In recent years, the technology of lattice structure has developed rapidly with the development of additive manufacturing. It has shown great potential in the application of structural and functional integration technology. It can be used as a good design carrier for multi-function, and it can realize the organic integration of various functions such as bearing,heat proof, stealth and variant. However, some key technologies have yet to be broken, and so far there has not been a large scale application of the lattice structure in the aircraft. Combined with the requirement of aircraft structure/function integration, the manufacturing technology, performance characteristics and typical applications of dot matrix structure are reviewed, and the reasons for the application of lattice structure are analyzed and discussed from the aspects of structure design, manufacturing process and performance evaluation.
