Abstract
This paper will discuss our progress in developing surface finishing techniques for additively manufactured aerospace alloys. Additive manufacturing (AM) processes have the potential to revolutionize the art of manufacturing complex components, essentially enabling a build to print scenario where the designer has unlimited bounds. However, when printing fine featured metallic materials using powder bed (pb) approaches the surface left by the AM process are usually rough with adherent particles (20 to 75 µm in diameter) covering the entirety of the surface. In the following paper we will discuss our electrochemical finishing approach to eliminate these surface defects and finish the surface with as little material removal as possible. Furthermore, we will discuss our approach to finishing of grade 5 titanium alloy (Ti64) produced via an electron beam pb-AM approach and using various electrolytes and both as built and post hot isostatically pressed (HIPped) components.
