value in each of
them in order to to make the quality, temperature,
height of the layer,
and printing speed the most suitable for us.
Using Slicer, we can see how each layer would
look like, for example,
our skull - the base of our puzzle will be
printed like this.
It will be
filled with these special hexagons inside
to save material, but to make a
model durable enough.
Also, there are a lot of difficulties here,
and they’re going to be a little
bit challenging for the printer.
When the lid starts printing, we print it
almost in the air.
And it begins to hover over inside these filling
elements.
Some of the first layers here will be printed
in the air.
It’s not
an easy job for our printer.
But I think it will deal with it, and we can
do
it.
We have created G-code, entered all the values,
now we can save this
code to the flash drive.
And then we insert the flash drive into the
printer with a great pleasure and awe.
By the way, the program tells us it’s going
to be printed in about 14
hours and 50 minutes.
But, in fact it’s going to take a lot longer.
I think
we should multiply this time by one and a
half, or even two.
But I have no doubt that our model will weigh
exactly two hundred and
thirty-five grams.
Well, let’s get started!
So, now the printer is starting to warm up.
Let`s look how it`s going.
The extruder is heated to 90 degrees and the
canvas is heated to 27 and
a half degrees.
But we have to heat the table to about 70
degrees, because plastic
requires this temperature.
As you can see, all the values are set.
Now we
just have to wait for the printer to start
printing.
Now when all the values have been set and
the printer is warming up,
we can go to the printer display and choose
our 3D model stored on the
flash drive, and start printing it.
Now, when the printer is fully heated and
the temperature reaches the
required values, printer will automatically
start printing.
We just have to
wait.
Printing the first layer is one of the most
important steps in 3D printing.
In most cases printing quality of the whole
model depends on how well
the first layer sticks to the canvas and how
well it is printed.
So far, we’re doing really well with the
first layer, as you can see, the
line by line is very smooth.
I hope, that now it`s easier to understand
how 3d printing works.
As you can see, this layer of plastic, line
by line,
layer by layer melts of the printing head.
A certain amount of plastic
melts out into a certain place.
The printer uses printing parameters we
set in the Slicer.
Well, the printing has been initiated and
it is going quite successfully.
I
hope everything will be all right, I just
have to wait until tomorrow to
see the results of the printing of the first
part of our puzzle.
But you’ll
see it in a few seconds.
Oh my God- 20:51.
That’s a lot longer than I thought it would
be.
But it
just turned out to be really awesome.
God, it looks so stunning.
It’s time
to take it off the canvas.
Great!
It looks really cool.
Once I had a situation: when I was taking
a ready-made model off the
canvas, I accidentally ripped off some of
the lower layers.
They
remained glued to the table.
The model went bad.
Lots of hours of printing went down the drain.
I
don’t even know which way to get to it.
Oh, I guess this way.
Just look at how great the colors are on its
sides, I’m really happy with
it.
But that’s only half the work, because we
still need to print a lot of
stuff to fill the brain.
There are a lot of details here, too.
I don’t know how many printing
sessions it’s going to take, so there is
no time to wait, let`s do it.
The 
difficulty of the next construction is that
it’s not one big piece –
there is a large number of small elements.
And as far as I can see, there
are 28 elements from each side.
I mean, I have to do at least two
printing sessions.
And now the biggest challenge is not only
to customize the print, but
also to place on the canvas as many details
as possible.
And I think it’s
going to be an impossible challenge.
I’ve already done six, seven, eight.
And I think that’s it, they don’t fit.
9.
I haven’t printed out the puzzle yet, but
I already have to solve it.
It
turned out, putting all these twenty-eight
elements (which is exactly
how many pieces you can put in one half of
the brain) on one table was
a very difficult task.
No matter what, I’ve already done all the
settings.
It’s going to be done
this way.
All I have to do is to save everything to
the flash drive.
As you can see, the estimated printing time
is 15 hours and 37 minutes.
196 grams of plastic will be used to print
this Model.
All right, I got the flash drive out, and
now it&#39;s printing time.
Let’s go.
Well, the head brain printing is running.
Head brain printing
sounds like my diagnosis).
It’s already started, and there is no room
for
errors.
This green-colored plastic reel here has exactly
enough plastic to
print just these two groups of details.
