Abstract. Additively manufactured components enable the flexible design of parts with customised features. Consequently, additive manufacturing already has a high degree of industrial application. A limiting factor of this technology is the high surface roughness that results from layer-to-layer processing, such as staircase effect, spatters and balling effect. A possibility for the post-processing of additively manufactured components is Jet-ECM. By applying Jet-ECM, additively manufactured components can be selectively finished and microstructured. The material is removed in an electrolyte jet that is moved laterally across the workpiece. Due to the anodic metal dissolution, metals can be processed regardless of their mechanical properties. Based on the results, it was determined that the roughness can be reduced with increased nozzle velocity. In addition, the removal depth can be achieved with a higher number of traversing frequency or with a decreasing nozzle velocity.
