Abstract: Stereo light-cured apparatus technology is an emerging additive manufacturing process for producing high-precision and high-performance ceramic parts. The preparation of ceramic slurry with good flowability and high solid phases content is the advantage to stereo lithography apparatus additive manufacturing. The influences of solid phase content, monomers, dispersants, powder gradation and other factors on the rheological properties of the slurry were disscussed, and the current material selection principles for the preparation oflight-cured Al2O3 ceramic slurry with high solid phase content and low viscosity were summarized. The guiding methods for preparinglight-cured Al2O3 ceramic slurry with high solid phase content and low viscosity were summarized, and the main trends and challenges in the development of high performance photocurable Al2O3 ceramic slurry were pointed out.
Key words: stero light-cured apparatus technology, Al2O3 ceramic slurry, solid phase content, viscosity, monomer, dispersant, powder particle size
