Investigating mechanical properties of 3D-printed grid scaffolds for orthopedic applications

This study investigates the mechanical behavior of grid scaffolds with different void sizes under compression. The scaffolds are fabricated using 3D printing techniques, and their performance is evaluated through simulations and experiments. Smaller void sizes result in scaffolds with higher Young's modulus and load-bearing capacity, indicating increased stiffness and the ability to support heavier loads. Energy distribution analysis reveals the roles of kinetic energy and inelastic deformation in energy dissipation during compression. Scaffolds with smaller void sizes exhibit longer elastic stages and higher energy storage capacity, indicating their resistance to deformation and ability to maintain shape under compressive forces. Scaffolds with smaller void sizes also demonstrate a more uniform stress distribution throughout the structure, enhancing their load-bearing capacity. These findings highlight the importance of scaffold design and fabrication processes for optimizing mechanical properties. The study provides valuable insights for scaffold applications in engineering and biomedicine, guiding future research towards optimizing scaffold performance for specific use cases.
