| Abstract Scope |
The as-printed surface of 316L stainless steel parts produced via laser powder bed fusion (L-PBF) is tortuously rough and chemically heterogeneous. Such characteristics lead to variability in the materials surface properties such as susceptibility to local corrosion. Torturous as-printed surfaces have led to many polishing techniques being applied to remove these rough surface features. The present work will show how the as-printed surface of L-PBF 316L is formed, explain what controls the chemical heterogeneities, and explore a process to remove the tortuous surface in dry electrolyte polishing. The presentation will focus on the dry electrolyte polishing as it is a relatively new technique for polishing additively manufactured parts and can produce smooth surfaces with minimal material removal.
