摘　　要：陶瓷型芯在航空发动机空心涡轮叶片的熔模铸造中起到关键作用。3D打印技术作为新一代的成型技术,具有无需模具、制造周期短、精度高等优点,正在逐渐替代传统的陶瓷型芯制备工艺。本文总结了光固化技术、选择性激光烧结、直写成型技术和分层挤出成型等目前在陶瓷型芯领域使用较多的3D打印技术,针对3D打印陶瓷型芯打印精度低、力学性能与气孔率适配性差、结构性能各向异性等局限性探讨了性能优化研究现状,并对该领域的发展进行了展望。Ceramic cores have an impact on the precious casting of the engine hollow blades.3D printing technology,as a novel generation of molding technology,is replacing the conventional ceramic core manufacture process due to the advantages of no mold,short manufacturing cycle,and high accuracy.This review summarized the existing 3D printing technologies for ceramic cores such as light-curing technology,selective laser sintering,direct-write forming technology and layered extrusion,and discussed the current research work on the performance optimization for ceramic cores prepared by 3D printing based on their shortcomings(i.e.,low printing accuracy,poor compatibility between mechanical property and porosity,and anisotropy in structure and property).In addition,the future development of this technology was also prospected.
