7. Outlook

In summary, electropolishing is an old industrial process that is finding renewed interest in the finishing of metal parts produced by additive manufacturing. This has led to the emergence of innovative processes, based on the application of bipolar pulses and the use of unconventional electrolytes.

Pulsed and reverse-pulsed polarization is probably the key to reducing the impact of electrolytes, while improving the quality, uniformity and speed of the process, thus supporting its industrial transfer towards the objective of improving surfaces at lower cost. It is this combination (polarization wave and innovative chemistry) that machine manufacturers rely on. The electropolishing of manufactured parts on surface treatment lines is a conceivable prospect for many components, if we consider the progress made on generators on the one hand, and simulation tools on...
