Abstract: The present invention relates to a method for producing three-dimensional objects based on computer data by repeated application in layers of a medium containing particulate material and selective solidification of the medium, whereby a feedstock made of medium in a build space is provided and a layer application of the medium takes place on a surface of the feedstock bordering the build space at an angle β and a solidification according to computer data occurs by use of a solidification unit, characterized in that the feedstock is not moved during build-up of the object.

Abstract: The present invention relates to a multi-stage method for producing one or multiple molded bodies, the method comprising the following steps: a) constructing one or multiple molded bodies in layers by repeatedly applying particulate material by the 3D printing method; b. a presolidification step for achieving a presolidification of the molded body; c. an unpacking step, wherein the unsolidified particulate material is separated from the presolidified molded body; d. a final solidification step, in which the molded body receives its final strength due to the action of thermal energy. The invention also relates to a device which may be used for this method.
