Parts featuring unprecedented levels of detail and accuracy. Physical, geometric and operational advantages. XJ3D’s NanoParticle Jetting™ (NPJ) technology heralds the dawn of a new age in metal and ceramic additive manufacturing.

Liquid Dispersion: Making the impossible possible

The key to NPJ is a unique liquid dispersion methodology, where liquid suspensions containing solid nanoparticles of build and support materials are jetted onto the tray to create the required parts. Delivered and installed in hassle-free sealed cartridges, these liquid suspensions serve as the base materials for our additive manufacturing process, unlike most existing metal and ceramic AM technologies that utilise hazardous and difficult-to-handle powders.

Key benefits

Leveraging NPJ’s key features of stochastic nanoparticles, ultra-thin layers and simultaneous jetting, XJ3D delivers on the additive manufacturing promise by creating “complexity free” high-quality parts with virtually unlimited geometries, in an operationally efficient manner.

How it works

1 Cartridge Loading

Process: Solid nanoparticles in a liquid suspension are delivered within convenient sealed cartridges.

Advantage: Cartridges are loaded quickly and easily by hand, eliminating the need for hard-to-handle hazardous powders.

2 Material Jetting

Process: Printheads with thousands of inkjet nozzles simultaneously jet millions of ultra-fine drops of build and support materials onto the tray, in ultra-thin layers.

Advantage: This unique liquid dispersion technique enables the production of parts with virtually unlimited geometrical complexity and unrivalled quality, with ultimate efficiency.

3 Support Removal

Process: After a part is manufactured, the support structure - made from special support material - disintegrates easily from the finished article.

Advantage: Support materials are removed easily without harming the part, greatly reducing the need for delicate and time-consuming post-processing.

4 Final Sintering

Process: Parts undergo a simple and relatively short overnight sintering process.

Advantage: This easy and clean process enables smooth integration into existing business operations, with hassle-free post-processing.


NanoParticle Jetting™ systems enable the additive manufacturing of ceramic and metal parts using multiple materials. Through a combination of robust inkjet technology and a ground-breaking liquid dispersion technique, XJ3D is working to introduce a growing number of build materials to anticipate the demands of the future.
