Topology optimization (TO) additive manufacturing (AM) provide a complete innovation methodology for lightweight and high-performance complicated structures. This paper reviews the recent research on the integration of TO and AM

including the TO method considering AM processing constraints

the optimization method of non-uniform lattice structure. Furthermore

the integration of TO and AM is typically applied in civil aircraft structural design. Taking the structural design of hatch rocker arm and hinge arm as examples

while meeting the design indicators

the weight of hatch rocker arm and hinge arm structure were reduced by 10% and 30%

respectively. Finally

the integration of TO and AM shows obvious advantages in aerospace and other fields. However

the conventional design methods such as traditional static stiffness and static strength are mainly used

currently

and the industry application are focused on functional parts and secondary load-bearing parts. In the future

breakthroughs are needed in the fields such as fatigue-resistant design of AM structures.
