Nuburu awarded eight new patents across 3D printing and materials processing
Blue diode laser manufacturer Nuburu has strengthened its IP portfolio with the awarding of eight new patents.
The patents offer broad coverage for using a visible Raman laser below 800nm in additive manufacturing and welding applications, as well as the technology required to build these single-mode lasers.
In addition, the most recent patent covers the use of blue laser diodes in a matrix to print a part in a powder bed.
Blue lasers provide increased speed and quality control when processing reflective materials such as copper, stainless steel and aluminium, in applications such as welding and additive manufacturing. The technology is gaining increasing interest in the field of e-mobility, where copper components are used in both the batteries and motors of electric vehicles.
The eight new patents include:
Japanese patent No. 6648170
Korean patent No. 10-2143220
The new patents join Nuburu’s foundational patent, ‘3D printing Devices and Methods’ PCT/US14/35928, which was awarded in 16 countries with several other applications and continuations pending around the world, including with the US patent office.
‘Nuburu’s IP portfolio is broad and deep,’ said CEO Dr Guy Gilliland. ‘Industry analysts and organisations have recognised the strength of our technology…’
‘These patents firmly establish that Nuburu invented the blue laser technology for 3D printing and material processing,’ remarked Dr Mark Zediker, founder and chairman of Nuburu. ‘The company portfolio widely covers blue laser technology, multimode and single mode as well as broad applications within 3D printing and material processing.’
Twenty-two patents have been awarded to the firm to date, Zediker added, with 90 applications currently in process for a number of claims in excess of 4,000.

Nuburu has also been awarded US Patent No. 10,940,562, which covers all forms of 3D printing, welding, and methods of opening up the keyhole using blue laser light.
'It is a core addition to the broad list of 34 patents Nuburu has already been awarded,' said Zediker. '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.'
