ACTIVE COOLING FAN: The fan that
cools the MakerBot PLA Filament as
it extrudes.
BUILD PLATE: The surface on which the
MakerBot Replicator 2 makes an object.
BUILD PLATFORM: The support for the
build plate. The build platform includes
knobs for manual leveling.
PLUNGER: A part of the extruder
assembly. The Delrin plunger pushes the
MakerBot PLA Filament against
the drive gear.
DRIVE GEAR: The gear that drives the
MakerBot PLA Filament into the heater.
EXTRUDER: Draws MakerBot PLA
Filament from the spool and pushes it
into the nozzle, where it is heated and
squeezed onto the build plate
EXTRUDER FAN: The fan that keeps the
MakerBot Replicator 2 motor cool and
disperses heat from the heat sink.
FAN GUARD: A grill that protects the
extruder fan and protects the user
from the fan.
FILAMENT GUIDE TUBE: A plastic tube
that guides the MakerBot PLA Filament
from the filament spool to the extruder.
GCODE: A computer language used to
describe the toolpath your MakerBot
Replicator 2 will use to build an object.
GCode is converted to S3G before being
sent to your machine.
HEAT SINK: An active heat sink that
dissipates heat from the cartridge heater.
It looks like an aluminum plate with fins.
LCD CONTROL PANEL: The liquid-
crystal display in the front lower right
corner of the MakerBot Replicator 2. This
control panel provides status information
about the MakerBot Replicator 2 and
includes control menus and diagnostics.
MAKERBOT PLA FILAMENT: Polylactic
acid filament. PLA is a renewable
bioplastic. MakerBot PLA Filament is the
source material from which you make
objects on the MakerBot Replicator 2.
MAKERBOT REPLICATOR 2: The
MakerBot Replicator 2 Desktop 3D Printer.
MAKERWARE: Free soware created
by MakerBot that allows you to load 3D
model files, manipulate and edit those
files, and send them to the MakerBot
Replicator 2 for building.
MOTOR ASSEMBLY: The stepper motor
and the drive block that push filament
into the extruder.
