  • Three-dimensional molding producing method, three-dimensional molding producing apparatus, three-dimensional molding, and molding material
    Patent number: 10556380
    Abstract: A three-dimensional molding producing apparatus (100) includes: a three-dimensional molding forming device (130) that forms a three-dimensional molding (300) by a powder lamination method by using a molding material (200) obtained by mixing a urethane resin powder with a gypsum powder and; and a urethane resin impregnating device (150) that impregnates a urethane resin into the three-dimensional molding (300). The three-dimensional molding producing apparatus (100) further includes: an aqueous medium dipping device (170) for immersing the three-dimensional molding (300) in an aqueous medium after impregnation of the urethane resin by the urethane resin impregnating device (150) is completed. This makes it possible to form a high-strength three-dimensional molding in forming a three-dimensional molding by the powder lamination method. Furthermore, it is also possible to form a soft three-dimensional molding.
