dc.description.abstractAdditive manufacturing is turning out to be one of the prominent domain of research in recent times due to its ability to fabricate complex structures. The technique is extensively utilised in numerous applications, ranging from fabrication of clinical products to aerospace components. The drawbacks put forth by conventional manufacturing techniques in fabricating complex near net shape structures can be mitigated by additive manufacturing techniques. The ability to fabricate components with a trivial lead time and material wastage is another highlight of the technique. Additive Manufacturing techniques have phenomenal benefits, where complicated porous structures can be fabricated rapidly. An animal musculoskeletal system demands specific features for the implant materials for rejuvenation of lost body functions. The porous network have significant contributions towards biomechanical rejuvenation of the musculoskeletal system. The bone tissue – implant material interaction possess significant dependency on the surface properties of Ti-6Al-4V biomedical implant. In the present research, the effect of powder recycling on the surface properties of the implant material fabricated by Electron Beam Melting (EBM) were investigated. The investigation was aimed to formulate an idea about the advantageous and disadvantageous effects of powder reuse in EBM. Microstructure of the implant, surface chemistry and geometry were characterized. The notable characterization techniques used were Scanning Electron Microscope, X-Ray Photoelectron Spectroscopy, X-Ray microtomography and Confocal Microscopy. It was evident from the analysis that the overall microstructure of the implant samples exhibited trivial variation with respect to powder recycling. The lattice and solid regions in the implant samples were found to have a notable increase in oxygen content. The implant geometry and surface roughness were found to exhibit a feedstock induced variation.sv
