Abstract Scope |
The reuse of metal powder in additive manufacturing provides economic and environmental advantages through reduced raw material consumption and minimized waste. However, repeated powder reuse introduces variability in material properties, impacting melt pool stability and potentially compromising the structural integrity of manufactured parts.
A 2D numerical model is developed to address these challenges by simulating the Electron Beam Melting (EBM) process with powder bed composed of a mixture of virgin and reused alloy powders. Overall, an ICME-based approach is implemented to optimize the blend ratios of virgin and reused powders, aiming to reduce defect formation and improve cost efficiency.
This framework provides insights into powder management strategies to limit defect formation by optimizing the mixing ratio of virgin and reused powders for consistent part performance in additively manufactured EBM components. |
