Industrial computed tomography (CT) is an x-ray imaging technology ideal for internal inspection of complex 3D printed parts. As a non-destructive testing method (NDT) that provides non-contact inspection, CT is primed to meet the challenges of additive manufacturing. This presentation will discuss high-energy CT using a linear accelerator, which has yielded a significant reduction in inspection time for larger parts and cleaner imaging of internal components. This translates to savings in cost and time as well as improved quality management and part development for additive manufacturing. This presentation will also cover the types of analyses available with high-energy CT scanning. These include dimensional metrology for complex geometries and part-to-CAD/part-to-part comparisons as well as accurate data for failure analysis, assembly verification, and identification of defects like porosity and residual powders. CT data can also be useful for optimizing the additive manufacturing process, including validation of 3D printed test bars and pre-production inspection for First Article Inspection (FAI) reporting to satisfy PPAP and AS9102 requirements.
