Abstract
The application relates to a device for producing three-dimensional workpieces, the device including: a structural surface designed to receive a molding compound; and an irradiation arrangement designed to selectively irradiate the molding compound on the structural surface with electromagnetic radiation, in order to produce a workpiece by means of generative layer construction, where the irradiation device comprises a plurality of irradiation units, the irradiation units being designed to irradiate an individual region of the structural surface respectively associated with the irradiation units, and where the beams emitted by the irradiation units respectively have a cross-sectional surface corresponding to between approx. 2% and approx. 170% of the surface of the respectively associated individual region. The application also relates to the use of such a device and to a method for producing three-dimensional workpieces by means of such a device.
