Abstract: Strut-based lattice structures exhibit exceptional performance in load-bearing and energy absorption. With the advancements and improvements in additive manufacturing methods, the utilization of these structures has become more attractive and practical. This study aims to investigate the deformation modes and mechanical properties of hybrid layered lattice structures based on the octahedron unit cell. Twelve different structures, including uniform and hybrid layered configurations of the three unit cells, are fabricated using the Masked Stereolithography method. The behavior of each of the twelve structures under quasi-static compressive loading are experimentally examined. The results demonstrate the significant impact of hybrid layered design on the mechanical properties of these lattice structures. Furthermore, among all the structures studied, the inclusion of a strut oriented parallel to the compressive loading direction showed the highest energy absorption performance. Additionally, the findings of this research can be important and inspiring for the fabrication and design of lattice structures at various scales.
