  • Method and fabricating tools for earth boring
    Publication number: 20030094730
    Abstract: A method for creating a rapid prototype mold for parts of an earth boring tool for manufacture thereof comprises initially optimizing the drill bit design and integrating this design into CAD code. The CAD code is utilized to generate a prototype file in a computer outputting command signals to a laser, and a laser scanner to prototype a mold utilizing stereolithography, selective laser sintering, or laminated object manufacturing, in addition to other prototype techniques to manufacture earth boring tool parts.
