Research Progress of Stereolithography 3D Printing of Silicon Nitride Ceramics
Compared to other additive manufacturing techniques,stereolithography 3D printing exhibits unique advantages in fabricating ceramics with complex structures,high density,and superior surface accuracy,thus emerging as a focal point in ceramic additive manufacturing research.However,the high refractive index and strong light absorption properties of silicon nitride ceramics pose challenges in photopolymerization processes,hampering their development and application.This paper analyzes the rheological behavior and curing characteristics of silicon nitride ceramic slurries,and summarizes the challenges encountered in their rheological and curing properties.Furthermore,it consolidates research efforts aimed at enhancing the photopolymerization performance of silicon nitride ceramic slurries and discusses several approaches such as powder modification and resin composition regulation.Finally,detailed insights are provided into the future trends and directions of silicon nitride ceramics stereolithography 3D printing.
