Abstract: We describe a process chamber, an apparatus, a modular system, a method, a safety device, a positioning system and a system for producing a three-dimensional workpiece and/or for use thereof when producing a three-dimensional workpiece. The process chamber for producing the three-dimensional workpiece via an additive layer construction method comprises: a material supply unit comprising a substantially ring-like shaped end portion at a first side of the process chamber, wherein the material supply unit is adapted to supply, via the end portion, material to a carrier on which the material is to be processed by the process chamber for producing the three-dimensional workpiece, and an opening at the first side of the process chamber for processing, by the process chamber, the material supplied on the carrier in order to produce the three-dimensional workpiece, wherein the substantially ring-like shaped end portion surrounds the opening.

Abstract: A process chamber housing for an additive manufacturing apparatus comprising a process chamber with a bottom, a ceiling, and sidewalls jointly enclosing a volume of the process chamber, with a gas inlet in a front wall and a gas outlet in a rear wall of the sidewalls. The gas inlet and outlet are positioned at opposite sides of an opening in the bottom and face each other, which allows for an improved removal of smoke out of the process chamber if the gas inlet has a width wi, the opening has a width ws, and the gas outlet has a width w0, such that at least one of the relations (i) wi≥ws±4 cm and w0≥ws±4 cm; (ii) wi≥ws and/or w0≥ws; and (iii) wi≥ws+1 cm and/or w0≥ws+1 cm is satisfied.

Abstract: An apparatus including a process chamber accommodating a carrier for receiving a raw material powder. An irradiation device of the apparatus is configured to selectively irradiate electromagnetic or particle radiation onto the raw material powder on the carrier in order to produce a work piece by an additive layer construction method, wherein a transmission element allows the transmission of the electromagnetic or particle radiation into the process chamber. The apparatus further includes a gas inlet and a gas outlet for supplying and discharging gas to and from the process chamber which are configured to generate a protective gas stream for protecting the transmission element from being contaminated by impurities present in the process chamber. The gas inlet includes a gas permeable, porous component forming a gas inlet area.

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.
