Abstract

The invention relates to a method for producing a component (2) comprising at least one channel (4) which extends into the component (2). The method has a step A in which an assembly (1) is produced in an additive manufacturing process, comprising the component (2) and at least one cathode (3) that extends into the channel (4) of the component (2); a step B in which the component (2) is electrochemically post-processed by producing a closed current circuit across the component (2) as the anode and the cathode (3) using an electrolyte medium, preferably by positioning the assembly (1) in an electrolyte immersion bath and/or by flushing the channel (4) with an electrolyte; and a step C in which the cathode (3) is removed from the channel (4).
