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.

Production of three-dimensional workpieces by means of a plurality of irradiation units

A powder application arrangement for use in an apparatus for manufacturing work pieces by irradiating powder layers with electromagnetic radiation or particle radiation, the powder application arrangement comprises a carrier adapted to receive layers of a raw material powder and a work piece made of the raw material powder by a generative layer construction method. The powder application arrangement further includes a powder application device configured to deposit the raw material powder onto the carrier At least one camera is attached to the powder application device in such a position that it is capable of acquiring images of at least one of a surface of a raw material powder layer applied onto the carrier by means of the powder application device and a surface of the work piece made of the raw material powder by a generative layer construction method while the powder application device is moved across the carrier.
