Fused Deposition Modelling (FDM), also known as Fused Filament Fabrication (FFF) is the most common 3D printing process. Simply explained, the process involves layer by layer building with molten plastic. The material is fed into the 3D printer’s heated print head (nozzle, extruder) and melted by the high temperatures. The now liquid filament is pressed through the nozzle as an extremely fine filament. It is applied to the print bed in the XYZ direction and is used for layer-by-layer model production.
If the design consists of structures that might eventually warp, support structures are created. The support material is usually made from another plastic filament. The support construction should be removed once the print is successfully completed.
