Abstract: The invention relates to a method for the production of a three-dimensional moulded body (52) by successively solidifying layers of a powdery construction material (57), which can be solidified by means of electromagnetic radiation or partial radiation, on points corresponding to the respective cross section of the moulded body (52). A carrier (43), which receives the moulded body (52) after the moulded body (52) is produced in a construction chamber (42), is displaced from a working position into a cooling position (121), wherein at least the carrier (43) is cooled or is driven into a suction position (128), wherein the non-solidified construction material (57) is removed from the construction chamber (42) or is moved into a cooling and suction position, wherein the non-solidified construction material (57) is removed from the building chamber (42) and the carrier (43) is cooled.

Abstract: The invention relates to an apparatus and a process for producing a three-dimensional shaped body by successive consolidation of layers of a pulverulent build-up material, which can be consolidated by means of electromagnetic radiation or particle radiation, at locations corresponding to the respective cross section of the shaped body, having a beam source for generating a focussed beam and a deflection device for diverting the focussed beam onto the layer which is to be consolidated, having a carrier in a build-up chamber, adjacent to a process chamber, for receiving the shaped body which is to be formed, wherein at least two working stations are formed by in each case one process chamber, the process chambers are hermetically locked off and are each designed to be separate from one another, and the deflection device and the at least two working stations can be positioned in a working position with respect to one another.
