Shell
Thickness
This
defines
the
number
of
vertical
walls
that
comprise
the
outside
of
your
model.
We
recommend
keeping
this
set
to
multiples
of
your
nozzle
width.
Your
Mini
3D
printer
is
equipped
with
0.4mm
nozzle.
Enable
Retraction
Retraction
tells
your
printer
to
pull
filament
out
of
the
hot
end
upon
travel
moves.
Travel
moves
are
when
your
head
moves
from
one
area
of
the
print,
to
another
without
laying
down
filament.
We
recommend
keeping
this
on
for
all
filament
types,
and
adjusting
the
retraction
length
and
speed
for
the
specific
filament.
Bottom/Top
Thickness(mm)
Also
know
as
"
Surface
Layers
",
this
will
determine
how
thick
the
top
and
bottom
layers
are.
A
larger
number
here
will
create
a
thicker
top
and
bottom
which
can
be
helpful
for
strength,
bridging,
and
quality
purposes.
We
recommend
keeping
this
number
as
a
multiple
of
your
layer
height.
Fill
Density
This
number
is
expressed
as
a
percentage.
0%
will
give
a
completely
hollow
print,
while
100%
will
give
you
a
completely
solid
object.
We
have
found
that
20%
to
40%
fill
density
is
functional
for
most
prints.
