Abstract:
1. Apparatus for manufacturing a three-dimensional object by solidifying a powdery constituent material layer by layer at the positions corresponding to the profile of the object to be manufactured in the corresponding layer, by the action of a laser or another energy source, comprising a support on which the object is formed, and an applicator for applying a layer of the constituent material onto the support or a layer at least partially solidified in advance and having a receiving device for receiving an applying module, wherein the receiving device is formed in a way so that an applying module selected from a plurality of differently pre-adjusted applying modules can be exchangeably inserted into and removed from the receiving device in a way that a predetermined position of the applying module in the receiving device is reproducibly determined, by a swiveling of the applying module in the receiving device, wherein the receiving device comprises: a supporting device allowing a swiveling movement of the applying module around a predetermined swiveling axis a stop for determining the predetermined position, and a return unit for urging the applying module by a swiveling movement around the predetermined swiveling axis until it abuts against the stop.
