A device ( 1 ) for manufacturing a three-dimensional object by a layerwise solidification of a building material at positions in the respective layers corresponding to the object is provided. The device comprises a machine frame ( 2, 3, 4, 5 ) and a building space ( 10 ) located in said machine frame, wherein in the building space ( 10 ) there are arranged: an application device ( 27 ) that applies layers of the building material onto a support device ( 26 ) and a previously solidified layer, respectively, by means of an application element ( 61 ); a dosage device ( 28, 29 ) that supplies building material from a building material accommodation region ( 23, 24 ) to the application device ( 27 ) for an application; and a heating device ( 31 ) for heating the applied layers of the building material. The building material accommodation region ( 23, 24 ) is limited by a wall that has a double-wall structure, so that a hollow space ( 34, 35 ) is formed therein.
