Precursor ceramics have the advantages of designable molecular structure, controllable chemical composition, convenient processing and forming,excellent mechanical properties, easy to form complex components, and easy to realize the integration of structure and function. Compared with ceramic materials prepared by traditional powder sintering method, precursor ceramics are easy to design and form, which is of great significance to solve the material bottleneck problem faced by aviation, aerospace and national defense advanced weapons and equipments. Driven by the additive manufacturing technology of ceramic, the development of precursor ceramics has ushered in a new opportunity. More and more attention has been paid to the research of additive manufacturing precursor ceramics. The research and application progress of additive manufacturing precursor ceramics are introduced, the advantages and disadvantages of various ceramic additive manufacturing technologies are summarized, and the existing problems and development trend are discussed and prospected.
