Manual
Repetier
Host
An
open
source
slicer
program,
used
for
the
preparation
of
STL
files
prior
to
3D
printing.
Allows
manipulation
of
files
prior
to
printing;
rotating,
scaling,
and
duplication.
Resolution
The
smallest
movement
a
printer’s
extruder
can
make
within
a
single
X-Y
layer.
Often
indicates
the
produced
quality
of
a
printed
model.
Retraction
Backwards
movement
of
an
extruder
motor
to
reduce
the
amount
of
material
stringing
or
oozing.
SD
Card
A
non-volatile
memory
card
for
use
in
portable
devices
to
transfer
information,
such
as
.gcode
to
3D
printers.
Seam
The
point
at
which
two
layers
of
3D-printed
material
connect.
Shell
The
sidewalls
of
a
3D
printed
model,
created
by
the
exterior
edges
of
every
layer.

Perimeter
Shell
Thickness
The
total
width
of
an
outside
wall
of
a
3D-printed
part.
Shell
thickness
should
be
a
multiple
of
nozzle
size.
Two
shells
is
typically
best.
An
increased
number
of
shells
will
lead
to
a
stronger
model.

also
Shell
Skirt
A
platform
adhesion
option
that
extrudes
an
offset
outline
of
the
model
on
the
first
layer
of
the
print.
The
skirt
helps
to
remove
unwanted
colors
and
build
pressure
for
material
extrusion.
It
also
checks
the
accuracy
of
bed
leveling.
