摘要：

Light-weight photopolymer Kagome lattice materials are manufactured based on the ideally suited 3D-printed technology. The compression properties and deformation pattern are experimentally and numerically investigated, exploring the failure mechanism and energy absorption characteristics of three cores variants. The effects of core-geometry variables on the compression behaviors are analyzed. The different dominated failure is respectively explored for three core-variants. The damage of lattice cores can be well verified by the micro-defects observed. All suggest that the grid-reinforced lattice cores effectively inherit the compression-tolerant and energy-absorbing capability of single-layer cores. These Kagome lattice cores can be considered as potentially reusable energy-absorbing materials.
