摘　　要：介绍了聚合物、陶瓷、金属和多材料增材制造技术在单晶涡轮叶片成形中的应用。增材制造与熔模铸造相结合提高了熔模铸造单晶叶片的柔性,加速了叶片研制与生产过程;特别是多材料增材制造技术的发展有望为实现陶瓷型芯、铸型的控形与控性相结合提供新途径,而重熔-定向凝固技术的发展,有望为单晶叶片成形提供新思路。但在陶瓷材料研究、工艺控制等方面,仍面临诸多挑战。The application of polymer,ceramic,metal and multi-material additive manufacturing techniques to molding of single crystal turbine blades is introduced.The combination of additive manufacturing and investment casting improves the flexibility of investment casting single crystal blades,and accelerates the development and production process of blades.Especially,the development of multi-material additive manufacturing technology is expected to provide a new way to realize the combination of controlling shape and property for ceramic core and shell mold,and the development of remelting-directional solidification technology is expected to provide a new idea for the molding of single crystal blades.But there are still many challenges in ceramic materials research and process control.
