During Laser Powder-Bed Fusion (LPBF)Laser Powder-Bed Fusion (LPBF), the surface formation of the selected-melted powder-bed region is subject to a melting-solidification process along the line-scans and sensitive to the process conditions. This study focuses on the surface formation of mesoscopic l...
