Kimihiro Fujimoto has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Three-dimensional modeling apparatus, three-dimensional model body manufacturing method, and three-dimensional modeling data
    Patent number: 10549346
    Abstract: In a three-dimensional modeling apparatus, diffusion of fumes generated around the modeling stage accompanying irradiation with an energy beam can be efficiently prevented. Three-dimensional modeling is performed by repeating scanning a modeling material arranged on a modeling stage with laser light to form a solidified layer. A cover is provided that locally surrounds an irradiation portion on the modeling material arranged on the modeling stage irradiated with the laser light, and suppresses diffusion of the fumes caused by irradiation with the laser light. In the cover, a stream of gas containing the fumes is regulated so as to cause the fumes to flow toward an upward portion inside the cover apart from the irradiated portion irradiated with the laser light.
