Raft: Layer of plastic mesh which is well adhered to the printing surface upon which a model is built.

Platform: The surface a 3D model is built upon. For the UP 3D printer, the platform moves on all 3 axes for printing while the nozzle remains stationary.

Nozzle: The heated print head which liquefies the plastic filament and deposits it upon the model during the addditive layering process.

Filament: The thin plastic which is fed into the heated nozzle and which is the raw material out of which a 3D model is created.

Perfboard: The top most surface of the printing platform. This is perforated and heated to improve adhesion of the filament in order to improve accuracy of the reproduction.

Extrusion: The process of forcing a molten substance through a die or form, in this case, the nozzle.

ABS: One of the most common types of plastic used for 3D printing.

Scale: To resize proportionally.

Additive Manufacturing: Any manufacturing process which adds material to a product, building it up, rather than removing product to produce the final result. This is the opposite of milling.
