Fused Deposition Modeling (FDM)

Fused Deposition Modeling (FDM) is a solid-based rapid prototyping method that extrudes material, layer-by-layer, to build a model. The system consists of a build platform, extrusion nozzle, and control system.

The build material, a production quality thermoplastic, 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.
  • Maximum dimensions for instant quotes: 20"x20"x20". Parts with larger dimensions are also available. Please contact your sales manager to discuss.
  • Maximum dimensions for parts in single build: ABS - 23"x19"x23", Polycarbonate (PC) - 14"x16"x16". Parts with larger dimensions are also available. Please contact your sales manager to discuss.
  • Material choices include: production-quality ABS (red, yellow, green, blue, gray, steel gray, white, and black), ABS-M30 (white, red, blue, and gray), Polycarbonate (white), PC-ABS (black), PC-ISO (white and translucent), ULTEM, and PPSF (tan). Food-grade ABSi material available upon request.
  • Dimensional tolerances are: +/- 0.005" for the first inch, and +/- 0.002" for each additional inch. In the 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 0.02”.
