Multi Jet Fusion (MJF)
At a Glance
About the Process
Multi Jet Fusion is a new 3D printing technology, offering you more possibilities for complex, lower-cost parts. Whether used in serial production for single parts or batch manufacturing by shipsets of multiple part numbers, Multi Jet Fusion offers a faster, more cost-effective process for 3D printed parts.
Multi Jet Fusion is ideal for hidden applications like complex thin-wall ductwork, connectors, non-cosmetic housings, brackets, covers, wiring clips, guides and grommets.
Multi Jet Fusion uses a fine-grained PA 12 material that allows for ultra-thin layers of 80 microns. This leads to parts with high density and low porosity, compared to PA 12 parts produced with Laser Sintering.
It also leads to an exceptionally smooth surface straight out of the printer, and functional parts need minimal post-production finishing. That means short lead times, ideal for functional prototypes and small series of end-parts.

Ideal MJF applications
Our in-house manufacturing experts recommend using MJF for the following use cases.
MJF is ideal for fabricating functional prototypes from durable, chemically resistant engineering thermoplastics.
Appearance: Smooth surface
Quantity: 1-5 parts
MJF is cost-competitive to injection molding for low-volume manufacturing of end-use plastics parts for quantities up to 300 units.
Appearance: Injection molding-like
Quantity: 10-300 parts
Additional post processes can be applied to improve the appearance or mechanical properties of parts produced with MJF.
As printed MJF parts are typically grey in color and have a smooth surface, without visible layers, and a powder texture.
MJF parts are dyed black by immersing in a warm color bath. The color penetration reaches an approximate depth of 0.5 mm and covers all surfaces.
