Abstract The development of metal additive manufacturing technology provides a new way on the research of digitization, personalized customization, high-performance and short period for the maintenance and support of military aircraft, which can improve the technical level and ability of military aircraft maintenance and support. In this paper, the current situation of military aircraft maintenance and support at home and abroad is summarized and the application advantages of metal additive manufacturing technology are pointed out. The typical damage forms of military aircraft parts, the applicability of different additive manufacturing processes and the selection scheme of repair process are introduced and the key technologies such as reverse modeling, structural optimization and intelligent robot are analyzed. The main problems as well as the solutions of low technology maturity and reliability, unclear repair principle and inconsistent standards and specifications are described in detail. The paper also points out the future development direction and trend of additive manufacturing technology in the field of military aircraft maintenance and support and gives specific application suggestions.
