Fused Deposition Modeling

FDM is a process where filament is pushed into a hot extruder. The filament is heated first and then deposited, through the nozzle, onto a build platform in a layer-by-layer process to form a solid part. This process is useful for low cost/high strength prototypes or fixturing.
