Development and Testing of Polyurethane based Composites using Rapid Prototyping Techniques for Biomedical Applications-A Review

The fused deposition modeling (FDM) can be used to develop physical model from three dimensional CAD models. Basically FDM uses a thermoplastic filament, which is heated to its melting point and after that extruded, layer by layer to create a three dimensional object [1]. However this technique is still in front of some problems for its application in bio-compatible polymer based composite due to lack of information. The present paper reviews the use of FDM process for development of biocompatible composites. The present paper focuses on the application of Polyurethane-Titanium Composite as bio compatible material. The addition of titanium significantly increases the mechanical properties similar to high strength to weight ratio, durability, fatigue strength, hardness, corrosion and wear resistance of the composite. Therefore the Polyurethane-Titanium Composite can be usefully for medical applications. (C) 2019 Published by Elsevier Ltd.
