Abstract: Lightweight design is exceptionally needed in sectors including aerospace, automobile, and medical care because of its superiority in reducing energy consumption and enhancing performance of structures. Additive manufacturing can build complex structures by adding materials layer by layer. Today, the integration of lattice structure and additive manufacturing has shed new light on the design and manufacturing of high-performance lightweight structures. However, the lattice structure based on additive manufacturing is often subjected to cyclic loading in service and thus exposed to fatigue damage. The coordination between lightness and anti-fatigue property has yet been achieved in research and development of structures employed in the new generation of aerospace industry. In this review, an introduction of the methods utilized in design and manufacturing of lightweight structures is presented, and a summary of techniques in on the subject is given. After that, a review of the research on fatigue properties of additive-manufactured lattice structures is offered, and it is figured out that the integration of design and manufacturing is feasible to ensure the anti-fatigue property of these structures.
