GLOSSARY
Layer height The thickness of each individual deposited layer of the three-
dimensional model when cut with a slicing program.
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 its mechanical properties at elevated temperatures.
PEI Polyetherimide.
PTFE Polytetrafluoroethylene is a synthetic fluoropolymer used in the
Budaschnozzle for it’s low coefficient of friction.
RAMBo [R]epRap [A)]duino-[M]ega compatible [M]other [Bo]ard. De-
signed by Joynnyr of Ultimachine.
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.
