6K Additive says that it will increase production of metal powders for additive manufacturing (AM).

The company plans to add 20,000 ft2 of powder production capacity install four new UniMelt microwave plasma 3D printers and incorporate a new 15,000 ft2 material feedstock preparation building in Pennsylvania, USA. It also aims to hire 35 new employees.

This follows “rapid growth” in demand for nickel, titanium and refractory powders over the last year, according to 6K.

The Pennsylvania site currently produces nickel 718 & 625, titanium-64, stainless steel, copper and aluminium alloys, while 6K’s headquarters in North Andover, Massachusetts produces tungsten, rhenium and niobium-based alloys for hypersonic, defense, and rocket applications.

“Global unrest has shed a major spotlight on our nations supply chain vulnerability for critical materials,” said 6K Additive’s president Frank Roberts. “This expansion will help us meet customer demands in the coming years and ensure efficiencies in current and future operations.”
