摘要
Ceramic materials are widely used because of their excellent mechanical properties and chemical stability. However,due to their high hardness and brittleness,there are challenges in the forming and processing of ceramic components. Traditional ceramic molding technologies have been unable to meet requirements of the production of complex precise ceramics. Recently,ceramic additive manufacturing technology has developed rapidly. Stereolithography 3D printing technology stands out with its unique advantages such as fast printing speed,high molding accuracy and smooth surface of green bodies. As the raw material of stereolithography,the properties of ceramic slurry affect the printing process and molding quality of ceramic products seriously. High quality stereolithography ceramic slurry has the characteristics of high solid content,low viscosity,and anti-settling. Due to the variety of components,many factors affect the properties of ceramic slurry. How to obtain the best formulation of ceramic slurry has always been a difficult problem. For this problem,based on a brief introduction to the theory of stereolithography 3D printing technology and the preparation principle of ceramic slurry,starting from the properties of ceramic powder,this paper focuses on the research progress of the effects of ceramic powder properties,particle size distribution and grading design on the rheology,stability and photopolymerization performance of the slurry. Finally,we summarize and prospect optimization methods of ceramic raw materials in the preparation of ceramic slurry based by stereolithography 3D printing. This paper is aiming to provide a reference for researchers to improve slurry properties by selecting and designing raw ceramic materials.
