  • Photo-curable resin composition for three-dimensional molding, method for three-dimensional molding using the same, and three-dimensional molded product
    Patent number: 11491709
    Abstract: A photo-curable resin composition for three-dimensional molding which does not require a support material is provided and can be cured by light irradiation while being extruded from a nozzle through a simple FDM method to be stacked and molded in a short period of time. The photo-curable resin composition has a viscosity at 20° C. of 0.2 Pa·s or more and a viscosity at 150° C. of 1000 Pa·s or less.
    Type: Grant
    Filed: June 24, 2019
    Date of Patent: November 8, 2022
    Assignee: KJ CHEMICALS CORPORATION
    Inventors: Yoshio Kunihiro, Yuya Ishimaru, Toshitsugu Kiyosada
  • Three-dimensional molding apparatus and three-dimensional molding method using different types of materials
    Patent number: 11478982
    Abstract: A three-dimensional molding apparatus is provided and includes a reservoir portion, a nozzle portion, a liquid-sending unit, and a temperature control unit that correspond to each of the two or more different types of materials, a molding stage, a relative movement mechanism for moving the stage and the nozzle portions, and a control computer. By using this apparatus, industrial additive manufacturing with two or more different types of materials can be realized with high precision, and high-definition molded products in which different types of materials are arbitrarily combined can be produced.