So I have no margin for errors.
Guys, It took me a week to shoot this video,
a lot of work left behind-
the-scene, so please back me up here, press
the like button, if you still
haven’t done it, subscribe to the channel
if you haven’t done it yet.
I love what’s happening right now, even
though it’s very difficult for
me to film it and do it alone at home instead
of doing it in the studio.
But I hope the result is worth it.
If you think so, write your opinion in
the comments.
So, we&#39;re moving forward.
Yes.
Things got out of hand here)
I ran another print.
And this time, I decided to divide the elements
into
three printing sessions.
I think it&#39;s much more appropriate to
do that
way.
I hope it will lower the risk that printer
will mess everything up again.
But I had to sacrifice the durability of the
details, I had to reduce their
weight because I have very little plastic
now.
I will be very happy If It
will be enough for all three printing sessions.
Please back me up.
I got into such difficult situations to make
this
video, but I’m sure you’ll enjoy the result,
so, guys, like, subscribe, if
you haven’t done it yet.
The printing is finally complete.
This is the third printing session, the
third batch of our puzzle elements.
It’s been three days since you last
heard my voice.
I’ve been waiting for this moment for a
long time and
I’m really glad that all the details have
finally been printed out.
Let’s take them off the glass and remove
support structure.
This
printing lasted almost 10 hours.
Each of these three batches of the details
was being printed for 10 hours.
Damn, I’ve never printed anything for that
long.
This is probably one of
the longest projects I’ve ever done.
I hope the result will be worth the
time.
The details are pretty easy to separate from
the glass, but let’s see if we
can just separate the whole support structure.
And these are all the
details that I printed out during three printing
sessions.
There’s a huge
amount, and I’m kind of afraid to imagine
how I’m going to put all this
together.
Let’s clear all these pieces of the support
structure.
Since we cannot
print in thin air and the laws of physics
and gravity also account for 3D
printing, some objects with overhanging parts
need a support structure.
Let’s look at this piece here and this element
here, they are completely
printed in thin air.
So the Slicer and the printer built this kind
of supporting structure which
doesn’t allow printer to print in the air,
giving them some kind of
support.
Of course, when the details are printed, we
can easily remove the
support to make the detail look as
it should.
Okay, that’s it.
There are so many details.
I’m going to freak out trying
to solve it.
Finally, all the printed details of this puzzle
are on my desk.
I
can see now, it is going to be one of the
most difficult puzzles I have
ever solved.
I’ve never solved such a big 3d puzzle.
This will be my first experience.
To be honest, I’m very excited about the
fact that this puzzle was made
by me personally with my 3d printer.
As usual, I’ll be timing it and see how
long it takes me to solve this
puzzle.
You can make suggestions in the comments.
How fast do you
think I can solve this puzzle?
I push the start button.
And the first thing
I’m going to do is to divide these details
into two batches, because, as
you can see, there are reflected details of
the left and right hemisphere
of the brain here.
Apparently, they’re going to look the same.
So I need to find the same
detail and put them into two batches.
It’s gonna take some time,
hopefully not too much.
Okay, here are the same ones.
I’m doing it
pretty fast
I can`t find the same details.
Oh, here they are, okay
I spent about seven minutes just dividing
the details symmetrically.
Well, I think we can get started.
This is going to be very difficult, but,
wish me luck.
Let`s do it!
It fits well from one side here.
Here we have these special extra recesses
around the perimeter of the head.
And you can guess where the element
might go.
But it doesn’t really help me now.
So, where did I get it from?
That’s the first problem.
This piece was here…
Maybe I should start with some central parts
like this.
These big details
are going to be right in the middle, because
we can’t put them anywhere
else.
So the
details are fixed fairly and it seems like
we’re doing it right.
But
I’m not sure that’s how it should be.
What if I`ll try to solve one
hemisphere and then another separately?
I think we’re getting somewhere.
I hope we are doing it right.
Well, at
least the puzzle is symmetrical; it’s reflected,
because otherwise I
couldn’t have done anything about it at
all.
Now we’re in the second row.
It’s a perfect match and at times like this,
I really don`t want to give up and I believe
that I can solve the puzzle.
God, it’s awesome, it’s an amazing puzzle,
very difficult and very cool.
