Additive Manufacturing
Included in the AMOS consortium are research organizations, aerospace OEMs, repair providers and universities. Their projects, according to a representative, will aim to “provide a fundamental under- standing of thermal and mechanical behav- ior of powder and wire material during deposition. They also will provide a sim- ulation and optimization platform for
industrial partners to further develop their component-specific applications.”
AMOS also will investigate how additive repair techniques can be factored into the design of new components to optimize efficiency over their life cycle, and the qualification of innovative repair processes that do not comply with current industry specifications.
optics, process enclosure, filter unit and control cabinet, are integrated into the compact housing of the TruPrint 1000.
During the build, a layer of metal powder is applied to a substrate plate and then a 200-W laser fuses the cross- section of the geometry to the plate. After the exposure, the plate is lowered and the next layer of powder is applied. The procedure is repeated until the part is finished. The entire process takes place inside the enclosure, blanketed by pro- tective gas, and at an oxygen content of 0.1 percent for maximum part quality. Trumpf: www.us.trumpf.com
Canadian-European Consortium to Study 3D Metal Printing for Aerospace-Repair Projects
Nine partners from Canada, France, Sweden and the UK have formed a research consortium to study additive- manufacturing technology for repair of aerospace-industry components. Dubbed AMOS (Additive Manufacturing Optimization and Simulation), consortium projects will focus on direct-energy deposition tech- niques that combine laser or arc-welding tools with automated or robotic control to accurately deposit and melt metal pow- der or wire.
