PugazhenthiAbstractEvery year, more than 10 million people have gone through orthopaedic surgery for repair or replacement of bone. Among these, 75% of patients are in a need to re-surgery due to improper implant sublimation replacement because of material failure and improper setting of the replaced materials. The implant materials need to be biocompatible with tissue growth and it should have good mechanical property. In this research work aims to produce a biocompatible polymer-based 3D scaffold models with zero defect and long-term sustainability with appropriate mechanical properties. The Additive Manufacturing Technique (AMT) offers better 3D scaffold models with near to zero tolerance. In this research work, UHMWPE polymer composite is fabricated and utilized to print the 3D scaffolds. The dimensional error and porosity of the fabricated 3D scaffolds are measured using the Scanning Electron Microscopy (SEM). The biocompatibility of the fabricated 3D scaffolds is ensured using MTT assay. The mechanical property of the UHMWPE polymer composite and its 3D scaffolds are determined. The better 3D scaffold is suggested to the medical society in the aspect of dimensional error and mechanical behaviour.
