Borosilicate glass

A special glass that is resistant to thermal flucatations. This characteristic makes it ideal for use in a printer bed. Pyrex is a trade name for borosilicate glass. This glass is used in cookware and other areas requiring a material resistant to thermal changes.

Cold end

The portion of an extruder in an FFF (Fused Filament Fabrication) printer that is opposite to the hot end. This portion is normally responsible for feeding the plastic into the hot end.

Fused Filament Fabrication

Fused Filament Fabrication, an additive manufacturing process describing how material is additively deposited on to printed material to produce a sturdy object. FFF is the preferred term to use for 3D printers that use plastic extruders. This term was originated from the members of the RepRap community and its use is unconstrained legally.
