Fused deposition modeling (FDM) is a 3D printing technology widely known for its speed, accuracy, and competitive cost. An FDM machine precisely extrudes melted plastic filament to create a part. Parts are very rigid, especially compared to selective laser sintering (SLS), and can be lightweighted through multiple infill options.
