[Fused filament fabrication](https://en.wikipedia.org/wiki/Fused_filament_fabrication) (FFF), also known as Fused Deposition Modeling (FDM) is a 3D printing process that uses a continuous filament of a thermoplastic material.
Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work.
The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer.
The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal layer at a time; the job of the print bed is then to move vertically a certain distance to start a new layer.
