Abstract: Laser additive manufacturing technique has the advantage of rapidly forming complex-shaped parts, and has received widespread attention in recent years. Two laser additive manufacturing techniques, directed energy deposition and selective laser melting, are introduced. The research progress of laser additive manufacturing formed 316L stainless steel is reviewed from the aspects of common defect, microstructure and texture, and mechanical properties. The current problems of laser additive manufacturing formed 316L stainless steel are analyzed, and its development prospects are prospected.
