Title: MULTIPLE COIL ARRANGEMENT FOR A DEVICE FOR GENERATIVE PRODUCTION OF COMPONENTS AND CORRESPONDING PRODUCTION METHOD
Abstract:
The invention relates to a device for the generative production of components (4) by means of selective irradiation of a powder bed (6) having a working space (1) in which at least one powder bed chamber (3) and at least one radiation source are arranged, such that the radiation source is able to irradiate a powder in the powder bed chamber (2), and wherein the device comprises at least one induction coil (3, 13), such that a component that is generated by irradiation (7) of the powder bed can be at least partially inductively heated, and wherein the induction coil (3, 13) is movable relative to one or more powder bed chambers (2). The invention further relates to a method for the generative production of components (4) by means of selective irradiation of a powder bed (6), in which method the component produced (4) is inductively heated at the same time, wherein, on the basis of the geometry of the component to be produced, the position of one or more induction coils (3, 13) for the inductive heating is determined and set.
