NUBURU is patented for blue laser welding and several kilowatts blue laser

NUBURU, an American manufacturer of high-power and high-brightness industrial blue lasers, announced on April 21 that it has been granted new patents that expand its intellectual property portfolio to cover a wide range of blue lasers for welding and other applications.

In recent years, a growing number of customers in the market want to phase out slow, high-cost process methods such as ultrasonic and resistance welding. NUBURU's Blue laser addresses two key manufacturing challenges for metal connections in megatrends such as electric vehicles and consumer electronics: low volume and slow processing.

While production of blue lasers could be pushed back decades at the earliest, the transition to mass production is driving customer demand for faster, contact-free processes that are not affected by low utilisation and high maintenance costs. Infrared lasers eliminate contact and speed limitations; However, due to the infrared color of the light, they are very inefficient, resulting in partial damage and ultimately cannot be used in some battery welds.

The NUBURU Blue Laser addresses the need for a contact-free, high-speed, low to defect-free process for manufacturing batteries and electric vehicles. For now, even big trends in the electric car market can't offset the low yields on traditional technologies. Volume corresponds directly to short - and late-stage production costs, warranty risk, and customer safety (battery fire), and NUBURU addresses exactly this set of pain points for customers.

NUBURU's Blue laser portfolio has also made significant market progress in other major market segments such as consumer electronics. Driven by 5G, handset makers have turned to NUBURU for solutions to overcome problems with existing manufacturing techniques, such as press assembly, welding and other mechanical techniques. They need to address inefficient, time-consuming processes that create production and productivity constraints.

NUBURU's AO laser has now been used for more than a year in the production of mobile phone soaking panels after a 12-18 month application and technical qualification process. The process involves welding thin copper less than 200 microns, a fraction of the size of a mobile phone, continuously and very quickly. In contrast, customers are more disappointed with infrared lasers. Although traditional infrared fiber lasers offer a contact-free approach, they simply cut the material rather than welding it due to low absorption at infrared wavelengths.

Blue Laser provides the ideal solution for customers, it is a contactless, repeatable, high-speed solution that is 10-100 times faster than the original method. The NUBURU BL, introduced in January, is combined with scanners to further enhance customer value with faster speeds, more precise weld geometry and lower cost of ownership.

About Nuburu

Founded in 2015 and headquartered in Colorado, NUBURU is a developer and manufacturer of industrial blue lasers that use basic physics and their high-brightness, high-power design to produce lasers in materials processing that are processed faster and of higher quality than currently available alternatives, Including laser welding and additive manufacturing of copper, gold, aluminum and other industrially important metals. NUBURU's industrial blue laser forms a precise and even fault-free weld that is about eight times faster than conventional methods.
