Abstract The cost of rapid prototyping (RP) can be justified if it overcomes human traits and behaviors. An RP model is generated by developing an accurate CAD database and transferring the file to CAM. The most notable benefit of RP is that it provides a physical model that is available in a few days. Some companies maintain that they have noted a 15-25 percent reduction in tooling cost when a toolmaker uses an RP model. XX
