Embodiment Construction
[0028] only figure 1 A device 1 is shown for the additive production of a three-dimensional object 2 by sequentially selectively irradiating and curing layers of a build material 3 curable by means of an energy beam 8 . The device 1 comprises an illumination device 4 with an illumination unit 5 comprising a common holding structure 6—in the exemplary embodiment, in the form of a common housing. The illuminating unit 5 also includes a plurality of illuminating elements 7 , five illuminating elements 7 being provided in this exemplary embodiment.
[0029] As can be seen from the figures, the illuminating elements 7 are arranged in a common holding structure 6 , in other words, wherein the common holding structure 6 encloses the illuminating elements 7 inter alia. Since the illuminating elements 7 are attached to the common holding structure 6 and to each other (optionally), the common holding structure 6 defines a spatial relationship and holds the illuminating elements 7 in th...
