Abstract: Under the background of information warfare characterized by intelligence, equipment maintenance and support capability has emerged as a crucial factor influencing the combat effectiveness of military forces and is the key to sustaining fighting capacity. Focusing on the requirements of future intelligent warfare and driven by the demands of equipment maintenance and support proposes, the composition and architecture of an intelligent equipment maintenance and support system were proposed based on additive manufacturing technology, and the specific processes involved in intelligent equipment maintenance and support utilizing this technology were defined. It aims to provide technical support for intelligent equipment maintenance and support, so as to improve the quality efficiency and comprehensive capability of support.
