An interchangeable chamber is provided for a 3D printing device, wherein the interchangeable chamber includes a building space for receiving a building platform on which a three-dimensional object can be produced, which building space is designed to be temporarily open in the direction of a top of the interchangeable chamber, as well as optionally a storage container for storing building material and wherein the interchangeable chamber comprises a side wall and a cover, wherein the cover is adapted to close the interchangeable chamber at the top such that building material cannot get through the cover out of nor into the interchangeable chamber and the cover is coupled with the side wall.

Interchangeable chamber for a device and a method for generatively producing a three-dimensional object

A means for modifying a building space for a device for manufacturing a three-dimensional object by layerwise solidification of a powdery building material at the locations corresponding to the object in the respective layers comprises one or several small supports () or one or several building space partitioning elements () on a building platform (), thereby the device has one or several small building areas (), in which the powdery material may be efficiently used and different powder materials may be processed.
