Abstract: SiC ceramics have excellent mechanical properties and good thermal properties, and are one of the ideal materials for preparing space optical mirrors. SiC ceramic mirrors prepared by traditional forming technology generally have problems such as low light weight and long preparation cycle, which are difficult to meet the development needs of space optical systems. At present, additive manufacturing technology shows its great potential in the preparation of ultra-lightweight mirrors with low cost and short cycle. In this paper, the material properties of common mirrors are compared firstly. Then, the research progress of additive manufacturing technology for SiC ceramic mirrors is reviewed. The component design, preparation process and densification method of SiC ceramic mirrors preparation process are discussed in detail, and the technical route of SiC ceramic mirrors prepared by additive manufacturing technology is summarized. Finally, the future development of additive manufacturing technology for SiC ceramic mirrors is prospected.
