Nuburu, provider of in high power blue laser technology, has been awarded seven new patents, further demonstrating its dominant intellectual property portfolio in visible laser technology and its applications across 3D printing and material processing.

The company in Colorado was awarded four US Patents, one in Russia, Japan, and Korea, respectively, all joining the foundational patent ‘3D printing Devices and Methods’ which was awarded in 16 countries with several other applications and continuations pending around the world, including with the US patent office.

These latest patents range from, ‘Material Processing with Visible Raman Laser’, to the technology required to build these unique single mode visible lasers. Nuburu has also received several notices of allowances inclusive of the technology and the application of blue lasers to material processing and 3D printing.

“Our IP portfolio is broad and deep,” said CEO Dr Guy Gilliland. “Industry analysts and organizations have recognized the strength of our technology and its IP portfolio, including StartUp Insight, who identified us as one of the ‘Top 5 Additive Manufacturing Start Ups Impacting the Automotive Industry’.”

The company’s blue lasers provide a great deal of speed and quality control for metal processing operations, such as welding and additive manufacturing in a variety of growing industries like e-mobility and automotive, where materials such as copper, stainless steel and aluminum are increasingly critical. Previous technologies were more inflexible, slow and produced poor-quality metal joints, but Nuburu’s industrial blue lasers leverage a fundamental physical advantage to promise defect-free welds up to four times faster than the traditional approaches – all with the flexibility inherent to laser processing.

“These patents firmly establish that Nuburu invented the blue laser technology for 3D printing and material processing,” said Dr Mark Zediker, Nuburu founder and chairman. “The company portfolio widely covers blue laser technology, multimode and single-mode as well as broad applications within 3D printing and material processing. 22 patents have been awarded to date, with 90 applications currently in process for a number of claims in excess of 4,000.” (Source: Nuburu)
