ABSTRACT:
A 3D modeling device performs repeatedly a step of cutting a subsidiary material layer formed of a subsidiary material and cutting a modeling material layer formed of a modeling material. The 3D modeling device comprises at least one of a subsidiary material supplying device which discharges the subsidiary material drop by drop from an outlet positioned apart from a region in which the subsidiary material is to be applied at a predetermined distance, and a modeling material supplying device which discharges the modeling material drop by drop from an output positioned apart from a region in which the modeling material is to be applied at a predetermined distance. Since the material can be applied with high precision, a high-quality 3D molded object is provided.
