Abstract
Recent advances in additive manufacturing have shown that porous cellular architectures can help reduce stress shielding in implants. This study used finite element analysis (FEA) to design wedge-shaped implants with lower elastic modulus, incorporating triply periodic minimal surface structures-specifically Gyroid and Schwarz-P types. Designs considered selective laser melting constraints, and produced using Ti6Al4V with five porosity levels (55-75%). Compression simulations revealed that increasing porosity decreased both Young's modulus and yield strength. The 75% porous Gyroid structure had the lowest Young's modulus (12.81 GPa), closest to that of natural bone. These results suggest FEA can effectively guide the design of bone-mimicking implants.
期刊介绍：
The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
