Selective Laser Melting (SLM) is a powerful technique that enables us to produce complex shapes of implants customized for patients. Besides, all of the physicochemical effects on the structure of metal alloy implants must be taken under the control during the production such as polydispersity of the nanostructured morphologies inside of the incident metal alloy powders, orientation of the samples according to the growth axis, production temperature, the cooling methods of the produced implants, etc. In the present study, first case Small Angle X-Ray Scattering (SAXS) method was used on Ti-6Al-4V implants (produced by SLM technique) to nanostructurally investigate the orientation effect. Structural controls and characterizations leads more successful implant production related with nanoscale nucleations, grain aggregations and uniform distributions. So, the biophysical and biochemical properties of high corrosion resistive Ti-6Al-4V alloy implants would be able to be developed.
