Abstract: As one of the main means of additive manufacturing technology, laser selective sintering/melting technology has obvious advantages in fabricating complex structural parts, shortening manufacturing cycle and reducing production cost. Ceramic materials have great prospects in automobile, medical treatment, aerospace, battery and other fields. Forming oxide ceramics by using stimulated light sintering technology can greatly expand the application field. Currently, the fabrication technology for special materials is not mature and the traditional SLM equipment cannot meet the requirements. In this article, the process principles and research progress of oxide ceramic laser selective sintering melting technology will be summarized, in terms of material properties, powder laying mode, heating temperature and forming quality. The main reasons for restricting the forming effect will be discussed. Finally, the application of laser sintering technology in oxide ceramic manufacturing is prospected.

Key words: oxide ceramics; selective laser sintering and melting; forming process
