for Surgical Simulation and Treatment Planning  Applications

3D-DOCTOR exports 3D models to STL (both ASCII and Binary) for rapid prototyping machines, as well as DXF for AutoCAD, 3DS for 3DStudio, Wavefront OBJ, and VRML for viewing on the Internet by others. 

Once you have created 3D mesh models in 3D-DOCTOR, you can print them out using a 3D printer and a rapid prototyping machine. If you do not have access to a 3D printer, there are many service bureaus that can provide printing service.
