Basic Mechanism of Surface Topography Evolution in Electron Beam Based Additive Manufacturing

Basic Mechanism of Surface Topography Evolution in Electron Beam Based Additive Manufacturing

This study introduces and verifies a basic mechanism of surface topography evolution in electron beam additive manufacturing (E-PBF). A semi-analytical heat conduction model is used to examine the spatio-temporal evolution of the meltpool and segment the build surface according to the emerging persi...
