9.6 Printing of non‐standard models
Slic3r helps you while
​
printing
​
the
​
non
​
­standard
​
models
​
as
​
models
​
with
​
overhangs
​
and/or
models
​
larger than a
​
printing
​
bed.
9.6.1 Printing with support material
When you
​
print
​ ​
models
​
you can find special cases different from standard
​
printing
​
. The first
case is
​
printing
​
with
​
support
​ ​
material
​
.
If you
​
print
​
an object with a gradient lower than 45° the
​
material
​ ​
overhang
​
would be
preventing the object to be printed correctly. Slic3r allows you to
​
print
​
such objects thanks to
the ‘
​
Printing
​
with
​
support’ function
​
. Support
​
material
​
is an extra structure printed as
scaffolding for the object ­ you can remove the
​
support
​ ​
material
​
after the
​
printing
​
is finished.
Choose the
​
Print
​ ​
Settings
​
tab
​
(1)
​
and click the
​
Support
​ ​
Material
​ ​
option
​
(2)

in left column.
First you have to check the

​
. Next item ­
​
Overhang
threshold
​
​ (4) ​ lets you set the minimal angle for ​ printing ​ the ​ support ​ ​ material ​ . Setting this item
to zero lets the ​ printer ​ detect problematic parts automatically and ​ print ​ ​ support ​ where it’s
needed.
Enforce
​
support
​
option ​ (5) ​ is used mostly with small ​ models ​ or ​ models ​ with small base to
prevent the object from breaking or tearing out from the bed.
