Abstract: The present invention provides a three-dimensional model that contains an olefin-based polymer and can be easily processed, and a three-dimensional modeling material for obtaining the same. In addition, an object of the present invention is to provide a three-dimensional modeling material that contains an olefin-based polymer and can impart a function to a three-dimensional model itself. Furthermore, another object of the present invention is to provide a three-dimensional model production method using a three-dimensional modeling material. A three-dimensional modeling material that solves the above problems is a material for forming a three-dimensional model using thermal energy and contains an olefin-based polymer and an organometallic complex. The organometallic complex contains a central metal, a ligand coordinated to the central metal, and a compatible group having a structure in which four or more carbon atoms bonded to the ligand are linearly arranged, and the central metal has one or more vacant orbitals.

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. The reconstructed image is created while the inspection object H is placed on the subject table 13 in such a way that at least the lamination direction of layers constituting the inspection object H and the arrangement direction of the plurality of slits S in the plurality of grids are parallel. The inner state of the inspection object H is inspected on the basis of the reconstructed image.
