This paper conducts an in-depth investigation into the field of Selective Laser Melting (SLM) within additive manufacturing (AM) technology, providing a detailed analysis of its market background, current status, and development prospects. As a revolutionary pioneer in future manufacturing, AM technology has rapidly emerged in recent years and found widespread application in high-end manufacturing sectors such as scientific research, healthcare, military industry, aerospace, and aviation. SLM technology, as a critical branch of AM, has become a focal point in numerous fields due to its advantages of high precision, high efficiency, and material diversity. This paper first outlines the industry background of AM technology, including its development history, primary methods, and technical characteristics. Subsequently, by comparatively analyzing the key technical parameters of major domestic and international SLM printing equipment brands, the current market status of SLM technology is revealed. In the competitor analysis, the paper focuses on the latest advancements in melt pool temperature monitoring technology and powder spreading detection technology. It points out the limitations of traditional temperature measurement techniques in aspects such as single-point measurement, accuracy, and response speed. The innovative approaches adopted in this project—namely, photoelectric sensor-fused thermal imaging processing technology and artificial intelligence (AI)-based machine vision inspection methods—are introduced. Furthermore, the paper explores future development trends for SLM technology, including product line expansion, service upgrades, and the positive impact of policy support and industry development. Through the research conducted in this project, we deeply appreciate the critical importance of technological innovation for enhancing the forming success rate of SLM technology and reducing material and energy costs.
