FDM - Fused Deposition Modeling

Fused deposition modeling uses a tool that most closely resembles a miniature glue gun. In fused deposition modeling, plastic is melted in a small nozzle which puts down a very fine bead wherever the solid is supposed to be. Unfinished FDM parts have rougher surfaces than SLA parts, but typically are stronger and more durable. The parts are usually hand finished to smooth out the layered effect.

As with SLA and LOM, completed models can be used as patterns to produce “rapid tooling and castings” that can be used as functional prototypes or actual production parts.
