Simulation of surface deformation control during selective laser melting of AlSi10Mg powder using an external magnetic field

AIP Advances, 2019
Selective laser melting (SLM) produces complex physical behaviors. After laser melting, the molten pool condenses with an uneven surface, which influences the next powder spreading process and affects the quality of the final product.
