Abstract: Mask-image projection stereolithography (MIP-SLA) was studied to solve the manufacturing problem of ceramic cores of aero-engine hollow turbine blades using 3D printing. We built an MIP-SLA platform to study the preparation method of ceramic slurry and the parameter configuration during printing process. Effects of photosensitive resin type, solid content, size of ceramic particles, content of dispersant, and milling time on the properties of ceramic slurry were all analyzed using the ceramic paste which was prepared by mixing the photosensitive resin and the ceramic particles with the ball mill. The printing results under different configuration parameters were also compared and analyzed.

Key words: MIP-SLA, turbine blade, ceramic core, three-dimensional(3D) printing
