Abstract

A method for manufacture of a complex component includes construction of the component from a metal material in an additive manufacturing method with at least one cavity segment that has a cavity open on at least one side and defined by an interior surface of the component, formation of an auxiliary electrode during construction of the component, formation of one or a plurality of supporting structures that connect the auxiliary electrode to the interior surface of the component during the construction of the component, electrical insulation of the auxiliary electrode from the interior surface by separating the supporting structures from the interior surface or from the auxiliary electrode, and performance of an electro-polishing of the interior surface in an electrolyte bath by connecting the component and the auxiliary electrode to different poles of an electric voltage source.
