​ ​
temperature:
​ ​ ​
50 ​ ​ °C. ​ ​ You ​ ​ can ​ ​ set ​ ​ the ​ ​ bed ​ ​ temperature ​ ​ up ​ ​ to ​ ​ 65 ​ ​ °C ​ ​ depending
on ​ ​ the ​ ​ size ​ ​ of ​ ​ an ​ ​ object. ​ ​ (larger ​ ​ object ​ ​ means ​ ​ higher ​ ​ temperature)
● Heatbed:
​ ​​
Make ​ ​ sure ​ ​ the ​ ​ surface ​ ​ is ​ ​ clean ​ ​ as ​ ​ described ​ ​ in ​ ​​ 6.3.2 ​ ​ PEI ​ ​ print ​ ​ surface

​ ​
Some
​ ​
very
​ ​
soft
​ ​
flex
​ ​
materials
​ ​
can
​ ​
bond
​ ​
to
​ ​
the
​ ​
bed
​ ​
too
​ ​
much
​ ​
and
require ​ ​ use ​ ​ of ​ ​ glue ​ ​ on ​ ​ the ​ ​ bed ​ ​ as ​ ​ a ​ ​ separator ​ ​ to ​ ​ prevent ​ ​ PEI ​ ​ damage.

Composite
​ ​
materials
Composite materials (woodfill, copperfill, bronzefill, glow-in-the-dark, carbon or aramid
composites and many others) consist of a main plastic base and a second material in the
form of dust. These materials tend (except for wood composites) to be very abrasive,
therefore a hardened nozzle is strongly suggested for long-term printing. A larger nozzle is
recommended while printing with wood composites (0.5 mm and up). Please use
corresponding print settings in Slic3r or PrusaControl as print parameters can be very
different
​ ​
depending
​ ​
on
​ ​
the
​ ​
plastic
​ ​
base.
The
​ ​
first
​ ​
step
​ ​
in
​ ​
polishing
​ ​
is
​ ​
sanding.
​ ​
It’s
​ ​
a
​ ​
good
​ ​
idea
​ ​
to
​ ​
start
​ ​
with
​ ​
a
​ ​
coarse
​ ​
grit
​ ​
size
​ ​
(80)
​ ​
and
slowly ​ ​ move ​ ​ up ​ ​ the ​ ​ grit ​ ​ table. ​ ​ After ​ ​ sanding, ​ ​ a ​ ​ big ​ ​ improvement ​ ​ in ​ ​ polish ​ ​ can ​ ​ be ​ ​ achieved
with
​ ​
steel
​ ​
wool
​ ​
or
​ ​
a
​ ​
brass
​ ​
brush.
​ ​
If
​ ​
you’re
​ ​
still
​ ​
not
​ ​
happy
​ ​
with
​ ​
the
​ ​
finish,
​ ​
you
​ ​
can
​ ​
try
​ ​
wet
sanding ​ ​ with ​ ​ a ​ ​ very ​ ​ fine ​ ​ grit ​ ​ (1500).
