6K Additive adds more additive manufacturing experts to team

Stay up to date with everything that is happening in the wonderful world of AM via our LinkedIn community.

6K and 6K Additive hired additional highly experienced additive manufacturing experts, who will all serve to build out 6K’s growing sustainably sourced AM powders. The new team members bring extensive knowledge in quality, powder manufacturing and process as the organization begins production of its Onyx line of AM premium powders in its recently commissioned 40,000 square foot “lights out” facility.

6K’s UniMelt system is the world’s only microwave production-scale plasma. With a highly uniform and precise plasma zone with zero contamination, it is capable of high throughput production of advanced materials including Onyx In718 and Onyx Ti64 AM powders. 6K’s UniMelt technology can also spheroidize ferrous alloys like SS17-4PH, SS316, other nickel superalloys including Inconel 625, HX, cobalt-base alloys like CoCr, refractory metals like Mo, W, Re, reactive alloys such as Ti-6-4, TiAl, Al alloys, as well as high-temperature ceramics such as MY and YSZ. 6K Additive recently commissioned its first two UniMelt microwave plasma production systems for Nickel alloy and Ti64 manufacturing. The company also recently announced a million dollar DLA award to convert US defense scrap to premium AM powder.

The near $1M DLA award will support 6K’s capability to reclaim nickel superalloy scrap components for conversion into aerospace grade AM powders

The new additive manufacturing experts prepare the company for further growth and product development.

Dr. George Meng joins 6K from GE Aviation as the Director of Process for Additive. His experience at GE saw him develop and industrialize a new powder for Plasma Suspension Spray coating, and a new no-line-of-sight thermal spray process for a large critical Ti-based system. Dr. Meng also worked for GE Power and led the successful development and industrialization of abradable coatings across different gas turbine engines. Dr. Meng won the highest manufacturing engineering award globally at GE Power. Prior to GE, Meng worked at Praxair Surface Technologies, where he was responsible for developing new gas atomized powders. His work included developing new quasi-crystalline powders in collaboration with a Nobel Chemistry Prize recipient.

John Meyer joins 6K from Carpenter Technology Corporation to serve as Director of Technology, AM Products. He served Carpenter Technology as its Principal Metallurgist responsible for powder technology and process improvement. Meyer also managed the powder metallurgy group for its five powder production facilities worldwide including oversight of new product implementation, process technology integration, and support of powder metallurgy. Since 2016, Meyer has served as the Materials Subcommittee Chairman for the SAE Aerospace Material Systems – Additive Manufacturing standards and is also a member of the ASM International and American Powder Metallurgy Institute.

Dave Novotnak brings over thirty years of experience as an expert in materials and metallurgical engineering to 6K, where he now serves as Production Process Manager, AM Products. Prior to joining 6K, Novotnak held the position of Senior Materials Engineer at Carpenter Powders Products having spent close to twenty years in progressing powder manufacturing processes. Novotnak also brings direct materials application experience in aerospace having spent fourteen years at Pratt & Whitney as Senior Metallurgical Engineer.

Joe Muha is a thirty-plus-year veteran in AM powders and joins 6K as its Quality Manager. He was Principle Powder Metallurgist for Carpenter Powders Products and a quality engineer. Prior to his employment at Carpenter, Muha worked as a quality engineer and chemical lab supervisor at ATI Powder Metals. Muha also spent fifteen years at Crucible Research where he was responsible for research and quality assurance.

Frank Roberts, President of 6K Additive, said that: “Adding these experienced leaders to the team underpins our strategy of advancing premium powders in the additive manufacturing space. Each new member brings deep domain expertise as well as an incredible passion for success, quality and leadership to the team. Their combined 100+ year’s expertise in AM powder, materials engineering and metallurgy will allow us to rapidly achieve the quality and production demands brought about by leading organizations in the medical, aerospace and defense markets who drive the application requirements for advanced materials.”
