  • Figure-forming composition, method for forming three-dimensional figures and three-dimensional structures by using the same
    Patent number: 8105517
    Abstract: It is an object of the present invention to provide a figure-forming composition which enables the initiation of hardening even with a small amount of water and can attain a prescribed hardness, and which is suitable particularly for the production of three-dimensional living body models for surgical training by a rapid prototype process; and provide a three dimensional figure and a three-dimensional structure which are formed by using the composition. The figure-forming composition, for example, comprises a calcium-based material such as hemihydrate gypsum and polyvinyl alcohol resin, wherein the content of the polyvinyl alcohol resin is 2 to 20 weight parts when the total weight of the calcium-based material and the polyvinyl alcohol resin is 100 weight parts.
    Type: Grant
    Filed: April 10, 2007
    Date of Patent: January 31, 2012
    Assignee: Next21 K.K.
    Inventors: Shigeki Suzuki, Koutaro Shimizu, Shinya Wasada, Hironobu Okamoto, Shinro Takai
