Other option for
​
multicolored
​ ​
print
​
is to
​ ​
use the
​
filament
​
change option. Choose
the
​
Tune
​
and then
​
Change
​
filament
​
option during the
​
print
​
. The printer will pause
the ​ printing ​ process, unload the ​ filament ​ and signal you to insert the new ​ filament ​ .
The procedure is the same as above.
You should always use the same material or combine materials with similar print
temperatures and settings.
10.7 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.
10.7.1 Printing with support material
While printing
​
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 the left column.
First you have to check the ​ Generate ​ support ​ ​ material ​ box ​ (3) ​ . 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 is
needed.
​
Enforce ​ support ​ option
​
(5)
​
is used mostly with small
​
models
​
or
​
models
​
with a small
base to prevent the object from breaking or tearing out from the bed.
