Porous implants reduce stress-shielding within implanted bones. Body-centered-cubic (BCC) and cubic cellular structures were investigated in this study to mimic bone properties. For this purpose, CAD models (7 BCC and 7 cubic) with 50% to 80% porosity were designed and 3D-printed. Morphological analysis revealed minor dimensional deviations between the CAD and the 3D-printed models. Using finite element analysis, experimental approach, and regression analysis, an ideal porosity range to mimic the mechanical properties of bone has been established. Lattices with a porosity of 60%–65% and 50%–55% for cubic and BCC, respectively, can emulate the mechanical properties of cortical bones. [ABSTRACT FROM AUTHOR] |
