Desktop Metal awarded patents for its metal 3D printing technology


Desktop Metal, Inc, based in Burlington, Massachusetts, has been granted seminal patents by the United States Patent and Trademark Office for its inventions in interface layer technology for both its Studio System and Production System 3D printers.

The patents (US Patent No. 9,815,118 and US Patent No. 9,833,839) cover the separable support layer technology used in Desktop Metal’s Studio System, which began shipping in December 2017, and in its Production System, which is scheduled to begin shipping in late 2018. The technology is an industry first that enables printing of large parts through metal sintering and the removal of metal support structures by hand.

“The technological innovation in these patents enables users, for the first time, to print large metal parts with complex geometries that can be easily removed from their support structures by hand or to print metal objects with separable interlocking structures,” said Jonah Myerberg, chief technology officer and co-founder of Desktop Metal.

“Traditional laser powder bed methods for metal additive manufacturing (AM) are restricted to single materials and are both difficult and costly to implement,” added Myerberg. “Desktop Metal has designed new approaches for metal AM that now allows multiple materials to be used during printing. This makes it possible to print support structures that do not bond to parts and consolidate during sintering with the part and, as a result, high dimensional accuracy is achieved, and support structures are easily removed by hand.”
