The invention relates to a device (10) for additively producing at least one component region of a component (12), in particular a component (12) of a turbomachine. The device (10) can comprise at least one component platform (16), which can be lowered and which has at least one constructing and joining zone (20) for accommodating at least one powder layer of a component material, at least one heating device (24, 28) that can be moved in relation to the component platform (16), and at least one radiation source for producing at least one high-energy beam (22), by means of which high-energy beam the powder layer can be locally fused and/or sintered to form a component layer in the region of the constructing and joining zone (20), and at least one suctioning and/or gas-feeding device (36), which is arranged on the heating device (24, 28). The device (10) can, however, also comprise at least one coating apparatus (14) for applying at least one powder layer of a component material to at least one constructing and joining zone (20) of at least one component platform (16) that can be lowered, wherein the coating apparatus (14) can be moved in relation to the component platform (16), and at least one suctioning and/or gas-feeding device (36), which is arranged on the coating apparatus (14).
