Abstract: The wide application of energy absorption structure in human life has caused a large number of scientific research and frontier technological development on energy absorption characteristics. Through the choice of nature for a long time, some special structures of various animals and plants give the designers inspiration, and the bionic energy absorption structure has been studied extensively. In this process, the additive manufacturing technology is flexible, capable to manufacture complex structures, and use additive materials, so it becomes an ideal choice to solve the needs of lightweight and complex structures. However, at the present stage, the review research on the field of bionic energy absorption structure is limited, and the systematic summary is relatively lacking, which leads to the insufficient understanding of the development status and problems of the whole technology. This paper mainly on bionic thin wall structure, bionic plate structure, bionic cell structure and bionic building structure corresponding to the structure and performance of animals and plants, this paper is based on the additive manufacturing technology in the field of bionic energy absorption structure research status, in order to future the development of bionic energy absorption structure to provide certain reference.
