Abstract
Surface topography of focused down-beam single-pass modeling plays a paramount function in electron beam surface modeling. However, there remains a challenge to understand the formation mechanisms of different surface morphologies and correlation with e-beam process parameters. This paper describes the printing process in vacuum using a high-fidelity model of focused down-beam single-pass modeling. Results indicated that the high simulation result and the wide simulation result were 219.5 μm and 2947.8 μm, respectively, accompanied by an error rate of 6.7% for the experimental data. This could enhance the understanding of surface morphologies mechanisms and contribute to the improvement of metal topography manufacturing processes.
