  • Method for manufacturing fiber-reinforced parts utilizing stereolithography tooling
    Patent number: 6248504
    Abstract: A method of manufacturing a three-dimensional fiber-reinforced part utilizing the single-tool method of stereolithography. The tool is fabricated by designing the tool on a computer-aided design system and curing successive layers of a fluid medium via a computer-controlled irradiation source to form the three-dimensional tool. The desired part is generated by applying layers of resin-wetted fabric to the tool, curing the fabric on the tool, removing the tool from the designed part and cleaning, trimming and inspecting the designed part.
    Type: Grant

  • Flexible reinforced rubber part manufacturing process utilizing stereolithography tooling
    Patent number: 5603797
    Abstract: A single-tool manufacturing process utilizing a stereolithographic tool for fabricating flexible reinforced rubber parts. The stereolithographic tool is fabricated using a laser and computer-controlled optical scanning system. Then fabric and resin are manually applied to the tool. The stereolithographic tool is utilized like a mold, with successive layers of fabric and resin applied thereto. After curing, the mold is shattered and removed from the designed part.
