Sandvik prints diamonds with stereolithography

This super-hard material can be 3D printed in highly complex shapes and can revolutionize the way industry uses the hardest natural material on the planet.

By using additive manufacturing, Sandvik has managed to 3D-print diamond composites which can be formed in almost any shape. This opens the possibility of using it in applications that were previously considered impossible.

“We now have the ability to create strong diamond composites in very complex shapes through additive manufacturing, which fundamentally will change the way industries will be able to use this material. As of now, the only limit to how this super-hard material can be shaped and used is down to the designer’s imagination,” says Mikael Schuisky, Head of R&D and Operations at Sandvik Additive Manufacturing.

The diamond composite has been tested and found to have extremely high hardness, exceptional heat conductivity, while also possessing low density, very good thermal expansion and fantastic corrosion resistance. It was unveiled at the RAPID + TCT show in Detroit May 21 - 23, 2019, North America’s leading event for Additive Manufacturing.
