Fused Deposition Modeling

Fused Deposition Modeling (FDM) is a 3D printing process that uses production-grade thermoplastic material to produce prototypes and production parts. Completed parts are robust, paintable and can be sealed to be impervious to fluids. During the build process, melted plastic is deposited layer by layer to create a two-dimensional cross section of the model. This section solidifies, and the platform descends. This process is repeated until the model is complete. Similar to SLA, FDM parts require support structure, which is easily removed for most materials.
