Plasma electrolytic Polishing (PeP), an environmentally friendly polishing process based on high DC voltage and aqueous electrolytes, does not require a shaped tool and has the capability of achieving surface qualities of Ra ≤ 0.02 Ám in metallic parts. New requirements for post-processing of additively manufactured parts exceed those of its conventional applications of deburring and gloss enhancing. Targeted at typical AM parts incorporating complex shapes with large surfaces and deep cavities, PeP faces new challenges. Approaches of Jet-PeP (a nozzle-based process in contrast to the conventional vat-based), selective PeP (local polishing of large parts) and hybrid PeP processes with additional ultrasonic vibration push the boundaries towards overcoming these obstacles. The paper introduces the fundamentals and shows latest results using the new approaches.
