Title: CHANGING CHAMBER FOR A DEVICE AND METHOD FOR THE ADDITIVE MANUFACTURING OF A THREE-DIMENSIONAL OBJECT
Abstract:
The invention relates to a changing chamber (4) for a device for producing a three-dimensional object by selectively solidifying construction material layer by layer at the cross-section of the object to be produced in locations corresponding to the particular layer, the changing chamber comprising a construction space (40) for accommodating a construction platform (41), on which the three-dimensional object (2) can be produced, which construction space is temporarily open toward a top side of the changing chamber, and optionally a reservoir (45) for storing construction material, and the changing chamber comprising a side wall (401) and a cover (400), the cover (400) being suitable for closing the changing chamber (4) at the top side in such a way that construction material (20) is substantially prevented from exiting or entering the changing chamber through the cover, and the cover being connected, in particular pivotably and/or slidably connected, to the side wall.
