Extruder Fan Baffle A plastic piece that directs air from the extruder fan onto the build plate to assist in
cooling the active build.
Extruder Intake An opening located at the top of the extruder where filament is inserted for building.
Extruder Lever A lever located on the side of the extruder that is used to loosen the grip of the
extruder gear motor.
Extruder Tip A nozzle located at the bottom of the extruder where heated filament is forced out for
building.
Filament A threadlike strand of plastic material.
Filament Guide Tube A plastic piece that guides the filament from the filament spool through a passage in
the outer housing of your Dremel 3D40.
Filament Jam Sensor A sensor in the extruder that pauses your printer if filament stops extruding properly.
Filament Runout Sensor A sensor in the extruder intake that pauses your printer if it runs out of filament
during a build.
Filament Spool A cylindrical piece on which a long strand of filament is wound for storage and
continuous use.
.g, .gcode, .g3drem A buildable file format compatible with your Dremel 3D40.
Leveling Knobs Knobs located under the build platform base that are used to create proper spacing
between the extruder tip and the build plate.
Leveling Sensor A sensor that detects the height of the build platform and assists in proper leveling.
Lid Your Dremel 3D40 has a pivoting lid on the top. This allows for more access to the
build plate, extruder, filament, and objects when necessary.
Needle Nose Pliers Common tool used to hold small objects and to grab excess material that may be too
hot to touch directly.
OBJ File A common digital file format used in a wide range of 3D model software. This file is
created in 3rd party 3D software or downloaded.
Object Removal Tool A tool used to separate your objects from the build plate.
PLA A bioplastic derived from renewable resources such as corn starch.
Spool Holder A plastic piece located to the left of the build plate inside your Dremel 3D40 build area
that is designed to hold a filament spool.
Spool Door A removable door which locks the filament spool to the spool holder.
Stepper Motor A brushless DC electric motor used to drive the guide rails and extruder gears.
.STL File A common digital file format used in a wide range of 3D model software. This file is
created in 3rd party 3D software or downloaded.
Touch Screen Full color display that is touch activated. It allows you to monitor your Dremel 3D40
and objects while also providing commands directly to your Dremel 3D40 without the
use of a computer.
USB Flash Drive A portable memory card used on a wide array of devices.
