Abstract: A method is provided, by which a three-dimensional object is manufactured by a subsequent solidification of layers of a building material in powder form at the positions in the respective layer that corresponds to the cross-section of the object by means of the action of a laser or another energy source, wherein as building material in powder form a material is used which contains the old powder that has remained as unsolidified powder in the manufacturing of one or more previously formed objects and a proportion of new powder that has not been used before in any manufacturing process, characterized in that the building material in powder form is mechanically consolidated when a layer is applied.

Abstract: Apparatus for manufacturing a three-dimensional object (3) by solidifying a powdery constituent material layer by layer at the positions corresponding to the profile of the object (3) to be manufactured in the corresponding layer, by the action of a laser or another energy source comprises a support (2) on which the object (3) is formed and an applicator (6, 7) for applying a layer of the constituent material onto the support or a layer at least partially solidified in advance. The applicator (6, 7) has a receiving device (40) for receiving a applying module such as a blade module (30). The receiving device (40) is formed in a way so that the applying module (30) can be exchangeably inserted into and removed from the receiving device (40) in a way that a predetermined position of the applying module (30) in the receiving device (40) is reproducibly determined.
