    摘要： The invention relates to a device (1) for producing three-dimensional workpieces (15), comprising a carrier (7) for receiving raw material powder (9), a build chamber wall (11, 11a, 11b) which extend substantially vertically and which is adapted to laterally delimit and support the raw material powder (9) applied to the carrier (7); an irradiation unit (17) for selectively irradiating the raw material powder (9) applied to the carrier (7) with electromagnetic radiation or particle radiation in order to produce on the carrier (7) a workpiece (15) manufactured from the raw material powder (9) by an additive layer building method, wherein the irradiation unit (17) comprises at least one optical element; and a vertical movement device (31) which is adapted to move the irradiation unit (17) vertically relative to the carrier (7). The build chamber wall (11, 11a, 11b) and the carrier (7) are adapted to be connected to one another in a stationary manner during the vertical movement of the irradiation unit (17) so that the vertical movement takes place relative to the carrier (7) and relative to the build chamber wall (11, 11a, 11b).

    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.
