Problems solved by technology

[0004] Said test irradiation is time and effort consuming and furthermore cannot be carried out during the additive manufacturing process, since test samples, for example metal sheets, have to be inserted into the process chamber and thereafter removed to analyze the irradiated pattern

Embodiment Construction

[0042] figure 1 A device for the additive production of a three-dimensional object 2 is shown by selectively irradiating and curing layers of a building material 3 which can be cured by means of an energy beam 5 guided into the interior of a process chamber 6 of the device 1 by selectively irradiating and curing them layer by layer in succession 1. The device 1 comprises determining means 7 , 8 adapted to determine at least one parameter of the energy beam 5 . Thus, an energy beam 5 can be generated and guided via the irradiation device 32 , in particular in such a way that the energy beam 5 is incident on the determination device 7 , 8 . The energy beam 5 incident on the respective determination device 7 , 8 is shown via dashed lines to emphasize that the energy beam 5 can be directed to the respective determination device 7 , 8 . as from figure 1 It follows that the determining devices 7 , 8 are arranged inside the process chamber 6 .

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 that is guided inside a process chamber of the apparatus, wherein a determination device is provided that is arranged inside the process chamber and adapted to determine at least one parameter of the energy beam, preferably during an additive manufacturing process, in particular during a process step of the additive manufacturing process in which build material is applied onto a build plane of the apparatus. Further, the invention relates to a method for operating at least one 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.

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 a construction material which can be cured by means of an energy beam guided into the interior of a process chamber of the device. Background technique [0002] Devices are generally known from the prior art for the additive manufacturing of three-dimensional objects by selectively irradiating build materials layer by layer. Such devices use, for example, energy beams to selectively irradiate a layer consisting of a build material that is cured due to energy consumption due to irradiation with the energy beam. In order to achieve a defined object quality and process quality, it is also known that parameters of the energy beam, for example optical parameters, must be monitored. [0003] Typically, the parameters of the energy beam are monitored using a determining device, such as a camer...
