Abstract: 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.
