摘要

With unique manufacturing technology, the additive manufacturing technology divides the three-dimensional object into count-less two-dimensional laminates. Compared with the traditional material reduction manufacturing method, it has the characteristics of saving materials, being fast, and especially suitable for single and small batch parts and the rapid manufacturing of parts with complex shapes and internal structures. In this paper, various methods of additive manufacturing technology are reviewed. This paper introduces the characterist-ics of selective laser melting technology and its forming equipment system. On this basis, the technical defects of selective laser melting technology are analyzed, and the status of controlling defects in SLM technology is explained. In the end, the prospects of additive manufac-turing technology are described.
