As the engine technology of the third industrial revolution

selective laser melting (SLM) has broken through the manufacturing limit of traditional processing technology and provided the possibility for the structural design and manufacturing of high-performance components in aerospace

medical

automotive and other fields. Lattice structure has been widely used in various disciplines due to its high specific strength

high specific stiffness

low coefficient of thermal expansion and high specific surface area. Based on SLM technology

combined with the innovative manufacturing mode of material-structure-performance integration

lattice structure has become an effective solution for lightweight

highperformance and multi-functional design and manufacturing proposed by multidisciplinary fields at this stage. In this paper

the types of SLM-manufactured lattice structure

process synergy and design optimization methods are introduced in detail. The mechanical properties and energy absorption capacity of the lattice structure are analyzed; The applications of several typical functional lattice structures in aerospace

medical and automotive fields are described

and their future development in engineering applications is prospected.
