Compressive properties of novel hybrid-dimensional gyroid lattice structure

This work proposed a novel hybrid method based on the three-dimensional gyroid lattice structure and twodimensional honeycomb lattice structure. We choose a commercial stereolithography (SLA) printer to fabricate the lattice samples with 405 nm photosensitive resin material. Axial quasi-static compression is selected to test the mechanical properties. According to the experimental results, the multiple deformation behaviors and reinforcement of stress response at the post-plateau stage are observed in hybrid lattice samples. By the proportion of substructure, the compressive strength and energy absorption of the hybrid-dimensional lattice can be tailored, which is suitable to act as an effective energy absorber for various applications.
