Embodiment Construction

[0038] figure 1 Is shown according to an exemplary embodiment for the layer-by-layer selective irradiation and subsequent curing of a powdered building material 3 (eg metal powder) curable by means of at least one energy beam 4 (eg laser beam) A schematic diagram of an exemplary embodiment of a device 1 for additively manufacturing a three-dimensional object 2 (for example a technical structural part) from layer to layer. The device 1 may be, for example, a selective laser melting device.

[0039] The device 1 comprises a support structure 5 . The support structure 5 is configured to support the functional units 6 - 8 of the device 1 . The support structure 1 may comprise a plurality of interconnected structural elements 5a-5c, such as strut elements, arranged in a frame-like, rail-like or scaffold-like spatial arrangement. The arrangement of the structural elements 5a-5c defines an inner space or volume 5d of the support structure 5 in which the respective functional unit ...

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 beam (4). The apparatus (1) comprises: a support construction (5); and at least one functional unit (6-10) of the apparatus (1), supported by the support construction (5),wherein the at least one functional unit (6-10) is moveably supported relative to the support construction (5), whereby the at least one functional unit (6-10) is moveably supported between an operating position in which the at least one functional unit (6-10) is positioned inside the support construction (5) and a service position in which the at least one functional unit (6-10) is at least partially positioned outside the support construction (5).

Description

technical field [0001] The invention relates to a device for the additive manufacture of three-dimensional objects by selectively irradiating and curing layers of building materials curable by means of energy beams sequentially layer by layer, the device comprising a support structure and a At least one functional unit. Background technique [0002] Devices for the additive production of three-dimensional objects are generally known. Exemplary embodiments of corresponding devices are selective laser sintering devices, selective laser melting devices and selective electron beam melting devices. Furthermore, metal bond jetting devices can also be considered as corresponding devices. [0003] The respective device generally comprises a support structure supporting a plurality of functional units of the respective device. The support structure can be embodied as a support frame with a plurality of support interfaces at which functional units of the device, for example process...
