In additive manufacturing rapid development and increasing green under the joint action of sustainable development, additive repair technology is developing rapidly in various fields of Chinese industry. At the same time, our country issued relevant policies to strongly support the development of additive manufacturing technology, and additive repair technology has become mature and developed rapidly with a large number of scholars, which has a wide application prospect. This paper introduces the material to repair the main application of key technologies, as well as the increase of material repair technology in the field of aerospace navigation, military areas, as well as the present situation of the application of engineering machinery area, etc. Moreover, the current problems faced by additive repair application technology are put forward, and finally the future development direction of additive repair technology is prospected and suggested.
