Fused deposition modeling

Which 3D printing technology will 'win' in the market, or are different approaches going to find specific uses. Here's one way: fused deposition modeling. Durable, accurate, parts ... from your desktop. Slice the STL files and generate 3D support structure and extrusion paths. Solid material (thermoplastic) in filament form is heated to a less viscous state for extrusion. The model is built layer by layer, from the bottom up. Soluble supports are simply dissolved in a water based solution resulting in a part with smooth surface finish and fine detail in tact.
