Fused Deposition Modeling (FDM)

Fused Deposition Modeling  (FDM) is a rapid prototyping process used to produce functional ABS thermoplastic models directly from CAD data . The system utilizes a CNC controlled extruder-head which squeezes a fine filament of melted thermoplastic through a nozzle. The nozzle deposits the heated plastic layer-by-layer to form the desired shape. The liquid material hardens immediately on contact in the cooler environment. The system consists of a build platform, extrusion nozzle, and control system.

The build material, production quality termoplastics, is melted and then extruded through a specially designed head onto a platform to create a two-dimensional cross section of the model. The cross section quickly solidifies, and the platform descends where the next layer is extruded upon the previous layer. This continues until the model is complete, where it is then removed  from the build chamber and cleaned for shipping.

FDM Highlights

• Ideal for conceptual models, Engineering models, and Functional Testing Prototypes.

• Material Choices include production-quality ABS (black and white). Custom colors available.

• Dimensional tolerances are +/- 0.005" for the first inch, and +/- 0.002" for each additional inch. In z height (vertical), standard tolerances of +/- 0.01" for the first inch, +/- 0.002" on every inch thereafter.

• Layer thickness: Standard Resolution: 0.01"; Minimum wall thickness is 0.050".

• Build Envelope: 8(X) X 8(Y) X 12(Z, vertical).
