XJet’s NanoParticle Jetting™ (NPJ) technology enables the production of metal and ceramic AM parts featuring unprecedented levels of detailing, finish and accuracy, while delivering physical, geometric and operational advantages.

Key Enabler: Liquid Dispersion


The key to NPJ starts with our unique liquid dispersion methodology. Liquid suspensions containing solid nanoparticles of selected build and support materials are jetted onto the build tray to additively manufacture detailed parts. These liquid suspensions serve as the base materials for our AM process, unlike most existing metal and ceramic AM technologies that utilize hazardous and hard-to-handle powders. Our liquid suspensions are delivered and installed in hassle-free sealed cartridges.

Key Benefits

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

NPJ’s stochastic nanoparticles enable unsurpassed part quality:

  • 99.9% density
  • Isotropic uniformity
  • Extremely low shrinkage

NPJ’s ultrathin layers (composed of nanoparticles) empower virtually unlimited design flexibility:

  • Complex geometries
  • Fine details
  • Nearest net shapes
  • Smooth surfaces

NPJ’s simultaneous jetting of build and support materials in liquid suspensions delivers unrivaled operational efficiency:

  • Automated support planning
  • Easy support removal
  • Simple and safe operation

How It Works

Cartridge Loading

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

Build and support material cartridges are loaded quickly & easily by hand, eliminating the need for hard-to-handle hazardous powders.

Material Jetting

Printheads with thousands of inkjet nozzles simultaneously jet millions of ultrafine drops of both build and support materials onto the system build tray in ultrathin layers.

Liquid dispersion of solid nanoparticles in ultrathin layers enables the production of parts with virtually unlimited geometrical complexity and unrivaled quality in a highly efficient manner.

Support Removal

After the part is manufactured, the support structure, made from special support material, disintegrates easily from the finished part.

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

Final Sintering

Produced parts undergo a simple and relatively short overnight sintering process.

Easy and clean process enables smooth integration into existing operations, and short and simple post-processing.


NanoParticle Jetting™ technology enables the additive manufacturing of ceramic and metal parts using multiple materials. Leveraging our robust inkjet technology enabled by our unique liquid dispersion methodology, XJet is working to introduce a growing number of metal and ceramic build materials to anticipate evolving industry needs.
