Abstract

Bio-inspired structures based on triply periodic minimal surface (TPMS) architectures have been widely known in the literature [1]. These structures represent a significant advancement in the design of novel materials with superior mechanical properties. Inspired by natural geometric forms, TPMS-based designs offer exceptional opportunities to create materials that closely mimic the complex microstructures found in biological systems. These TPMS patterns exhibit key mechanical properties, including lightweight characteristics, high porosity, and impressive energy absorption capabilities, making them highly promising for various engineering applications. This talk devotes a review on modeling and fabrication of bio-inspired TPMS structures, including rotating TPMS-G, IWP, and P types [2,3]. We then discuss their mechanical properties numerically and experimentally. Additionally, several extensive studies on TPMS-based bioinspired structures were addressed [3]. Finally, we provide insights into considerations and recommendations for further advancements.
