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...

Abstract

Apparatus (1) for additively manufacturing three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy source, wherein an irradiation device (4) with at least one irradiation unit (5) is provided that comprises a common holding structure (6), in particular a common housing,holding at least two irradiation elements (7) in a defined spatial relation, wherein the at least two irradiation elements (7) are individually controllable.

Description

technical field [0001] The invention relates to a device for the additive production of three-dimensional objects by selectively irradiating and curing layers of a construction material curable by means of energy beams sequentially layer by layer. Background technique [0002] Apparatus are known in the prior art for the additive manufacturing (ie additive manufacturing) of three-dimensional objects, for example by selectively irradiating and curing layers with an energy source, for example an energy beam, such as a laser beam. Typically, an irradiation unit, such as a laser source, is provided, which is adapted to generate a corresponding energy beam. The energy beam is directed onto a build material that can be arranged in a build plane. [0003] Furthermore, it is known in the prior art that various parameters of the energy beam during irradiation directly affect the curing properties of the build material. For example, the energy depleted within a given volume of build...
