METHOD FOR ADDITIVELY MANUFACTURING THREE-DIMENSIONAL COMPONENTS AND CORRESPONDING DEVICE

The invention relates to a method for additively manufacturing three-dimensional components by layer-by-layer application of a build-up material and locally selective solidification of the build-up material by at least one beam (15) impinging on the build-up material and following a feed direction (...

Zusammenfassung:The invention relates to a method for additively manufacturing three-dimensional components by layer-by-layer application of a build-up material and locally selective solidification of the build-up material by at least one beam (15) impinging on the build-up material and following a feed direction (12), wherein an irradiation path (10) of the impinging beam deviates during the feed from a, in particular straight, feed centre line M, wherein at least one line P parallel to M or corresponding to M is successively crossed by the irradiation path (10) at three points P1, P2 and P3, so that applies: P2 lies further forward in the feed direction than P1 and P3 lies between P1 and P2, at a distance p1 from P1 and a distance p2 from P2, where: p2/p1≥2.0, preferably p2/p1≥3.5.
