Biological materials have been selected and optimized progressively through evolution. As a result, they often exhibit excellent functionality and remarkable adaptability owing to their meticulous microstructures and interfaces. In this study, several 3D microstructures of selected biological materials, e.g., termite nests, avian bones, antlers, cuttlebones, natural photonic crystals, were reconstructed by the micro-CT scan samples. These microstructures perform superior mechanical properties in terms of lightweight, high material utilization, and energy absorption. We systematically generated vast amount of bio-inspired ordered/disordered 3D surface structures by various theories and numerical analyses, such as triply periodic minimal surface (TPMS), spinodal decomposition, and reaction-diffusion models. We also exploited additive manufacturing alongside finite element simulation to elucidate the mechanisms between bio-inspired structures and their mechanical properties. This framework opens a new avenue on bio-inspired structural materials by design.
