Example Embodiment

[0038] figure 1 , 2 In each case a schematic diagram of a device 1 is shown for a powdery construction material 3 ( Three-dimensional objects 2, such as technical components, are additively manufactured from layers of metal powder, for example. The device 1 can be, for example, a selective laser melting device or a selective electron beam melting device.

[0039] The device 1 comprises a plurality of structural and / or functional units.

[0040] An exemplary functional unit is an irradiation device 5 , in particular an energy beam generating device and / or an energy beam deflecting device, such as a scanning device, for selectively irradiating the build material layer with at least one energy beam 4 .

[0041] A further exemplary functional unit is a build material application device 6 , in particular a coating device, for applying a layer of build material 3 onto the build plane 7 of eg the process chamber 8 of the device 1 .

[0042] Another exemplary functional unit is a ...

Abstract

The invention relates to an apparatus for additively manufacturing three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material which can be consolidated by means of an energy beam, the apparatus comprises: a process chamber comprising a build plane in which layers of build material are successively layerwise selectively irradiated and consolidated by means of an energy beam during operation of the apparatus; a gas stream generating device configured to generate a gas stream at least partly streaming through the process chamber during operation of the apparatus, the gas stream being capable of being charged with non-consolidated build material particles, particularly smoke or smoke residues generated during operation of the apparatus, while streaming through the process chamber; and an optical determining device configured to optically determine at least one parameter suitable for characterizing the streaming properties of the gas stream streaming through the process chamber during operation of the apparatus (1) at at least one defined location within the process chamber. The invention further relates to an opticaldetermining device for the apparatus.

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 building materials curable by means of energy beams sequentially layer by layer, the device comprising a process chamber, said process chamber comprising a build plane in which layers of build material are sequentially selectively irradiated and solidified layer by layer by means of an energy beam during operation of the apparatus; and a gas flow generating device configured to generate A gas flow that flows at least partially through the process chamber during plant operation, which can entrain uncured construction material particles, in particular fumes or smoke residues, generated during plant operation during flow through the process chamber. Background technique [0002] Devices for the additive production of three-dimensional objects are known and can be implemented, for example, in the form of selective laser...
