Additive manufacturing (AM) technology and three-dimensional (3D) lattice structure technology are important routes toward lightweight multifunctional aerospace equipment. This paper reviews the recent research progress on additive manufactured 3D lattice structures and their design methods
focusing on the status and trends in the following aspects: engineering application of additive manufactured 3D lattice structures
design method of lightweight and multi-functional 3D lattice structures
multi-scale numerical simulation and topology optimization method of 3D lattice structures
mechanical performance evaluation and characterization method of 3D lattice structures for additive manufacturing. Finally
the development trend of material–structure–multifunction integrated design of additive manufactured 3D lattice structures is prospected.
