Polyamide 3D printing,
without the lasers
HP spread waves of excitement throughout the 3D printing world with the announcement of the Multi Jet Fusion (MJF) technology. Discover the new technology that is ideal for when you need short lead times, low porosity and excellent surface quality, for functional prototypes and small series.
Why choose Multi Jet Fusion?
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 applications for Multi Jet Fusion
- Low-volume production of complex end-use parts
- Prototypes for form, fit and function testing
- Prototypes with mechanical properties to rival those of injection-molded parts
- Series of small components as a cost-effective alternative to injection molding

How Does Multi Jet Fusion Work?
Multi Jet Fusion is a powder-based technology but does not use lasers. The powder bed is heated uniformly at the outset. A fusing agent is jetted where particles need to be selectively molten, and a detailing agent is jetted around the contours to improve part resolution. While lamps pass over the surface of the powder bed, the jetted material captures the heat and helps distribute it evenly.
