Abstract: The invention relates to a 3D printer having an advantageous irradiation device, and a method for 3D printing. The irradiation device is an array of multiple irradiation units each of which is individually controllable with regard to its temperature. According to an embodiment, a subset of irradiation units is combined to a group, each group of irradiation units being controllable with regard to its temperature. The target temperature of the irradiation units at the edges can be set to a temperature that is higher than the target temperature of the irradiation units in the remaining area.

Abstract: The invention relates to an arrangement for the layer-by-layer formation of mouldings from a particulate material, comprising at least one process unit which can be guided to and installed in the arrangement, preferably automatically, and which comprises a printing unit and a coating system with a dynamic filling system; or/and a receiving device for a building container; a preferably automatic feeder for the building container; and an adjustment device for offline preparation of the process unit.

Abstract: The invention relates to a method and an apparatus for producing three-dimensional models by layering technology, and a recoater with a vacuum closure.
