View source for Fused Filament Fabrication (FFF)

==Overview==
This is the most common type of 3D printing technology today. It's basically a robotic hot glue gun that builds objects layer-by-layer. 

==How it Works==
Plastic [[Filament]] is fed by gears through a heated area, where it is then squeezed through a nozzle and applied layer-by-layer onto a flat surface.
