Due to excellent comprehensive properties such as low density, excellent corrosion resistance, and great biocompatibility, titanium alloys become one of the most important structural materials used in the biomedical area. However, relative high processing cost has significantly limited the wide application of titanium alloys as biomedical materials. In this work, we studied the microstructure in a biomedical used Ti-6Al-4V (wt.%, Ti-64) alloy manufactured by a low cost and highly efficient extrusion-based 3D printing technique using both 2D and 3D characterization technique. The microstructure inside the 3D printed Ti-64 was studied using scanning electron microscopy and transmission electron microscopy. The defect especially the distribution and the size of the pores inside the 3D printed Ti-64 was studied using Focused Ion Beam- Scanning Electron Microscopy (FIB-SEM) tomography. This work has been supported by the Seed Fund from University of Nevada Reno.
