面向增材制造的非均匀点阵结构综述OA北大核心CSTPCD

Benefiting from the development of additive manufacturing(AM)technology,the manufacturing difficulty of highly complex structures such as porous structures,topology-optimized structures,and biomimetic structures has been reduced.AM has promoted the research progress of highly complex structures.As a typical porous structure,the lattice structure has excellent performance and good designability,which results have been applied in many fields such as aerospace,biomedicine,and automobile manufacturing.Comparing with the uniform lattice structure,the non-uniform lattice structure can exert the potential of the structure and material better,so it has the more application value in practice.In this paper,the research status and development trend of the design methods and manufacturing styles of non-uniform lattice structures are explained,and the non-uniform lattice structures are reviewed in detail.At the same time,the challenges of current research and the future research of lattice structures is proposed.
