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

Abstract: A method for producing 3D moulded parts, wherein one or more building materials in the form of particles are applied in a defined layer to a building area by means of a coater (101), one or more absorbers or one or more liquids comprising one or more absorbers are selectively applied as printed image dots by means of a printhead (100), an energy input is performed by means of an energy source (108, 109), wherein the regions with selectively applied absorber are selectively solidified, the building area is lowered by the thickness of a layer or the coater is raised by the thickness of a layer, these steps are repeated until the desired 3D moulded part (103) is created, wherein the amount of absorber within a layer (301) per printed image dot is set to a predetermined value and wherein predetermined values that are different in two or more image dots can be set within a layer.
