Fused Deposition Modeling (FDM) 3D Printers

 

Fused Deposition Modeling (FDM), or Fused Filament Fabrication (FFF), is an additive manufacturing process that belongs to the material extrusion family. In FDM, an object is built by selectively depositing melted material in a pre-determined path, layer-by-layer. The materials used are thermoplastic polymers that come in a variety of forms.
