Abstract Scope |
Porosity on metal implants has been proven to enhance osseointegration in orthopedic applications in vivo. Additive manufacturing (AM) offers the freedom of designing desired pore morphology to achieve the required porosity on implant material in a single operation. The strength of such designed porous structures depends on overall volume fraction porosity, pore-morphology, pore size, and pore-pore connectivity. Since implants are under constant loading conditions in vivo, it is essential to evaluate the strength of porous metals under compressive and shear loading. Ti6Al4V is the most widely used material for load-bearing orthopedic implants. Although CpTi has higher biocompatibility than Ti6Al4V, it shows lower strength than the latter. Our work focuses on evaluating the effect of reduced Al and V contents in Ti6Al4V towards mechanical and biological performance compared to that shown by Ti6Al4V and CpTi, respectively. |
