METHOD AND DEVICE FOR THE GENERATIVE PRODUCTION OF A COMPONENT

摘要

The invention relates to a method for the generative production of a component (2) and to a device for carrying out such a method, having the following steps: applying a material layer with a constant layer thickness; solidifying a region of the material layer according to a component cross section; generating an eddy-current scan of the solidified region, a scan depth corresponding to a multiple of the layer thickness; determining a material characterization of the solidified region taking into consideration a previous eddy-current scan of solidified regions of lower-lying material layers; and repeating the steps until the component (2) is assembled. An electric material characterization of each individual layer is determined using a recursive algorithm of individual measurements (monolayer by monolayer), and thus the entire component is tested step by step completely in a highly resolved manner.

1. A method for the generative production of a component (2), comprising the steps of:
a) applying a material layer (36a, 36b, 36c) with a constant layer thickness; b) solidifying a region of the material layer (36a, 36b, 36c) according to a component cross section; c) producing an eddy-current scan of the solidified region, wherein a scanning depth (z) corresponds to a multiple of the layer thickness; d) determining a material characterization of the solidified region taking into consideration a preceding eddy-current scan of solidified regions of lower-lying material layers ((36a, 36b, 36c); e) repeating the steps a) to d) until the component (2) is assembled; and f) taking into consideration a weighting of the material layers (36a, 36b, 36c), which decreases with depth, in a comparison of the eddy-current scans.
