Multi Jet Fusion (MJF)

Get thermoplastic parts with consistent isotropic properties and excellent accuracy comparable to injection-molding quality

Cost-competitive Parts

The MJF process is cost-competitive for quickly producing low-to-medium volumes of rugged, highly detailed thermoplastic parts.

Ideal for hidden applications

Ideal for hidden applications like thin-wall ductwork, connectors, non-cosmetic housings, brackets, covers, wiring clips, guides and grommets.

Better resolution than SLS

MJF layer thickness, wall thickness, and feature resolution are all slightly better than with SLS technology

Why choose Multi Jet Fusion (MJF) Parts?

If your part requires consistent isotropic mechanical thermoplastic properties and/or complex geometries with fine features, then Multi Jet Fusion (MJF) technology may be ideal for your project

MJF parts are fabricated with chemically resistant and extremely rugged Nylon 12 powder. The MJF build process begins by spreading a very thin layer of Nylon powder on the surface of the build plate. Using high-resolution inkjet technology, fusing and detailing agents are jetted into the powder to detail the part being created. An infrared light source sinters (melts) the powder that has been inked. As it cools and solidifies, the next layer of powder is spread over it. Each layer takes 16 seconds, regardless of the number of parts being produced. Build layers are approximately 0.004″.

MJF Production Features

Multi Jet Fusion Production Parts

Production Parts

Multi Jet Fusion production parts are dense, strong, have fine detail and high dimensional accuracy.

With MJF we can produce large, custom housings with seamless fits and integration of enclosure connections.  Produce void-free, strong, water-tight or highly cosmetic parts with the right technologies and materials to deliver custom housings and enclosures to your specifications.

Multi Jet Fusion Housings


With good mechanical properties and the ability to handle complex shapes, Multi Jet Fusion parts are good for internal, non-cosmetic housings.

Whether you’re looking for void-free, strong, water-tight or highly cosmetic parts, we have the right technologies and materials to deliver custom housings and enclosures to your specifications. Specializing in assembly and fit check, we can guarantee perfect seam alignments from the smallest components to large panels.

Multi Jet Fusion Prototype

Functional Prototyping

Multi Jet Fusion is an ideal technology for complex components needed in functional prototyping.

Prove and perfect your designs in rigorous testing scenarios with tough 3D printed prototypes. With a range of technologies and engineering-grade materials to choose from, you can reveal how your product performs before market production.
