THREE-DIMENSIONAL SHAPED ARTICLE PRODUCTION METHOD AND THREE-DIMENSIONAL SHAPED ARTICLE

摘要

A three-dimensional object is provided that achieves adequate hardness while suppressing volume shrinkage. Used as an ink that forms a modeling material are at least two types of photo-curing inks curable by being irradiated with light and having degrees of hardness that mutually differ in eight hours after being irradiated with light. The at least two types of photo-curing inks are discharged in a manner that dots of these photo-curing inks are mixedly present.
