Abstract: The additive manufacturing technology has the advantage of rapid manufacturing of single-piece and small-batch complex structures used in aerospace applications, and integration of design, materials and manufacturing will be the direction for its future development. This paper analyzes three aspects of application and development of additive manufacturing in the field of aerospace, focusing on the manufacturing of aero-engine turbine blades, high-performance Poly-Ether-Ether-Ketone (PEEK) and its composites, continuous fiber reinforced resin composites, and space 3D printing. The research status of additive manufacturing technology at home and abroad and in Xi'an Jiaotong University is also introduced. The application of additive manufacturing technology for turbine blades can effectively improve the manufacturing efficiency and reduce costs. In the future, this technology can meet the manufacturing of high-performance superalloy and ceramic matrix composite blades. The additive manufacturing of high-performance lightweight polymer PEEK and its composites are applied in forming of structure parts with high mechanical properties and radio absorbing functional parts, which will change the existing design and materials and promote the integrated development of structure and function. The additive manufacturing of continuous fiber reinforced resin composites will drive the new development of forming of moldless fiber composites, and 3D printing in space will change the aerospace manufacturing model in the future. The additive manufacturing technology will revolutionize the aerospace manufacturing technology.
