Abstract: The current situation of maintenance and support for armored equipment was sorted out, the mainstream additive manufacturing technologies and their transformative impact on the existing support mode were analyzed, and in view of the characteristics of materials, structures and performances of vulnerable parts of armored equipment and the requirements of the usage environment of armored equipment, suggestions and requirements for the development of rapid additive manufacturing and repair technologies based on the field environment were put forward. It provides technical support for enhancing the forward autonomous support capability of armored equipment.
