Whether you’re a startup looking to launch your first product or an established company seeking to streamline your development process, our rapid prototyping solutions are designed to meet your needs.

What is Multi Jet Fusion?

Multi Jet Fusion is an industrial 3D printing process that produces functional nylon prototypes and end-use production parts in as fast as 1 day. Final parts exhibit quality surface finishes, fine feature resolution, and ‬more consistent mechanical properties when compared to processes like selective laser sintering.

Common applications for Multi Jet Fusion are:

  • parts requiring consistent isotropic mechanical properties

  • functional prototypes and end-use parts

  • complex and organic geometries with fine features

Multi Jet Fusion selectively applies fusing and detailing agents across a bed of nylon powder, which are fused in thousands of layers by heating elements into a solid functional component.

*General Material Selection available through our external Manufacturing Suppliers.

  • PA 12 Black is a high tensile strength nylon. Final parts are dyed black, and they exhibit quality surface finishes and slightly more isotropic mechanical properties when compared to SLS. When more detail is required, PA 12 can achieve smaller minimum feature resolution (0.02 in) as compared to SLS materials (0.03 in). PA 12 Black is the best material option for designs that incorporate living hinges.

    Primary Benefits​

    • Near isotropic mechanical properties

    • Economical material choice

  • PA 12 40% Glass-Filled Black is a 40% glass-filled nylon. Final parts are dyed black. The biggest advantage offered by this material is heat deflection at 347°F (measured at 66 psi), ranking 2nd best after PA 12 Mineral-Filled.

    Primary Benefits​

    • Economical material choice

    • Heat deflection  

Post-Processing Capabilities for Multi Jet Fusion Surface Finish

Standard A bead blast removes all powder and leaves a consistent overall texture. Parts are then dyed a standard black color.

Vapor Smoothing Significant reduction of surface roughness from 250+ μin RA (as-printed) to 64 – 100 μin RA after smoothing. Available for PA12 Black.

CustomSecondary options include a primer that can be applied as well as taps and inserts.
