Abstract Scope |
Reusing powders in metal-based additive manufacturing (AM) can help to reduce the production cost and increase the sustainability of the process. Gas atomized AlSi10Mg is frequently used in the AM industry due to the increasing need for parts with complex geometry and high strength. However, it has been not thoroughly investigated whether reusing the powder significantly influences the mechanical behavior of the deposited parts. In this project, blocks were deposited using LENS® with excess powder being collected and reused for five cycles. In order to investigate the effects of reusing powders on microstructure, morphology, and flowability of powder particles, extensive characterization has been done on virgin and reused powder. The blocks have also been characterized to understand the effect of reusing powder on microstructure, density, and mechanical properties. The results from this experiment provide insight into the limits of reusing AlSi10Mg powder in LENS® to build components with competitive properties. |
