dc.description.abstract Nature’s evolution of a billion years has advanced flawless functionality in limitless optimized structures like bone structural adaptation in various physiological behaviours. In this study, porous structures are designed and fabricated from the nature-inspired trabecular bone microarchitecture. A three-dimensional (3D) model of the porous trabecular architecture from the compressive proximal zone of the femoral head was constructed using the micro-computed tomography scanning tool. The model was modified to get porous structures of different volume fractions varying from 20 to 40% with an increment of 10%. The obtained porous structures were 3D printed and analysed for deformation-resistant behaviour. Quasi-static compressive loading was performed at different strain rates (0.001–1 s−1) to get an insight into lightweight, high strength structural behaviour. Mechanical parameters, such as specific modulus, specific strength and specific energy absorption, were analysed for the optimal volume fraction. The original volume fraction (30%) of the trabecular bone shows the highest value of mechanical parameters. This study can help engineers to select and design lightweight porous structures with high energy-absorbing capacity, mimicking the desired architecture and porosity available in nature.
