 This review examines the current state of the art for selective laser melting, SLM, which allows for the production of free-form metal parts with high mechanical properties. The effects of various process parameters on the properties of the final part are discussed, including the starting powder properties, laser power and speed, layer thickness, and scanning strategy. Additionally, the micro structures of the LC10MG material are described, along with their corresponding tensile and fatigue properties. This article was authored by Francesco Treveson, Flaviana Calignano, Massimolo Russo, and others.
