Single-parameter mechanical design of a 3D-printed octet truss topological scaffold to match natural cancellous bones

• A single-parameter design method that accurately predicts the mechanical properties of octet truss scaffolds was developed. wide-range adjustment Young's modulus and yield strength achieved. The made different polymers with varying d / Ø were mapped. ranges suitable match defferent natural cancellous bones suggested. Designing a scaffold matching to optimize bone regeneration is required in tissue engineering. present work developed for topological achieve accurate prediction flexible its Young’s strength. theoretical model formulated normalized by single parameter ( ) proposed further validated uniaxial compression tests FEA simulations. On basis model, mapped, results showed could predict porosity, specific area, strength, adjust wide range. can be used selection constituent materials obtain desired properties, has application prospects fields engineering regenerative medicine.
