Abstract:
1. A device for manufacturing a three-dimensional object by a layerwise solidification of a building material at positions in the respective layers that correspond to the object, which comprises: a machine frame; a building space provided in said machine frame; a building plane that is located in said building space; a supply opening for supplying building material to said building plane at the side of the building plane; a duct connected to said supply opening in order to supply building material to a said building space; and at least two filler pipes provided at the duct, which are independent from one another, wherein a connector for a building material supply container for the supply of building material from outside of the device is provided at each of the filler pipes, wherein each of the filler pipes is provided with a mechanism by which it can be moved between a first position in which the building material is supplied to the duct, and a second position in which the building material supply container is detachable from the connector and can be connected to the connector, and the filler pipes are designed such that one connector can be detached from the building material supply container, while building material is further supplied to the duct via the other connector and in the device a building process is on-going, and wherein operation of the device is not interrupted when the one connector is detached from the building material supply container.
