Abstract Scope |
CP-Ti has been widely used in load-bearing applications. Owing to its high Young’s modulus, it induces a stress-shielding effect in bones. To combat the stress shielding effect of Ti solid bio-implants, porous structures such as lattices or TPMS are fabricated using additive manufacturing technology. Despite manufacturing implants with the desired mechanical properties, the bio-inert nature of CP-Ti necessitates the addition of a second bio-active phase. Chicken eggshells are daily food waste, which poses disposal risks. On the other hand, it contains Calcium Carbonate, which is bio-active, bio-resorbable, osseoinductive, and antibacterial bio-ceramic. The biodegradable nature of eggshells did not allow its use as an individual implant material. Hence, this research aims to produce a CP-Ti lattice by Laser Powder Bed Fusion (LPBF)-based additive manufacturing, which infiltrated eggshells and produced an interpenetrating phase composite. The mechanical and biological properties of the composites were characterized to validate its application for load-bearing implants. |