Great, so far I’ve managed to place the
biggest elements, I see a niche
for them.
I see them match this detail, it fits into
the hole inside.
It’s
cool.
But the hardest part, the smallest details
are ahead of us.
Hard!
It’s so hard!
Damn, Just look at the amount of the details
I’ve
already used.
But I still have a lot of details left here.
I want to show
you this from the outside, but I’m afraid
to break it.
Look at the chaos inside.
This is the most difficult puzzle I’ve ever
solved, a very difficult one.
Actually, I don’t really like puzzles, but
to
be honest, this is the kind of puzzle that
drives me crazy.
Let’s move on.
By the way, look, I’ve been putting this
puzzle together
for an hour.
I hope I will solve this puzzle faster than
the printer printed
it.
I’m already doing it faster, and I need
to find a detail to fit into this hole.
I don’t know even how to show it to you.
Here, in this little hole, which
is inside.
It’s fenced-in by other elements.
And I can`t put this detail in
like this.
Probably right now I’m going to disassemble
everything I’ve just put
together.
The most important thing is to do it carefully
and not forget
where each detail was located.
I have to take apart the whole puzzle, you
know?
Everything, oh, no.
Let’s try another way, I’m going to solve
one hemisphere and then I’m
going to deal with another one.
Because it’s driving me mad.
Now is
that all?
I’m confused.
I’m going to remove the top layer, it’s
getting in the way.
I’m going to
leave only those elements, which touch the
main part.
I’ve more or less
remembered where every detail was.
Maybe I remembered) I’m not sure
at all So, we put this one right here, and
this one here.
Okay.
Okay.
Okay.
Okay.
We have to pull out these two elements and
put them together to make
one block.
And now we need to put that block in the right
place.
I
couldn’t have put it in separately.
So the next thing we’re going to do is to
fill all these holes down here,
so that we can use them as a base.
And we can put those pieces on the
top of it.
Apparently, it won’t be easy.
But I think we can handle it.
I put together the first layer here.
This detail here was the most difficult
one.
Now I’m going to try to find a reflection
of this detail and show it
to you.
Look, it has this end and this one.
A horizontal one and a vertical one.
And there are two holes which fit them.
It’s amazing, cool.
So I completely filled in the first layer.
Now I have to fill in the
remaining parts inside with these four elements.
Everything else is
going to be the roof for our brain.
I think it’s going to be a lot easier to
solve the puzzle at the end than it was at
the beginning.
Okay, I’ve already spent an hour and a half
solving the puzzle, and I
hope I can solve it in at least two hours.
This part has to be here.
Definitely.
I only have to move this structure.
That’s ok.
And this one is reflected.
I am glad, that it’s a symmetrical
puzzle, great!
And then we have this detail.
Yeah, it’s going to be quick!
Cool!
I’m
really happy!
This piece was right here.
I remember, this one goes here.
Now we’re building what we’ve built before,
so it’s not that hard.
Now
we have much smaller elements, it’s easy
to find the right ones.
I`m looking for the holes to see where the
detail fits.
And I often find
the right piece from the first time.
This one, for example, goes here.
Now I have to fill in all the space in the
back, because there`s the least
work done here.
Oh no, we’re carefully putting it back together.
Luckily, I remember
how it was put together, otherwise I wouldn’t
have done it.
And the last
couple of details.
Where should I put them?
Oh, that’s it.
1 hour and 37 minutes.
It looks so cool!
I didn’t think it would be so
beautiful!
Crazy!
I’m delighted with the result, and I really
like the way
this puzzle was printed out, and I really
enjoyed solving this puzzle.
I’m
so excited that I managed to combine my two
favorite hobbies: puzzle
solving and 3d printing.
So in this video, I was very detailed about
how
I was making models with my 3d printer.
In the next video, I will
definitely use a 3d printer to create new
puzzles and solve them.
But I
will not focus so much on the process of creating
the model itself, I will
pay more attention to the solution.
So thank you so much for watching
this long video through.
Every person who’s watched the video till
the
end means a lot for me.
Because you are the most dedicated, the best
audience I’ve ever had.
Thanks to you personally.
If you are on my

which I will print out with
my 3d printer.
Thanks everybody so much for watching.
This was Cubastic.
See you
next week?
Bye, and have a good time!
