3D printing technology is an emerging technology that is rapidly developing in the manufacturing field. It can easily and automatically manufacture complex three-dimensional shapes that are difficult to be produced by various processing methods. Printable ceramic materials are prepared by mixing photosensitive resin and different ceramic powders. By studying the effects of dispersant, slurry, PH value, silica particle size and solid phase content on slurry viscosity and fluidity, low viscosity Ceramic slurry with high solid phase content and good fluidity. The effects of different solid phase contents on the bending strength, firing shrinkage, porosity and density of ceramics were tested. The results show that the bending strength of sintered SiO2 ceramics reaches 15.78Mpa at a solid content of 70vol %. The density was 76.21%, porosity was 40.04%, sintering shrinkage was 0.89%.
