Nuburu was awarded a U.S. patent for blue laser applications of welding copper material and its alloys. This new patent is part of an additional seven patents that range across 3-D printing and material processing. “This new patent covers all forms of 3-D printing, welding and methods of opening up the keyhole using blue laser light,” said Mark Zediker, founder and chairman of Nuburu. Blue lasers provide greater speed and quality control for metal processing operations, such as welding and additive manufacturing. They leverage a fundamental physical advantage to produce defect-free welds up to 10 times faster than traditional approaches.
