Abstract
The invention relates to a method for controlling an irradiation system (), the irradiation system () being used in a device () for the additive manufacturing of three-dimensional workpieces and comprising at least three irradiation units (-), the method comprising the following steps: a) defining an irradiation region (-) for each of the irradiation units (-), the irradiation regions (-) each comprising a portion of an irradiation plane () which extends parallel to a carrier () of the device (), and the irradiation regions (-) being defined such that they overlap in a common overlap region (); b) irradiating a raw material powder layer on the carrier () to produce a workpiece layer; c) arranging a further raw material powder layer on the already jetted raw material powder layer to produce a further workpiece layer. d) The invention also relates to a device for performing this method.
