Virtual design and fabrication in layered manufacturing

A web-based, user friendly virtual design and fabrication system has been developed. It informs new users of basic rapid prototyping concepts and techniques, and provides a linked dictionary for unfamiliar terminology. Important details are given on the quickly emerging field of rapid tooling. Beyond this preliminary information, Java applets provide an interactive element to allow the user to make informed decisions regarding machines and materials. Several tutorials guide the user through the process, from initial design through selection of build parameters. In many cases, there exists a need for a smooth transition from CAD design to complex rapid prototyping techniques. This knowledge base should reduce the iterations required to successfully build parts via stereolithography or fused deposition modeling.
