Satellite antenna produced with 3-D printing
Altair, Troy, Mich., has announced that RUAG Space, with the support of Altair ProductDesign, has built a redesigned, optimized antenna support for an Earth observation satellite, to be produced using industrial additive manufacturing, or 3-D printing.
Engineers used Altair HyperWorks® OptiStruct® to ensure load-sufficient material distribution in the antenna. For the design, engineers used solidThinking Evolve®. The component was then manufactured with a 3-D printer. Using topology optimization in conjunction with additive manufacturing, the team achieved light weight and stiffness performance characteristics not possible using conventional analysis and manufacturing techniques. EOS handled the manufacturing of the aluminum components with additive manufacturing.
The 15.7-in.-long antenna support is one of the longest metal components ever produced using the powder bed manufacturing method, the company reports.
