METHOD FOR MANUFACTURING THREE-DIMENSIONAL MOLDINGS, APPARATUS FOR MANUFACTURING THREE-DIMENSIONAL MOLDINGS, THREE-DIMENSIONAL MOLDING, AND MOLDING MATERIAL

摘要

An apparatus (100) for manufacturing three-dimensional moldings is provided with: a three-dimensional molding-forming device (130) for forming a three-dimensional molding (300) by powder lamination using a molding material (200) in which a urethane resin powder has been mixed into gypsum powder; and a urethane resin-impregnating device (150) for impregnating urethane resin into the three-dimensional molding (300). The apparatus (100) for manufacturing three-dimensional moldings also is provided with an aqueous medium-soaking device (170) in which, after completing impregnation of urethane resin by the urethane resin-impregnating device (150), the three-dimensional molding (300) is soaked in an aqueous medium. As a result, in forming a three-dimensional molding by powder lamination, it is possible to form a high strength three-dimensional molding. It is also possible to form a soft three-dimensional molding.
