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,

Device and method for a layerwise manufacturing of a 3-dimensional object from a building material in powder form

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 thatthe building material in powder form is mechanically consolidated when a layer is applied.

Device and method for a layerwise manufacturing of a three-dimensional object from a building material in powder form

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 comprises 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. The applicator () has a receiving device () for receiving a applying module such as a blade module (). The receiving device () is formed in a way so that the applying module () 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.

Apparatus for manufacturing a three-dimensional object layer by layer

A process is provided for producing a three-dimensional object having the steps forming the object () in a container () arranged within a process chamber () on a carrier () which can be displaced in the container by sequential selective solidification of layers of a pulverulent material () which can be solidified by the action of electromagnetic or particle radiation at positions corresponding to the cross-section of the object in the particular layer, characterized by the step of controlled removal of non-solidified pulverulent material () after completing the object ().
