At a recent Go4Israel conference in Tel Aviv, a young company called Xjet introduced a new, potentially revolutionary additive manufacturing technology.
The new technology promises to remove some of the most significant barriers to the further development of 3D printing by metals, while reducing time and production costs without compromising the high detail and mechanical properties of the finished prints. The company has developed a new 3D printer, based on the world's first direct inkjet metal 3D printing system, which uses the patented Nano Metal Jetting © technology (in the last post I wrote about them nano-blackened).
By the way, Xjet was founded by two people who are the creators of Objet, one of the world's leading 3D printing companies, which has now teamed up with Stratasys to form the world's largest group of 3D printers and supplies for 3D printing, with the annual revenue of 1 billion US dollars. Xjet's CEO is Hanan Gotate, a former Objet CEO, and CTO is Dror Danai, who was vice president of sales and business development at Objet.
Traditionally, metal parts received either fur. by processing (irrationally), or by molding (hollow parts cannot be made). The new 3D metal printing technology is similar to the multi-jet PolyJet technology previously developed by Objet. Only instead of a curable resin, the printing head of the apparatus dosed spreads on a substrate a patented material - a special nanotechnological liquid metal.
This material is made on the basis of nanoparticles of certain metals (at least silver and stainless steel are already used), and is stored in a special solution, enclosed in a cartridge, which is inserted into a 3D printer developed by Xjet.
As the developers note, for each metal, the development of a specific printing process is required. The company intends to release in 2016 a 3D printer that works with liquid metal based on stainless steel nanoparticles. After this, it is planned to begin work on other liquid metals.
The ultimate goal of the company is to create liquid materials for inkjet metal 3D printing from all the basic metals used in traditional manufacturing.
