Track: Manufacturing

Abstract

The fabrication of porous scaffolds is a significant challenge in orthopedic applications. Bone fractures can be repaired using porous biomaterial scaffolds. In addition to promoting bone growth, they also aid in the tissues' ability to osseointegrate. Porous scaffolds are increasingly being made using Additive Manufacturing (AM) methods.  Modeling and finite element analysis (FEA) allow for more affordable exploration of the mechanical and biological behavior of patient-specific implants. In this study, we have used the CAD programme Creo to construct a scaffold lattice structure with three different unit cells triangular, hexagonal, and octagonal, and finite element analysis (FEA) of the compressive strength of these unit cells has been carried out using the Abaqus software. Compressive strength of lattice structures based on these three-unit cells was studied for the biocompatible PLA thermoplastic polymer with a strut size of 2mm.
