GLOSSARY
Heater resistor
A special type of resistor that is used to apply heat in a
small area.
HIPS High Impact Polystyrene.
Hot end
The hot end is the whole part where the plastic melts, including
the nozzle, heater block, thermistor, and heat sink. The Budaschnozzle is
LulzBot’s
TM
hot end.
Idler
Refers to parts using a bearing (usually a 608ZZ) to add tension in
belts or to add pressure against a rolling surface.
Layer height
The thickness of each individual deposited layer of the three
dimensional model when cut with a slicing program.
Laywoo-D3
Wooden filament similar to PLA. Contains 40 percent recycled
wood. Usually prints at 180C- 210C. Color can be changed by varying the
extrusion temperature.
Nozzle
The metal tip at the bottom of the hot end. It has a small hole
where the plastic filament comes out of the printer.
PEEK
Polyether ether ketone- an organic polymer used to insulate the hot
end due to it’s mechanical properties at elevated temperatures.
PET Polyethylene terephthalate.
PLA
Polylactic Acid is a corn-based biodegradable polymer. Usually extrudes
at 185C.
Polycarbonate
A strong and impact resistant thermoplastic. Usually
extrudes at 300C.
RAMBo
[R]epRap [A)]duino-[M]ega compatible [M]other [Bo]ard. Designed
by Joynnyr of Ultimachine.
Spool
Plastic Filament coiled and stored on a plastic reel. Preferred due to
improved feeding and better mounting options.
STL
Stereolithography file, also known as Standard Tessellation Language,
and STL file is the common 3D model file format.
Thermistor
A special type of resistor that changes resistance based on
temperature. It is used to measure temperature on the nozzle and the heated
bed.
Threaded extension
Used to separate the heater block and nozzle from the
PEEK insulator. The plastic filament passes through the threaded extension
into the melting chamber.
