20150159007 | MOLD MATERIAL, MOLDING METHOD, MOLD OBJECT, AND MOLDING APPARATUS - A molding apparatus includes a heating section, a spreading section, a molding section, a drawing section and a curing section. The heating section which heats a mold material including particles and a binder agent which bonds together the particles, to a temperature equal to or higher than the melting point of the binder agent and forms a fluid mold material. The spreading section forms a mold layer by spreading the fluid mold material. The molding section layers the mold layers. The drawing section applies UV ink to a desired region of the mold layer. The curing section cures the UV ink applied to the desired region of the mold layer. | 06-11-2015 |
