Problems solved by technology

[0003] Consequently, build-up material particles transported by gas flow or by contact transfer may contaminate areas of the process chamber that should be kept free of build-up material
The undesired deposition of stirred build material in the process chamber may disturb or impair the manufacturing process, especially the continuous operation of the manufacturing process, since the various areas where build material is not desired must be cleaned or maintained

Embodiment Construction

[0029] figure 1 A device 1 is shown for the additive production of three-dimensional objects by selectively irradiating and curing layers of a powdery construction material 2 curable by means of energy beams sequentially layer by layer. The device 1 comprises a process chamber 3 having at least a first area 4 and a second area 5 .

[0030] The first region 4 comprises a build plane 6 in which the build material 2 is irradiated with the energy beam. In other words, in the first zone 4, the building material 2 is supplied by the metering module 7, wherein the building material 2 is applied to the building plane 6 via the cladding device 8, wherein the excess building material 2 is collected in the overflow module 9 . From figure 1 , figure 2 It can further be drawn that the cladding device 8 can be selectively moved from the second zone 5 into the first zone 4, wherein figure 1 shows the applicator 8 in a position in the second area 5, figure 2 The cladding device 8 is s...

Abstract

Apparatus (1) for additively manufacturing of three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material (2) which can be consolidated by means of an energy beam, with a process chamber (3) comprising at least a first and a second region (4, 5), wherein in the first region (4) build material (2) is applied and irradiated on a build plane (6), wherein a stream generating unit is provided that is configured to generate a stream of process gas (10) in the process chamber (3) separating the first region (4) from the second region (5).

Description

technical field [0001] The invention relates to a device for the additive production of three-dimensional objects by sequentially layer-by-layer selective irradiation and curing of layers of building materials curable by means of energy beams, wherein the process chamber comprises at least a first region and a second zones, wherein in the first zone the build material is applied and irradiated on the build plane. Background technique [0002] Devices are known from the prior art in which an energy beam is generated to selectively irradiate layers of build material. The build material is cured by irradiation, wherein an object may be built by successively irradiating and curing layers of build material to form the object. The building material, usually in powder form, is distributed and / or carried throughout the process chamber of the plant, since the building material is for example partly evaporated or stirred during the manufacturing process. [0003] Consequently, build...
