Quality assessment of the internal structure of additively manufactured aluminum parts by means of industrial computed tomography scanning
This work endeavors to devise a robust approach to evaluate the accuracy of volumetric features of additive manufacturing internal defects by means of computed tomography. For that purpose the use of a reference object is proposed. The proposed artefact is a volumetric assembly with plates (with defects) that can be disassembled and calibrated by a traceable measuring system. All components were made of aluminum alloy, a material with wide applications in aeronautics, automotive and medical fields. In addition, further investigations were carried out on the influence of the cumulative thickness of scanned material on the internal defect CT measurement accuracy. For each defect a novel procedure for porosity inspection is provided, including volumetric information such as shape, size, distribution, and volume, along with the corresponding task-specific uncertainty estimation.
