- [Instructor] When 3D printing,
your slicer will put one or more shells
around the object.
Then it will fill it to
a particular percentage.
This is known as the infill percentage.
However there are several different types
of infill that we can use in our print.
So we've printed out
some lovely boat hulls
in the form of partially printed benjis
to have a look at a few infill choices
for your 3D printing pleasure.
(upbeat music)
first, let's have a look
at 2D and 3D patterns.
2D patterns print quite
well and are quick to do so,
but have one important caveat.
They're able to withstand
force vertically.
They aren't all that strong with force
from any other direction.
The same caveat applies
for 3D patterns in reverse.
In that it's not super strong against
vertical forces, but because each layer
is varied in the print,
it can withstand force
from other directions
quite well.
What if you want some
squishiness to your prints?
Then it's probably best to consider this,
a flexible patterns.
These are best used when printing
with flexible filament and you require
some squishiness to your print.
Now the one we have here
is a concentric pattern,
but there are more available,
depending on the level of
squishiness that you want.
Lastly, we're looking at fast infills.
Because straight lines
are quicker to print
than corners or curves,
these are typically the
fastest infills to print.
However they aren't exactly the strongest,
but are sufficiently good for prototyping
or test prints.
Now it is worth remembering
that changing the infill
is merely an optimization
and in most cases,
the standard infill pattern
will work just fine.
So there's no real need to obsess over it,
unless you're like us and you want to.
