6K, a North Andover, MA-based leader in sustainable production of engineered materials for lithium-ion batteries and additive manufacturing produced from its UniMelt plasma technology, raised $102M in Series D funding.
Koch Strategic Platforms led the round with participation by Energy Impact Partners, Albemarle and HG Ventures.
The company intends to use the funds for production expansion for premium 3D metal powders in its Additive division and for the deployment of cathode production plants in its Energy division.
Led by CEO Aaron Bent, 6K has developed UniMelt, a proprietary advanced microwave plasma production system, to transform engineered materials into products that advance industries across additive manufacturing, renewable energy, aerospace, consumer electronics, and more. 6K’s UniMelt® system replaces a three-day, multi-step, high waste chemical co-precipitation (hydro-met) process with one that is ultra-clean and ultra-fast (as low as 2 seconds), powered by a 6000K microwave plasma.
The UniMelt systems are already deployed in 24/7 high volume production in 6K Additive’s 45 acre, ISO9001 certified facility.
The $102 million raised is the first of two funding tranches for Series D, which is expected to reach $150 million in total. With an expected close in spring 2022, the company will add a limited group of strategic investors.
