The Formation of Humps and Ripples During Selective Laser Melting of 316l Stainless Steel

Humps and ripples are typical surface morphologies obtained in the selective laser melting processes and have an important influence on the surface quality of the fabricated parts. In this study, a three-dimensional powder-scale model is presented to investigate the molten behavior and the resulting...
