Though Titanium and its alloys are important materials for bioimplant application, however, the relatively higher Young's modulus and bio-inertness are the real problems associated with the decreased lifetime and root cause of premature failure of the implant. Though research efforts on the development of low Young's modulus titanium-based alloy are successful, however, cost of those alloys and poor mechanical properties cause hindrance on increased popularity of these alloys. Porous titanium is the recent advancement of the evolution of titanium-based alloy. Though conventional techniques have successfully been applied for the development of porous titanium, however, developing porous implants with the desired size, shape and distribution of porosity and with interconnected porosities is a real challenge. Laser additive manufacturing (LAM) is the advancement in this regard for the development of porous titanium implant with the presence of interconnected porosities. Though LAM has been applied, however, the development is far away from the optimum design of porous implant for desired applications. Hence, in the proposed investigation, an extensive study of designing the titanium-based implant will be made with the desired shape, size and distribution of porosities. LAM would be applied for the fabrication of porous implants. Auxetic metamaterial would be considered for achieving better strain energy density at the adjacent bone of implant for improved bone growth. Finally, the fabricated implants will be coated for improving osseointegration.
