Nuburu awarded US patent for copper welding with blue laser

05 Apr 2021

Expands firm's IP portfolio, covers all potential apps of copper welding in automotive and e-mobility.

Nuburu, a developer of high power, blue laser technology, has been awarded a US patent covering copper welding with blue laser; Patent 10,940,562 is for blue laser applications of welding copper material and its alloys.

The patent joins Nuburu’s IP portfolio that grew substantially in January 2021 with the addition of seven patents across 3D printing and material processing. The firm’s foundational patent, “3D printing Devices and Methods” PCT/US14/35928, was awarded in 16 countries.

“This new patent covers all forms of 3D printing, welding, and methods of opening up the keyhole using blue laser light,” commented Dr. Mark Zediker, Founder and Chairman of Nuburu.

Multiple processing patents

“It is a core addition to the broad list of 34 patents we have already been awarded. Our IP portfolio widely covers blue laser technology, multimode and single mode as well as broad applications within 3D printing and material processing, and we have an additional 79 pending patent applications, signaling the possibility for even further expansion of our portfolio.”

Nuburu’s blue lasers provide unprecedented speed and quality control for metal processing operations, such as welding and additive manufacturing, particularly in growing industries like e-mobility and automotive.

In these industrial applications, copper materials, stainless steel and aluminum are increasingly critical, and existing market technologies do not have the flexibility, speed or power to produce high-quality results. The Centennial, CO-based company’s industrial blue lasers are said to “leverage a fundamental physical advantage to produce defect-free welds up to ten times faster than the traditional approaches — all with the flexibility inherent to laser processing.”

Guy Gilliland, CEO, said, “Our growing IP portfolio provides strong protection for our technical superiority. We have expanded the reach of our capabilities and increase our intellectual property portfolio, further securing our market potential and ability to serve customers across industries.”
