摘　　要：为解决航空发动机空心涡轮叶片陶瓷型芯的3D打印难题,研究基于图像投影的复杂结构陶瓷型芯光固化成型(mask-image projection stereolithography,MIP-SLA)方法。搭建MIP-SLA工艺系统平台,对陶瓷浆料的制备和打印工艺参数的配置进行研究。分析利用球磨机将光敏树脂和陶瓷颗粒进行混合制备陶瓷浆料时,光敏树脂类型、固相含量、陶瓷颗粒粒径、分散剂含量和球磨时间对陶瓷浆料性能的影响。对不同配置参数下的打印效果进行对比分析,对确定的最佳打印工艺参数进行打印效果验证。Mask-image projection stereolithography(MIP-SLA)was studied to solve the manufacturing problem of ceramic cores of aero-engine hollow turbine blades using 3 D 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.
