<jats:p>The forging rapid prototyping we proposed based on CAD data involves numerically controlled free forging and metal hammer working as new three-dimensional modeling. Almost all products are now designed and developed using CAD/CAM, and rapid prototyping using CAD data is also used to model design previews or mock ups. Free forging and plastic working, however, have few ways to automate the process. We developed numerical controlled free forging and metal hammer working as new modeling for rapid prototyping. Experimental results demonstrate that our proposal provides feasible three-dimensional modeling as rapid prototyping.</jats:p>
