However, lattice structures often exhibit anisotropy because of the non-uniform distribution of the constitutive material in the tessellated unit cells, leading to variations in mechanical response based on loading direction. Loads applied to a lattice bone scaffold may not align with the main axes of the arranged unit cells. Therefore, optimizing the unit cell orientation angle seems necessary for achieving superior mechanical performance. This study investigates the mechanical properties of Gyroid-based lattice structures with varying unit cell orientations. Numerical analyses were conducted on five Gyroid-based lattice models with different cell orientations, and their compressive Young’s moduli were determined. These findings were validated through mechanical compression experiments on corresponding 3D printed samples. The results indicate that the compressive Young’s modulus in the least stiff direction is 18.99% lower than that along the stiffest direction. This is an advantage for the development of Gyroid-based bone regeneration scaffolds, particularly in scenarios where loading directions are not known in advance.}, number={1}, publisher={Kerim ÇETİNKAYA}
