A preparation method of ceramic direct ink writing based on solvent evaporation was proposed, and the process parameters to change the solvent evaporation rate of ceramic slurry in the printing process were adjusted. For zirconia ceramic, a zirconia ceramic slurry with a high solid loading was prepared, and the rheological properties and printability of zirconia ceramic slurries with different solid loadings were analyzed. The results show that zirconia ceramic slurries with 54%-58% (volume fraction) solid loadings can be used to form a ceramic body without deformation or collapse by changing the solvent evaporation rate. Based on the preparation and characterization of ceramic tooth and cuboid samples, it is verified that this method can prepare some complex-shaped ceramic parts with a high strength.
