摘要：

Selective laser melting (SLM) technology has been widely used in biomedical, aerospace, automotive and military manufacturing because of its short processing cycle and easy forming of complex components. However, due to the complex interaction between laser and powder in the forming process, the defects of laser selective melting parts show diversified characteristics, and SLM is more difficult to control, which limits the development and application of this technology to a certain extent. The research on the formation mechanism and control methods of spatter defects is one of the research hotspots in recent years. This paper summarizes the relevant recent research achievements. Taking powder, molten pool and forming layer as clues, this review expounds the spatter formation mechanism and control methods in the SLM process from four parts: the influence of spatter on formed parts, the cause of spatter formation, the monitoring and control methods and the future research directions, and the future development direction is proposed.
