Embodiment Construction

[0035] figure 1 Shown is a device 1 for the additive manufacturing of a three-dimensional object 2 by means of sequential layered selective irradiation and consolidation of layers of building material 3 which can be consolidated by means of an energy source. The apparatus 1 further comprises an illumination device 4 adapted to selectively illuminate the build material 3 arranged in the build plane 5 . The build material 3 is applied via an application unit 6 comprising a dosage unit 7 and an application element 8, as will be referred to later image 3 as described.

[0036] In other words, the application unit 6 is adapted to apply the building material 3 on the carrier element 9 (or a previously applied layer of the building material 3 carried by the carrier element 9), wherein, in particular, the application unit 6 is adapted to apply the arc-shaped Build material layers. exist Figure 1 to Figure 3 In the exemplary embodiment depicted in , the carrier element 9 is disc-...

Abstract

A device for additively manufacturing a three-dimensional object (2) by selectively irradiating and solidifying a layer of building material (3) in successive layers, the layer of building material (3) being consolidated by means of an energy source, the device (1) comprising applying A unit (6) for applying the building material (3) on at least one carrier element (9) carrying the building material (3) applied to the carrier element (9), an irradiation device (4) at least partially consolidating at least a portion of at least one wall element (20, 21), and / or providing a wall building unit (17) that builds at least one wall element ( 20, 21), a first wall construction element (18) and a second wall construction element (19) are provided, the first wall construction element (18) and the second wall construction element (19) are arranged at least partially on the carrier element (9 ) next to the volume of build material (22) carried, in particular, in the form of a portal.

Description

technical field [0001] The invention relates to a device for the additive manufacturing of three-dimensional objects by means of sequential layer-by-layer selective irradiation and consolidation of layers of building material which can be consolidated by means of an energy source, wherein the device comprises an application unit, The application unit is adapted to apply the build material on at least one carrier element, the at least one carrier element being adapted to carry the build material applied to the carrier element. Background technique [0002] Devices for the additive manufacturing of three-dimensional objects by selectively irradiating and solidifying layers of building material in successive layers are generally known from the prior art, for example selective laser melting devices or selective laser sintering devices. Typically, build materials are applied in layers and selectively irradiated to form corresponding layers of the object to be additively built. T...
