Abstract Due to the characteristics of layered manufacturing, additive manufacturing (AM) is an effective means to realize the forming of complex, integrated and personalized high-performance components, which changes the design from process-oriented to performance-oriented design, greatly improves the design space, and has a large application space in aerospace and other fields. To meet the multi-performance requirements of high-end equipment for components,the structural design has developed from lightweight topology optimization design to multi-physics coupling functional structure design and intelligent structure design based on environmental excitation response. Among them, the design and additive manufacturing of multi-physics coupled functional metamaterials is an important development direction.Metamaterials are engineering materials that exhibit special mechanical, acoustic, thermal or electromagnetic properties through macro and micro cross-scale structural design. This paper describes the recent research progress in the field of aerospace structural design and additive manufacturing from the aspects of mechanical metamaterials, functional metamaterials and intelligent metamaterial components. The development trend of structural innovative design and additive manufacturing is summarized and prospected, and the broad application prospect is described.
