[HTML][HTML] High-fidelity Modeling of Multilayer Building Process in Electron Beam Powder Bed Fusion: Build-quality Prediction and Formation-Mechanism Investigation
High-fidelity simulations of powder bed fusion (PBF) additive manufacturing have made
significant progress over the past decade. In this study, an efficient two-dimensional frame
was developed for simulating the electron beam PBF process with hundreds of tracks for the
direct prediction of the build quality. The applicable parameter range of the developed
model was determined by comparing the heat transfer with that in three-dimensional cases.
Subsequently, powder deposition and selective melting were coupled for a continuous …
