| Abstract | The Laser Powder Bed Fusion (LPBF) process is an additive manufacturing technique which achieves consolidation of metal powder using a laser to selectively melt, layer-by-layer, parts of a powder bed. At the melt pool (MP) scale, driving forces include laser heating, solid-liquid phase change, evaporation, and surface tension. Evidence shows that reliable numerical predictions of MP evolution require thermo-fluid solvers modeling all the aforementioned terms [1]. These terms induce strong coupling between the governing equations, requiring additional considerations to ensure accurate resolution. However, few LPBF publications report a complete description of their frameworks: assumptions are not stated and the solution sensitivity to the space and time discretization is rarely assessed. This makes it difficult to reproduce the results and assess their adequacy |
