Abstract

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.
