Abstract

The invention relates to a method and a device for the analysis of energy beams in systems for the additive manufacture of components (70) by means of layered solidification of a construction material (55) by an energy beam (30). The invention enables a determination of position-related beam data directly with respect to the processing point during the machining process. An additive manufacturing system includes a beam deflecting device (40), a processing plane (45), and a layer applicator (60). The device according to the invention comprises a movable beam barrier (17), a movable beam sampling module (20) and a measuring device (10) with a radiation detector (12).
