PLA
Polylactic Acid (PLA) is a biodegradable thermoplastic polymer derived from the
starch in plants (normally corn) that is used for 3D printing.
Perimeter
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.

Build Plate
Print Speed
The rate at which a 3D printer is capable of moving while extruding plastic. A
print speed of 50mm/s will be successful on most FDM printers. A print speed of
20–30mm/s will produce higher quality prints.
Print Quality
Refers to the quality of the print and is determined by many factors including
mechanical capabilities of the printer, slicer used, layer height, print speed,
support, and print 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 print dissolvable supports.
