Additive Manufacturing (AM) techniques are quickly replacing conventional “subtractive” machining techniques for producing low-volume numbers of complex parts. While some of these parts may be used for safety-critical functions, the complex nature of these parts means they are less suited to conventional inspection techniques, for example, eddy currents or ultrasonics. X-ray micro-computed tomography (µCT) is the only technique that gives a full three-dimensional quantitative picture of the structure of a part, both internal and external, showing density variations, dimensional mismatches, voids and inclusions, and allows accurate measurements of these to be made. This presentation explains how µCT works and how the full 3D inspection of complex AM parts can give users confidence in this exciting new technology.
