Patent number: 10543530Abstract: 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.Type: GrantFiled: November 13, 2016Date of Patent: January 28, 2020Assignee: SLM Solutions Group AGInventors: André Hermann, Toni Adam Krol, Andreas Wiesner, Jan Wilkes, Bodo Haack, Karsten Huebinger, Peter Koerner, Simon Mueller, Kaj Merten Berggreen, Jonas Mersch
