Currently the fastest technology in the industry. Flexible parts are possible and may be built in different colors. Accuracy, surface finish, and material strength make the process best suited for concept models. FDM Fused deposition modeling uses a heated extrusion tip to melt materials in filament form. A variety of office-friendly materials are available, including ABS, wax, and elastomer.
Some newer machines offer water-soluble supports.
Detectable layering requires finishing. Inkjet Similar to conventional inkjet printing technology using a photopolymer. Addition of an elevator enables the third axis of printing. Can provide exceptional speed and accuracy with surface finishes that require only light finishing when you paint the part. Limited proprietary material selection.
