Embodiment Construction

[0057] figure 1 Illustrated according to an exemplary embodiment for layer-by-layer selective irradiation and subsequent curing of layers of powdered construction material 3 curable by means of at least one energy beam 4 , for example metal powder A schematic diagram of an exemplary embodiment of a device 1 for the additive manufacturing of three-dimensional objects 2 , for example technical structural parts. The energy beam 4 can be, for example, an electron beam or a laser beam. The device 1 can thus be embodied as, for example, a selective electron beam melting device or a selective laser melting device.

[0058] The device 1 comprises a plurality of functional and / or structural units operable during and during its operation. Each functional and / or structural unit may comprise a plurality of functional and / or structural subunits. The functional and / or structural units and the operation of the device 1 are respectively controlled by a (central) control unit 5 .

Abstract

The invention provides a method for additively manufacturing at least one three-dimensional object by means of successive layerwise selective irradiation and consolidation of layers of build material applied in a build plane of an apparatus for additively manufacturing three-dimensional objects by means of at least one energy beam, whereby the process gas stream is adapted to transport respective fume particles from a layer of build material which are generated during selective irradiation and consolidation of the respective layer of build material; wherein for at least one layer of build material which comprises a first area which is to be irradiated and consolidated and at least one further area which is to be irradiated and consolidated, it is determined that the process gas stream being chargeable or charged with fume particles generatable or generated during irradiation and consolidation of at least one of the areas which are to be irradiated and consolidated fulfils a pre-definable or pre-defined scheduling criterion; wherein the start time for starting irradiating and consolidating of the first area and/or the start time for starting irradiating and consolidating the at least one further area is determined on the basis of the determination that the process gas stream has fulfilled the pre-definable or pre-defined scheduling criterion.

Description

technical field [0001] The invention relates to a method for additively manufacturing at least Method for a three-dimensional object in which a process gas flow is capable of entraining soot particles generated during selective irradiation and curing of corresponding layers of build material while flowing over a build plane, wherein the process gas flow is adapted to flow from a build material The corresponding particles generated during the selective irradiation and curing of the corresponding layer of construction material are removed or transported away from the layer of the building material. Background technique [0002] For example, corresponding methods for additively producing at least one three-dimensional object which can be implemented as a selective electron beam melting process or a selective laser melting process are generally known from the technical field of additive manufacturing. [0003] It is thus known that the process gas stream can entrain, while flow...
