Abstract

A device for additive manufacturing of components by selective irradiation of a powder bed, having a processing chamber—in which at least one powder bed chamber and at least one radiation source are arranged such that the radiation source can irradiate a powder in the powder bed chamber, and wherein the device includes at least one induction coil, so that a component which is produced by irradiation of the powder bed can be at least partially inductively heated, and wherein the induction coil is movable relative to one or more powder bed chambers. A method for additive manufacturing of components by selective irradiation of a powder bed, in which method the component being manufactured is inductively heated at the same time, wherein the position of one or more induction coils for inductive heating is determined and adjusted based on the geometry of the component to be produced.
