The ​ ​ best ​ ​ results ​ ​ are ​ ​ obtained ​ ​ with ​ ​ common ​ ​ scotch ​ ​ tape ​ ​ - ​ ​ just ​ ​ attach ​ ​ the
tape ​ ​ directly ​ ​ to ​ ​ the ​ ​ print ​ ​ surface ​ ​ and ​ ​ clean ​ ​ it ​ ​ after ​ ​ the ​ ​ print ​ ​ is ​ ​ finished.

Nylon
​ ​ is ​ ​ a ​ ​ very ​ ​ tough ​ ​ material ​ ​ suitable ​ ​ for ​ ​ mechanical ​ ​ parts.

Flex
Flex
​ ​ is ​ ​ a ​ ​ very ​ ​ strong ​ ​ and ​ ​ flexible ​ ​ material. ​ ​ There ​ ​ are ​ ​ many ​ ​ use ​ ​ cases ​ ​ where ​ ​ hard ​ ​ plastic ​ ​ is
not ​ ​ the ​ ​ ideal ​ ​ or ​ ​ even ​ ​ unusable ​ ​ at ​ ​ all. ​ ​ But ​ ​ whether ​ ​ you ​ ​ need ​ ​ a ​ ​ phone ​ ​ cover, ​ ​ an ​ ​ action ​ ​ camera
case
​ ​
or
​ ​
wheels
​ ​
for
​ ​
your
​ ​
RC
​ ​
car,
​ ​
flexible
​ ​
is
​ ​
the
​ ​
way
​ ​
to
​ ​
go.
Before ​ ​ you ​ ​ start ​ ​ printing ​ ​ from ​ ​ Flex, ​ ​ clean ​ ​ the ​ ​ nozzle ​ ​ from ​ ​ the ​ ​ previous ​ ​ material ​ ​ -
preheat
​ ​
the
​ ​
nozzle
​ ​
and
​ ​
load
​ ​
PLA
​ ​
to
​ ​
remove
​ ​
any
​ ​
other
​ ​
previous
​ ​
material.
​ ​
When
loading ​ ​ Flex, ​ ​ loosen ​ ​ the ​ ​ extruder ​ ​ (idler) ​ ​ screws. ​ ​ Keep ​ ​ in ​ ​ mind ​ ​ that ​ ​ when ​ ​ printing
from ​ ​ Flex, ​ ​ the ​ ​ automatic ​ ​ filament ​ ​ change ​ ​ function ​ ​ may ​ ​ not ​ ​ work ​ ​ properly.
Flex
​ ​ has ​ ​ very ​ ​ good ​ ​ abrasion ​ ​ resistance, ​ ​ remains ​ ​ flexible ​ ​ in ​ ​ cold ​ ​ environments, ​ ​ and ​ ​ is
resistant
​ ​
to
​ ​
many
​ ​
solvents.
​ ​
It
​ ​
doesn’t
​ ​
shrink
​ ​
much
​ ​
when
​ ​
cooling
​ ​
down,
​ ​
so
​ ​
you
​ ​
can
​ ​
be
​ ​
fairly
accurate ​ ​ with ​ ​ your ​ ​ measurements ​ ​ and ​ ​ perfect ​ ​ fit ​ ​ models.
ADVANTAGES DISADVANTAGES
Flexible ​ ​ and ​ ​ elastic Needs ​ ​ extra ​ ​ steps ​ ​ when ​ ​ loading ​ ​ filament
Little ​ ​ shrinking Can ​ ​ be ​ ​ tricky ​ ​ to ​ ​ print
Good
