3D printed sandwich beams with bioinspired cores: Mechanical performance and modelling

Triply periodic minimal surface (TPMS) based cellular structures have drawn increasingly attention due to their mathematically controlled topologies and promising mechanical properties. Here, we combine 3D-printing technique, experiments, theoretical formulation and numerical simulation to investigate a novel class of lightweight sandwich structures with TPMS cores. Sandwich structures with Primitive, Neovius and IWP core topologies are designed...
