XJet unveils new ceramic material for its 3D printers

XJet's Carmel 1400 AM system for ceramic parts.

XJet Ltd., a provider of solutions for metal and ceramic additive manufacturing applications, recently began offering a new ceramic material ─ alumina.

The company, based in Rehovot, Israel, said alumina was chosen for development because of its wide use as a technical ceramic and “market demand to see parts produced with the benefits of XJet’s NanoParticle Jetting™ (NPJ)” technology. Alumina offers good electrical insulation, extremely high mechanical strength, high compressive strength, and high hardness. It also resists wear better than zirconia, making it simple to machine and refine before and after firing.

A distinguishing characteristic of NPJ technology is that it relies on liquid-dispersion technology, not powder-bed. This provides benefits in terms of the mechanical properties of materials and geometric properties of parts, reports XJet. It also offers operational and safety advantages, because the technology eliminates high-energy lasers and fine metal powders. XJet materials are contained in enclosed, replaceable cartridges.
