The aim of this presentation is to illustrate the application of X-ray computed tomography (CT) not only for non-destructive inspection but also for the metrological assessment of diverse manufactured parts, particularly by using dimensional metrology (part-to-CAD comparison, wall thickness analysis, size measurements) and for material inspection (voids and defect detection). The benefits of CT for the quality assessment and inspection of new manufacturing technologies such as additive manufacturing (or 3D Printing) will be considered.
