»We’re talking about nanometers«
by Thomas Masuch
If there had been an award at formnext 2017 for the exhibitor who most passionately marketed their product, Dror Danai definitely would have been shortlisted.
The Chief Business Officer of XJet worked the booth with great professionalism, showcasing one of the exhibition’s key innovations: the Carmel 1400. The Israeli company XJet had already displayed its precursor version in 2016. The first machine to be shipped is now in use at Oerlikon AM in Magdeburg, Germany. And Dror proudly pointed out that all ceramic sample parts at the booth, were manufactured in Magdeburg. It was an Israeli-German co-production, so to speak.
XJet consciously decided to make Germany the location of the first machine, viewing the Central European market as key.
Dror took great pleasure in reporting the exact resolution of the Carmel 1400: »We’re no longer talking about microns here, we’re talking about nanometers.« To underline this, XJet dubbed the production technology of the Carmel 1400 »nano jetting«. Dror also had plenty of figures to hand at his booth. The precision of the XJet development reaches 10 nanometers with silver and less than 100 nanometers with ceramics. According to Dror, the industry particle diameter norm in metals had been around 50 microns, so on average its 100 times thinner.
To reach this new level of precision, XJet has devised a very sophisticated process in which the finest droplets of a dispersion are used to »print«. The Carmel applies 220 million droplets per second. The water from the dispersion evaporates in a split second on the 200–300°C building board. The remaining nanoparticles stick, forming a green body that then needs to be sintered. XJet promises not only high precision but also an extraordinary component density of 99.91%. At the same time, component costs are sinking, Dror said. »This will make ceramic components so economical that we can develop completely new applications with them.«
Founded in Israel in 2006, the company continues to grow. There are currently 85 employees, and this number is increasing recently by more than one a week on average.
