In this example a typical 3D X-ray analysis is presented of some radio-controlled airplane engine parts. Thanks to Clinton from Micton Hobbies in Somerset West, for loaning us the parts. Here are photos of the parts:
The engine casing is a light metal casting, containing pores/defects. The 3D images clearly show all the defects down to 0.1 mm diameter, while sorting the defects to only show those bigger than 1 mm simplifies things for easy viewing of problem areas. The 2D slice image videos shows the defects in more detail (black spots in the slice image video).

The rotor assembly results are shown below. No porosity is found at all, indicating the part is not a casting. Angular deviation of the central rod can indicate possible problems. In this example, different materials are coloured in differently, and two metal inserts for balancing the blades are highlighted as well (their positions where not known before).
