Additive manufacturing allows for customizable geometries allowing for such benefits as weight reduction and the creation of fully functional parts such as bearings in one processing step. In this work, the effect of part geometry of powder bed fusion additively manufactured Ti-6Al-4V with similar volumes but different part geometry (cylinder, cuboid, cone, and dodecahedron) was studied with respect to the resulting microstructure and porosity. X-ray microcomputed tomography (micro-CT) was conducted to determine the effect that the difference in shape had on the size and morphology of the porosity. The microstructure was examined to determine the effect that the reduction and expansion of the layer area with respect to the formations of heat affected zones. Laser profilometry and micro-CT was used to determine the effect of part geometry on the surface roughness and dimensional accuracy.
