AM Prototype Cuts Weight, Lead Time by Half on Large Rocket PartApril 3, 2019
|At AMUG 2019,GE Additive displayed this prototype of a ULA Vulcan Centaur rocket part, a bellows housing. The AM prototype reduced weight by 60 percent and lead time by half.|
Project A.T.L.A.S. represents GE Additive’s program to develop the next generation of large additive manufacturing (AM) machines. The company developed this beta machine, which reportedly offers the world’s largest direct metal laser melting (DMLM) build envelope, in only 9 mo. The ‘meter-class’ laser powder bed fusion machine showcases several key technologies, including scalable architecture, combined with feature resolution and build-rate speeds surpassing today’s machines, according to GE Additive officials.
Select customers, report company officials, currently operate beta machines to gain early appreciation of their current capabilities and long-term potential, and to provide learning and experience feedback to enhance future machine configurations.
The beta build envelope measures 950 by 810 by 300 mm (scalable). Machine attributes as reported by GE Additive include gantry-based architecture, use of as many as four 1.5-kW lasers, state-of-the-art scanner with 3D focusing, discrete material dosing, optimal air-flow control over the print area, high feature resolution, and process and machine health monitoring courtesy of GE’s Predix software.
