| titleOfInvention | Calculating exposure paths having low component distortion |
| abstract | A computer-assisted method for providing control data for an additive manufacturing device (1) for manufacturing a three-dimensional object (2) by means of said device, wherein the object (2) is manufactured by applying a build-up material (15) layer-by-layer and solidifying the build-up material (15) by feeding radiation energy to points in a layer that are associated with the cross section of the object (2) in this said by scanning said points with at least one energy beam bundle (22) in accordance with a set of energy input parameters along a number of solidification paths (30, 31) in a construction plane by means of at least one energy-inputting means (20) for inputting energy into the build-up material (15). The method for providing control data comprises: a first step (S1) of accessing computer-based model data from two cross sections of an object portion which are to be solidified and which are chronologically successive, preferably directly chronologically successive, in the manufacturing process; a second step (S2) of producing a data model of each of the two cross sections, wherein a scanning of the build-up material layer with at least one energy beam bundle (22) along at least one solidification path (30, 31) is specified in the data model for each of the two cross sections, wherein it is specified that, when the points of a build-up material layer which are associated with a cross section to be solidified are scanned, the region of contact of at least one energy beam bundle (22) with the build-up material is moved along at least one portion of a distortion field isoline, wherein a portion of a distortion field isoline along which the contact region is moved when the cross section that is to be solidified at a later time is scanned is selected such that it has a different position and/or orientation in the construction plane with respect to a portion of a distortion field isoline along which the contact region is moved when the cross section that is to be solidified first is scanned; and a third step (S3), in which control data corresponding to the data model produced in the second step (S2) are provided for the generation of a control data set for the additive manufacturing device (1). |
