【Abstract】 This study systematically investigates the dispersion and curing behavior of Si3N4 ceramic powders in a photocurable resin system, focusing on the effects of resin formulation, dispersant type, and dosage on the rheological and photocuring properties of ceramic slurries. The results show that a rational combination of resins with different functionalities can significantly enhance both slurry flowability and curing depth. Moreover, selecting appropriate dispersants and optimizing their addition effectively improves the dispersion stability of Si3N4 powders in the resin matrix, thereby reducing slurry viscosity. This work provides theoretical support and process guidance for the development of high-solid-loading, high-curing-depth Si3N4 ceramic slurries for photocuring-based additive manufacturing.更多还原
