Method for producing a component having a cooling channel system

Abstract

The invention provides a method for producing a component (100) having a cooling channel system, the method comprising: building a first portion (10) of the component (100) by means of the additive, integrally bonded application of a build material; and—introducing a first cavity (11) having an opening into the first portion (10) of the component (100). The method is characterized in that it also comprises: covering the opening of the first cavity (11) in the first portion (10) by means of a covering part (13);—building a second portion (20) of the component (100) by means of the additive, integrally bonded application of the build material, the build material being applied to the first portion (10) and to the covering part (13); introducing a second cavity (21) having an opening into the second portion (20) of the component (100); and—introducing a connecting channel (90), (90a) into the component (100) by means of material-removing machining in order to form the cooling channel system, the connecting channel (90), (90a) connecting the second cavity (21) of the second portion (20) to the first cavity (11) of the first portion (10) of the component (100).
