Beschreibung
Zusammenfassung:	An unpacking system (26) for use in an apparatus (10) for producing three-dimensional work pieces by irradiating layers of a raw material powder with electromagnetic or particle radiation comprises a supporting structure (28) which is configured to support a building chamber arrangement (25). The building chamber arrangement (25) comprises a building chamber (18) accommodating a carrier (16), the carrier (16) being configured to receive a three-dimensional work piece (11) produced from a raw material powder by an additive layering process. A lowering mechanism (30) of the unpacking system (26) is configured to apply a driving force to the building chamber (18) so as to lower the building chamber (18) relative to the carrier (16) until a three-dimensional work piece (11) received on the carrier (16) can be removed from the carrier (16).
