Taking the internal structure of additive manufacturing models as the research object,this paper explores the generation method of lattice models for additive manufacturing around the lightweighting of the structure.Taking the prosthetic limb model as an example,by analyzing the relationship between lattice unit structure and mechanical properties,a performance balanced lattice structure type is established,and then skeleton lines are used to drive the design of lattice unit model.Finally,a lightweight lattice model is established based on mixed geometry methods.
