| Abstract Scope |
Bone’s microstructure features a multiscale functional gradient and optimized material composition, enabling structural support, mobility, and adaptation to mechanical stress. Bone replacement implants are typically made from metal alloys with mechanical properties that differ from bone, often leading to stress shielding. This mismatch can reduce implant lifespan and lead to costly revision surgeries, negatively impacting patient quality of life. To address this challenge, this study uses additive manufacturing to create gyroid structures from PEKK via fused deposition modeling, a high-performance polymer that may better match bone properties. This study examines the mechanical behavior, focusing on compressive and biaxial loading under bio-relevant stress conditions. The research aims to elucidate the deformation mechanisms under these loading scenarios. In particular, the gyroid relative densities characterized are between 80% and 30%, and a graded transition between them. Understanding how relative density, grading, and printing orientations affect mechanical behavior will inform strategies to optimize performance. |
