NUBURU awarded patent for copper welding with blue light
NUBURU Inc of Centennial, CO, USA (which was founded in 2015 and develops and manufactures high-power, high-brightness industrial blue lasers) has been awarded US patent no. 10,940,562 (for blue laser applications of welding copper material and its alloys) by the US Patent Office.
NUBURU’s IP portfolio previously grew in January 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, with several other applications and continuations pending around the world, including with the US Patent Office (2016/0067780).
“This new patent covers all forms of 3D printing, welding, and methods of opening up the keyhole using blue laser light,” says founder & chairman Dr Mark Zediker. “It is a core addition to the broad list of 34 patents NUBURU has already been awarded,” he adds. “Our IP portfolio widely covers blue laser technology, multi-mode 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 says that its blue lasers provide speed and quality control for metal processing operations, such as welding and additive manufacturing, particularly in growing industries like e-mobility and automotive, where copper materials, stainless steel and aluminium are increasingly critical, and existing market technologies do not have the flexibility, speed or power to produce high-quality results. The firm says that its industrial blue lasers 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.
“We’ve taken great strides in just a few months to expand the reach of our capabilities and increase our intellectual property portfolio, further securing our market potential and ability to serve customers across industries,” comments CEO Guy Gilliland.
