  • Publication number: 20210109038
    Abstract: Provided is a quality inspection method in which an inner state of a three-dimensional laminated molding can be quickly and easily inspected without destroying the three-dimensional laminated molding. To this end, the quality inspection method uses an X-ray Talbot imaging system 1 which creates a reconstructed image of an inspection object on the basis of a moire image obtained by using an X-ray detector to read X-rays which, after being radiated from an X-ray source 11a, have passed through: a plurality of grids in which a plurality of slits S are arranged in a direction perpendicular to the radiation axis direction of the X-ray; and an inspection object H placed on a subject table 13. The inspection object H is a three-dimensional laminated molding formed into a three-dimensional shape by laminating multiple layers of constituent materials.
