Processing and 3D printing of SiCN polymer‐derived ceramics

Abstract Preceramic polymer resins are attractive for the 3D printing of net‐shaped ceramic components. Recently various processes have been demonstrated for 3D printing of polymer‐derived ceramics (PDCs). Ultimately in these processes, the process outcomes strongly depend on the process parameters. In particular, for PDCs the ceramic density, and ceramic yield are affected by the catalyst concentration and cross‐linking duration. Here, we use thermal analysis and FTIR to quantify the interrelation of the process parameters on the process outcome for polysilazanes and demonstrate 3D printing of PDC components based on the best‐identified process parameters. The results of this work can be used as guidelines for future additive manufacturing of PDCs.
