摘　　要：Si_(3)N_(4)/SiCN ceramics have been extensively explored for applications in the aerospace,mechanical engineering,and biomedical fields.Recently,there has been significant focus on the additive manufacturing(AM)of polymer-derived ceramic(PDC)technology for fabricating Si_(3)N_(4)/SiCN ceramics.The chemical structure and composition of the preceramic polymer precursors have a crucial influence on the performance of ceramic products.In this paper,recent advances in the use of polysilazane and polycarbosilazane precursors in AM are reviewed and an outlook for future development is presented.The findings of this study could spark inspiration and reflection regarding AM applications and synthetic technology.It is believed that the development of PDCs in ceramic fabrication will become more versatile and application-oriented and provide more freedom in the design of high-performance ceramics.
