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.
