    摘要： An unpacking device for use in an apparatus for producing a three-dimensional work piece by irradiating layers of a raw material powder with electromagnetic or particle radiation, the unpacking device comprises a holding device which is configured to hold a building chamber arrangement. The building chamber arrangement comprises a building chamber accommodating a carrier, wherein the carrier is configured to receive a three-dimensional work piece produced from a raw material powder by an additive layering process. An engagement unit of the unpacking device is configured to engage with the carrier of the building chamber arrangement. A moving mechanism is configured to cause a relative movement between the building chamber and the engagement unit with the carrier engaged therewith so as to allow a separation of the carrier with a three-dimensional work piece received thereon from the building chamber. Finally, the unpacking device comprises a raw material powder removal mechanism which is configured to cause at least one of a vibration and a rotation of the engagement unit with the carrier engaged therewith so as to remove residual raw material powder from the three-dimensional work piece received on the carrier.

    摘要： 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.

    摘要： A device for calibrating an irradiation system of an apparatus for producing a three-dimensional work piece includes a control unit to control the irradiation system so as to irradiate a radiation beam onto an irradiation plane according to a calibration pattern. The device also includes a sensor arrangement arranged in the irradiation plane to output signals to the control unit in response to being irradiated with the radiation beam according to the calibration pattern. The control unit generates a digital image of an actual irradiation pattern produced by the radiation beam incident on the sensor arrangement based on the signals output by the sensor arrangement, compares the digital image of the actual irradiation pattern with a digital image of a reference pattern so as to determine a deviation between the actual irradiation pattern and the reference pattern, and calibrates the irradiation system based on the determined deviation between the actual irradiation pattern and the reference pattern.

    摘要： The invention relates to a control method for controlling a multi-beam apparatus having one or more beam sources for producing a plurality of beams of a system for manufacturing a three-dimensional workpiece by means of an additive layer construction method, in which method a material that can be solidified in order to manufacture the three-dimensional workpiece is applied in layers to a surface of a carrier and the material that can be solidified is solidified by the plurality of beams in a respective layer at points of incidence of the plurality of beams on the material that can be solidified, wherein the points of incidence of the beams for solidifying selective regions of the layers of the material that can be solidified in order to manufacture the three-dimensional workpiece are each controlled substantially against a gas flow direction of a gas flow over the surface of the carrier; wherein the control method comprises (a) dividing the material to be solidified in the respective layer into at least two sections, wherein two of the at least two sections extend in the gas flow direction of the gas flow prevailing over the two of the at least two sections in succession at least in part, (b) dividing at least one of the two of the at least two sections into at least two surface pieces, (c) assigning each of the surface pieces to exactly one specific beam, which solidifies the material to be solidified in the assigned surface piece, (d) controlling the points of incidence of the beams such that, at at least one point in time during an exposure of the material to be solidified, the material to be solidified is solidified in at least two surface pieces, and a network consisting of straight lines extending between each center point of the points of incidence to every other center point of the points of incidence, at no point in time during the exposure, in which all center points of the points of incidence are located outside of a predetermined distance from each other, has a straight line parallel to the gas flow direction of the gas flow prevailing over the two of the at least two sections.
