Electropolishing is a state-of-the-art surface finishing process for biomedical parts, devices, coronary stents, cardiovascular and orthopedic body implants. The electropolishing phenomenon is characterized by the elimination of surface roughness and by the absence of crystallographic and grain-boundary attack, resulting in the production of bright and glossy metal surfaces. Furthermore, due to its simplicity and ability to be used for polishing complex structures, electropolishing is a promising method for post-processing of the additively manufactured components. Nevertheless, the major challenge of the process is its effectiveness.
