AM Conference Speaker: Optomec

The choice between open-atmosphere and inert processing involves a careful comparison of the metallurgical results of various metal alloys built in both environments. Learn more during the Additive Manufacturing Conference.

Laser Engineered Net Shaping (LENS) is a laser metal deposition-based additive manufacturing process that is used for complete component builds and repairs. Laser metal deposition is best done in an oxygen-free environment; however, it is not always practical or cost effective to do so. According to Optomec Inc., there are instances when an open-atmosphere environment is acceptable. Optomec compares metallurgical results such as porosity, inclusions, surface finish and overall quality of the build between metal alloys built in both inert and open-atmosphere processing to determine when an inert atmosphere is required and when an open-atmosphere environment is acceptable.

Jim Cann, LENS sales manager for Optomec, will present an overview of the types of systems used for inert and open-atmosphere processing, including hybrid CNC and additive-only open-atmosphere systems. He will also discuss the methods that Optomec uses to create very low (less than 10 ppm oxygen) levels for LENS technology and the trade-offs to utilize LENS in a production environment. Cann’s presentation takes place during the upcoming Additive Manufacturing Conference, co-located with IMTS 2016, at 9:45 a.m. on Tuesday, September 13, in room W375-B.
