XJet Ltd. unveiled a new ceramic material, alumina, at formnext. Alumina was chosen because of its wide use as a technical ceramic and market demand to see parts produced with XJet NanoParticle Jetting (NPJ) production. Offering very good electrical insulation, extremely high mechanical strength, high compressive strength and high hardness, it differs from zirconia in that it has lower wear resistance, making it simple to machine and refine both before and after firing.
XJet also announced its entry into Italy with a new Carmel 1400 AM System to be installed at Beam-IT, Italy’s largest additive manufacturing bureau, before the end of the year. The latest order represents the growth of XJet’s presence to seven countries across the globe.
The recent opening of XJet’s more than $10m Additive Manufacturing Centre helped develop this material, noted XJet CEO Hanan Gothait. The facility is dedicated to the development of new materials and applications in metal and ceramic AM. The new alumina material devolpment was sped up thanks to the availability of dedicated systems for the purpose. XJet engineers are examining every part of the process for opportunities to push the envelope, from the hardware, the material chemistry and beyond.
According to Gothait one such development has been in the support materials. Overhangs and cavities are supported throughout the NPJ build process by a soluble support material, which has recently been created to fit the soon-to-be-available stainless steel material. Fine detail and complex geometries can be created with no concern they will be harmed in the bath support-removal process.
