摘要： An apparatus for the simultaneous layer-by-layer production of three-dimensional objects, containing a construction chamber with a height-adjustable construction platform, an apparatus for applying, to the construction platform, a layer of a material that can be hardened by exposure to electromagnetic radiation, and irradiation equipment. The irradiation equipment contains a radiation source emitting electromagnetic radiation, a control unit and a lens located in a beam path of the electromagnetic radiation, for irradiating sites within the layer that correspond to an object, in which a cooling element can be produced at the same time as the object. A process for the layer-by-layer production of a three-dimensional object in the apparatus, involves producing an object and a cooling element at the same time.
