<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a three-dimensional molded article, which allows efficient manufacture of a three-dimensional molded article including information that can be read out if necessary but under normal conditions, that cannot be identified.SOLUTION: The method for manufacturing a three-dimensional molded article aims to manufacture a three-dimensional molded article by carrying out a plurality of times of layer formation steps where layers are formed by using a composition, so as to stack the layers. A substantial part of the three-dimensional molded article is formed by depositing a plurality of inks to a region to constitute the three-dimensional molded article, in which a virtual image formation pattern is formed by using at least one ink for forming a virtual image as the above ink. The virtual image formation pattern gives information to an observer when the three-dimensional molded article is observed by use of a lens assembly including a plurality of lenses, while the information cannot be observed by direct observation of the three-dimensional molded article.</p> |
