New Revolutionary Ideas Of Material Processing - A Path To Biomaterial Fabrication By Rapid Prototyping

The fundamentally different features of Rapid prototyping (RP) from that of conventional sintering offerus some new approaches to develop materials with excellent properties. Applying this method, porous Hydroxyapatite (Hap) ceramics, as well as the HAp-zirconia composites have been fabricated successfully. Porous hydroxyapatite (Hap) is expected to have desired mechanical and biological properties for biomedical applications. However, due to material processing problems, to date, this material can only be prepared by conventional techniques. Fuse deposition Machine is modified to fabricate Hap conventional support structure is not required three nozzle system is utilized for fabrication. Main nozzle is provided with heating arrangement. Two nozzles provided for transient Hap and solvent. Three stages heating with two lasers arrangement for gradual temperature change so transformation is faster. Primary result shows mechanical properties and porosity is as per bone structure. The micro structural characterizations such as phase purity and composition of porous BCP granules were performed and verified by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) analysis. The chemical and the microstructure information of the Fabricated Hap were investigated by FT-IR (Fourier Transform Infra-Red), SEM (Scanning Electron Microscopy), X-ray Diffraction (XRD). Result shows interconnected regular pores and uniformly distribution of Hap. There is covalent boding makes stronger adhesion to prosthetic. Using this technique, it is possible to produce scaffolds with mechanical and structural properties close to those of the natural bone and teeth. The prepared scaffold has an open, regular pattern and uniformly interconnected porous structure. Some extent problem of small Nano particle aggregate together is called Balling and product of different temperature solidify on the layer is called recasting is dominates the process. By optimizing the operating parameter these problem can be minimized. (C) 2015 The Authors. Published by Elsevier Ltd.
