Abstract: The invention relates to a device for producing three-dimensional workpieces, The device comprises a carrier for receiving raw material powder and a radiation unit for selectively radiating the raw material powder applied to the carrier with electromagnetic radiation or particle radiation in order to produce on the carrier a workpiece made of the raw material powder by a generative layering construction process. The device also comprises a vertical movement means, which is designed to move the radiation unit vertically relative to the carrier, and a cylinder construction wall, which extends substantially vertically and which constitutes a lateral delimitation for the raw material powder applied to the carrier, wherein the cylinder construction wall is designed to increase its vertical height during the construction process.

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.
