摘要： The invention relates to a device (10, 100, 150, 200, 250, 300), in particular for the layer-by-layer additive production of a complex three-dimensional component (12), comprising a measuring device (30, 202, 252, 302) for continuously monitoring quality parameters, in particular the temperature and/or a chemical composition of a protective gas atmosphere (24), during the production of the component (12). The measuring device (30, 202, 252, 302) and a bed (14) with a material powder (16) are surrounded at least in some regions by a processing cell (22) filled with a protective gas atmosphere (24), and the material powder (16) of an uppermost layer (18) can be melted in a spatially restricted manner in a melting zone (42) by means of at least one laser (32, 204, 254, 304). According to the invention, the measuring device (30, 202, 252, 302) has the at least one laser (32, 204, 254, 314) and at least one optical sensor (34, 206, 218, 256, 306, 308) for detecting the quality parameters in the region of the melting zone (42) in advance, in particular by means of Raman spectroscopy. As a result, possible construction faults in the component (12) can be immediately detected, evaluated, and optionally corrected in a resource-saving manner.
