Device and method for additively producing at least one component region of a component

A device for additively producing at least one component region of a component of a turbomachine, comprising:

• at least one coating apparatus for applying at least one powder layer of a component material onto at least one build-up and joining zone of at least one component platform, which can be lowered, wherein the coating apparatus can be moved in relation to the component platform;
• and
• at least one suction device for suctioning of process waste gases and/or particles directly from the at least one build-up and joining zone to at least one overflow tank,
• wherein the coating apparatus comprises at least one suction channel or at least one suction pipe with at least one suction opening oriented in the direction of the component platform, wherein the suction channel or the suction pipe is arranged in such a way that, in a predefined standstill position of the coating apparatus outside of the component platform, the suction channel or the suction pipe is operatively connected to the suction device for diverting a gas flow and/or a particle flow directly to the at least one overflow tank, and
• wherein in each case, the suction channel or the suction pipe has a first and a second end, wherein the first end is designed to face the suction device, and comprises at least one opening and, in the predefined standstill position of the coating apparatus, the opening comes into alignment at least in part with at least one opening of the suction device, such that the first end is docked with the at least one opening of the suction device.
