| Abstract Scope |
In the laser powder fusion process, the powder spattering contributes to the formation of defects such as lack-of-fusion and surface irregularity. The powder-gas interaction that triggers such spattering can be inferred from experimental observations but has not been well quantified. In this work, we use a computational physics model to investigate the powder motion. The effects of various processing conditions on the laser-induced gas flow, powder-gas interaction forces, and the resultant powder motion will be investigated systematically. |
