Additive Manufacturing – NanoParticle Jetting (NPJ) Technology:

NanoParticle Jetting technology produces high strength metal parts with the ease and versatility of the Inkjet based additive manufacturing. The technology is based on enabling metal to be deposited in liquid form so it can be jetted from standard inkjet nozzles, to do this, the system uses nano sized metal particles suspended within special liquid formula eliminating inefficient lasers, this metal liquid formula can be jetted from standard printing head. The material are packaged with specially adapted cartridges that are loaded easily by hand into the system.

Because there is no powder VAT, the system uses only the material that you need saving space and eliminating the need to handle metal powders.
​
The print heads deposit a fine layer of metal liquid droplets onto the system build tray, with each pass of the print heads the metal part is built up as the tray descends the metal liquid formula which is jetted from many thousands of printing nozzles synchronously in a process that is up to five times faster than laser metal printer. Within the system build enveloped, a temperature of up to 550 degrees Fahrenheit or 300 degrees Celsius cause the liquid jacket around the metal nanoparticles to elaborate allowing the stochastic metal particles to bind strongly and with virtually the same metallic and density as traditional made metal parts. With layer thickness under 2 microns, the result is never before seen levels of detailed surface finish and accuracy with no compromise on speed or build time.
