Abstract
Method for operating an apparatus (1) for additively manufacturing three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy source, wherein irradiation data define at least two regions (8, 9) of object data relating to a three-dimensional object (2), which regions (8, 9) are irradiated based on at least two different irradiation parameters.

A method for operating an apparatus for additively manufacturing three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material, the method comprising:
- consolidating the layers of the build material by means of an energy source,
- wherein an irradiation data defines at least two regions of object data relating to a three-dimensional object,
- which wherein the at least two regions are irradiated based on at least two different irradiation parameters,
- assigning at least one first irradiation parameter to an at least one first region and at least one second irradiation parameter to an at least one second region based on a geometry information of the first region and the second region and/or
- irradiating the at least one first region based on at least one first irradiation parameter and the at least one second region based on at least one second irradiation parameter based on a geometry information of the at least one first region and the at least one second region;
- generating intermediate object data based on the object data relating to a geometry of the three-dimensional object,
- wherein at least one part of a contour of the three-dimensional object that is defined by an original object data of the three-dimensional object is decreased by a threshold value and structures of the three-dimensional object that are defined by the original object data comprising a corresponding dimension below the threshold value are removed and the at least one part of the contour is increased to an initial value.
An apparatus for additively manufacturing three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material, the apparatus comprising:
- an energy source,
- a control unit connected or connectable to the apparatus, that is adapted to generate or receive an irradiation data,
- wherein the irradiation data define at least two regions of object data relating to a three-dimensional object,
- wherein the control unit is configured to cause the apparatus to irradiate the at least two regions based on at least two different irradiation parameters,
- wherein the control unit assigns at least one first irradiation parameter to an at least one first region of the object data and assigns at least one second irradiation parameter to an at least one second region of the object data based on geometry information of the first region and the second region and/or controls irradiating the at least one first region based on at least one first irradiation parameter and controls irradiating at least one second region based on at least one second irradiation parameter based on a geometry information of the first region and the second region;
- wherein the control unit is adapted to generate intermediate object data based on an original object data relating to a geometry of the three-dimensional object, wherein the control unit is adapted to decrease at least one part of a contour of the three-dimensional object that is defined by the original object data of the three-dimensional object by a threshold value and remove structures of the three-dimensional object that are defined by the original object data comprising a corresponding dimension below the threshold value and increase the at least one part of the contour to an initial value.
