METHOD OF QUALITATIVE ANALYSIS OF LASER SELECTIVE FUSION POWDER LAYER

摘要

It is a method of qualitative analysis of the dust layer deposited in processes involving the deposition of dust layers, as in sls / slm, characterized by comprising a digital vision system (1), which is positioned to collect images. of the surface of the dust layer deposited by additive manufacturing machines for processing successive dust layers and, by having statistical distribution of the specific arrangement of that dust when deposited, and by comparing the blur or sharpness of the images obtained before fusion of the powder with pre-established patterns identify whether or not the deposited layer in that productive iteration exhibits deposition uniformity deviations, and is able to identify non-conformities in the layer and generate automatic layer repair action and alarm and is able to interrupt the process.
