Abstract

Design of porous scaffolds is a critical issue in orthopaedic applications. Porous biomaterial scaffolds are suitable for repairing the damaged bones. They promote proliferation and osseointegration of bone tissues. To fabricate the porous scaffolds, Additive Manufacturing (AM) techniques have been widely used. Modeling and Finite Element Analysis (FEA) allows investigating the mechanical and biological behaviour of patient specific implants at reduced cost. In this study, modeling of Hollow Cube and Truncated Hexahedron (ThH) unit cells has been done using the SolidWorks 2016 CAD software and FEA of their compressive strength has been done using the Abaqus 6.14 FEA package. The compressive strength of various structures based on these two unit cells have been analyzed for different strut size for the biocompatible grade 5 titanium alloy (Ti-6Al-4V). Compressive strength of 162 MPa for THH 2 for strut size of 0.5 found to be in desirable range of cortical bone.
