 +====== Glossary of 3D Printing and Printer Terms ======
 +This is a list of common terms and abbreviations used in the 3D printer, design, and printing communities. ​
 +==== ABS ====
 +  * Abbreviation for [[wp>​Acrylonitrile_butadiene_styrene|Acrylonitrile Butadiene Styrene]], which is a thermoplastic used in build materials.
 +  * ABS is often used when referring to filament made of ABS.
 +==== Bed ====
 +  * The build plate of the 3D printer on which parts are actually made.
 +==== Extruder ====
 +  * A group of parts which handles feeding and extruding of the build material.
 +  * Each extruder consists of two assemblies; a cold end to pull and feed the filament from the spool, and a hot end that melts and extrudes the filament.
 +==== Filament ====
 +  * Plastic material that is formed into string, which is then used as build material in 3D printers.
 +  * Typical filament diameters are 1.75mm and 3mm.
 +==== OBJ ====
 +  * Abbreviation for [[wp>​Wavefront_.obj_file|Object File]], which an alternative file format to describe 3D objects. See STL.
 +==== PLA ====
 +  * Abbreviation for [[wp>​Polylactic_acid|Polylactic Acid]], which is a biodegradable thermoplastic polymer that is used as build material.
 +  * PLA is often used when referring to filament made of PLA.
 +==== PVA ====
 +  * Abbreviation for [[wp>​Polyvinyl_alcohol|Polyvinyl Alcohol]], which is a water soluble filament used as build material.
 +  * PVA is often used when referring to filament made of PVA.
 +  * PVA is soluble in water, and mainly used for support material. ​
 +==== STL ====
 +  * Abbreviation for [[wp>​STL_(file_format)|Stereo Lithographic]],​ which is a recommended file format to describe 3D objects.
 +  * 3D designs are converted into an STL files, which are then used to print parts on 3D printers.
 +==== Support Material ====
 +  * Extra (non-design related) material that acts as support while printing overhangs, arches, etc.
 +  * The material can either be the primary material that is broken away at the end of the print, **or** a secondary material (such as PVA) that can be removed using another process.
