NUBURU bolsters 3D printing IP
NUBURU Inc of Centennial, CO, USA (which was founded in 2015) has been awarded US patent no. 10,971,896 by the US Patent Office. The new patent covers spatial, polarization and wavelength combination of blue laser diodes to make a high-power, high-brightness blue laser diode system, which enables significant gains in speed and quality for metal processing.
In 2021 so far, the firm has added nine patents across 3D printing and material processing. NUBURU’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).
“Our new patent encompasses all methods of combining blue laser diodes for developing high-power, high-brightness blue lasers,” says founder & chairman Dr Mark Zediker. “Winning this landmark patent is another strong testament to our technological leadership across 3D printing and material processing and the innovations we are bringing to the industry.”
NUBURU says that its blue laser is suitable for materials processing applications across e-mobility and automotive, energy storage, aerospace and additive manufacturing. In many industrial applications, critical materials such as copper, stainless steel and aluminium do not absorb much of the infrared wavelengths transmitted by traditional industrial lasers, which leads to lower quality joints. NUBURU 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. NUBURU’s blue lasers can also address complex situations such as the joining of dissimilar metals.
