The present invention relates to a method for the additive manufacture of components (2), wherein a pulverulent or wire-shaped metal construction material is deposited on a platform (4) in layers, melted using a primary heating device (7), in particular using a laser or electron beam (14), and is heated using an induction heating device (8), which has an alternating voltage supply device (9) with an induction generator (16) and at least one induction coil (10) which can be moved above the platform (4). The induction generator (16) is controlled such that the induction generator is driven with a different output at different specified positions of the at least one induction coil (10). The invention additionally relates to a device, to a control method, and to a storage medium.
