Welcome to the new era of digital manufacturing!! We are capable of manufacturing 130-600 (size depended) functional PA12 parts with isotropic mechanical properties that can be used for detailed prototyping or end-use low volume production.Multi Jet Fusion is a powder based 3D printing technology which offers much more possibilities in digital manufacturing for complex and low cost parts. It uses a fine-grained PA12 powder material that allows for ultra-thin layers of 80 microns. HP Multi Jet Fusion technology gives the freedom to iterate and test various designs and create faster, cheaper, and more lightweight products like gauges, models, sports performance eyewear, helmets, and trophies.

How does Multi Jet Fusion Work?

Multi Jet Fusion is a powder-based technology that 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.

The 3D Model

A fusing agent and a detailing agent are jetted to selectively melt powder particles and improve resolution

Lamps pass over the surface constantly, the jetted materials captures and distributes the heat

The process continues building up the part layer by layer

The loose powder is removed

The part is finished


Engineering-grade thermoplastic, optimized for 3D printing efficiency.

  • The PA12 is a strong thermoplastic material well-suited for high-volume functional prototyping and low-volume production applications.
  • It also leads to an exceptionally smooth surface straight out of the printer, hence functional parts and complex thin structures, only need minimal post-production finishing.
  • That means short lead times, ideal for functional prototypes and small series of end-parts.
  • Certified by UL according to the UL94 standard for safety of flammability of plastic materials for parts in devices and appliances testing and the UL 746A standard for polymeric materials to measure short term property evaluations.
