Manual
A
continuous
line
forming
the
boundary
of
a
closed
geometric
figure.
In
3D
printing,
the
perimeter
is
created
by
the
edges
of
every
layer.

Shell
Preheat
Heating
prior
to
using
the
device
or
tool.
In
3D
printing,
the
nozzle
needs
to
be
preheated
before
printing
or
for
loading
and
unloading
filament.
Print
Bed
The
surface
where
the
printer
deposits
the
materials
used
for
printing.
Also
known
as
the
build
plate.

Print
Speed
The
rate
at
which
a
3D
printer
is
capable
of
moving
while
extruding
plastic.
A
speed
of
50mm/s
will
be
successful
on
most
FDM
printers.
A
speed
of
20–30mm/s
will
produce
higher
quality
prints.
Print
Quality
Refers
to
the
quality
of
the
and
is
determined
by
many
factors
including
mechanical
capabilities
of
the
printer,
slicer
used,
layer
height,
speed,
support,
and
orientation.
Printing
Temperature
The
temperature
of
the
hot
end
at
which
the
filament
is
melted
and
extruded.
PVA
Polyvinyl
Alcohol
(PVA)
is
a
water
soluble
plastic
that
is
a
common
ingredient
in
standard
wood
glue.
It
can
be
used
in
3D
printing
to
dissolvable
supports.
Raft
A
platform
adhesion
option
in
which
several
layers
of
printed
material
are
deposited
on
the
build
surface
to
smooth
out
any
irregularities
in
the
build
surface
and
help
prevent
warping
in
the
model
being
printed
on
top
of
the
raft.
A
raft
also
helps
with
bed
adhesion
of
delicate
models.
RepRap
An
open
source
3D
printing
project,
started
in
2005,
to
create
the
best
desktop
printers
and
to
make
them
capable
of
duplicating
themselves.
