Abstract

Additive manufacturing enables the production of complex geometries, both internally and externally. This poses a challenge to quality control. Non-destructive volumetric testing methods are required. Among these methods, X-ray computed tomography is currently the most promising. It enables not only to detect inner and outer defects but also to perform dimensional measurements. However, the method lacks of metrological tracability. To fill this gap, an EMPIR project 17IND08 AdvanCT involving several European countries was proposed. In this frame, DTU Mekanik and LNE have conducted a comparison campaign of XCT systems using machined material measures representative of additively manufactured parts. The purpose of the comparison was to investigate the performances of industrial X-ray computed tomography with respect to dimensional measurements on external but also on internal features.
