Pulse voltage electropolishing of micro-textured surface fabricated by selective laser melting in deep eutectic solvents

Aluminum samples were additive manufactured with different laser conditions, such as the scan speed, hatch distance, scan interval, and laser power. The effects of various laser conditions on the electropolished surface were studied. It was found that the laser power was of critical importance for the electropolished surface quality. This is because the final polished surface is closely related to the initial surface quality which was mainly determined by the applied laser power.
