Abstract: The present invention relates to materials for a multi-stage method for producing one or multiple molded bodies. The materials may be used in a method including constructing one or multiple molded bodies in layers by repeatedly applying particulate material by the 3D printing method; pre-solidifying the molded body; unpacking the pre-solidified molded body and removing unsolidified particulate material, and final solidification of the molded body for achieving a final strength due to the action of thermal energy. The invention also relates to a device which may be used for this method.

Abstract: A process and an apparatus for producing 3D moldings, wherein a spectrum converter is used. Said converter is defined as a means which absorbs a radiation, for example electromagnetic thermal radiation, and radiates or emits one or more defined wavelength ranges; the spectrum converter is here irradiated by an emitter of an electromagnetic thermal radiation (shortwave or longwave radiation), i.e. by a lamp or an emitter, for example an overhead emitter or a sintering unit, and then emits a defined electromagnetic thermal radiation.
