A new computer-based rapid prototyping (RP) procedure known as stereolithography can aid physicians in planning surgery or prosthetic aids by generating 3D anatomical models. Computer models can be compiled from successive 2D computed tomoggraphy (CT) scans of the body part being treated. The 3D data sets generated from CT scans are then converted into a format appropriate for use in stereolithography equipment. A Belgian software firm, Materialise, developed the software necessary to produce the models. RP can be used to design implants and prosthetics accurate to within .0003 inches. Surgeons can also employ the plastic models to better visualize how a surgical procedure will be conducted with minimum damage to surrounding tissue. Medical instruments, probes and devices can also be developed with RP techniques.

It is difficult to describe digital prototyping. The technology was developed to eliminate the need for expensive physical prototypes of products and now encompasses the total design and development process. Some implementations include mechanical analysis and virtual reality technologies. Digital prototyping reduces the costs of product development through such capabilities as interference checking, analysis and testing performed prior to manufacture. Electronic prototypes are frequently superior to physical models, especially because they allow parts of the product to be tested and evaluated during the development process, instead of at the end of it. Computer-based simulations can demonstrate how the product will perform in various environments.
Conceptual design is driving demand for rapid prototyping (RP) technology. Earlier RP technologies are prohibitively expensive and take too long to produce a model that will be used for conceptual purposes. Concept modeling, or 3D printing, is a variation of RP designed for developing prototypes that will be used as visual aids. These models need to be inexpensive and quickly developed because most of them will only be looked at briefly and then thrown away. Concept modelers produce physical prototypes from a CAD model. The approaches employed vary from ink-jet modeling, which deposits a wax-like material to form the model, to the use of powder that is hardened with a binder. These models are not highly precise, although the ModelMaker II does provide a high level of precision.
Virtual reality and CAD systems usually model physical characteristics of products rather than behavioral. It does little good however, if you can reach the radio in your car, but can't use it. Behavioral simulations provide useful data to market researchers, human factors engineers and software engineers. Market researchers use simulations to find what product features are desirable to a focus groups. That information then helps determine whether the project goes forward and in what form. Human factors designers use simulations to learn about product usability. What may be intuitive to an engineer may not be intuitive to the public. Software engineers can see if their designs work in a prototype form. Combining focus groups, specification generation and documentation into continuing process speeds cycle time and increases productivity.

The replacement animation technique used by Red Sky to make a commercial for the Chili's restaurant chain is discussed. The commercial involves a chile pepper transforming into a mushroom butterfly and landing on the top of a plate of Chili's fajitas. The starting point was modeling a chili pepper in Alias/Wavefront's Maya to create all the necessary models and positions for the spot.

The promise of virtual prototyping is an intelligent computer-based model of products under development. The models will provide an accurate graphical image of the product, predict product behavior and simulate the manufacturing processes required to produce the product. Information derived from the model will also aid in cost estimation, identification of material requirements and marketing. The current 3D capabilities of CAD and CAE programs partially fulfill these goals, but technicological advances will be necessary before the promise of virtual prototyping is fulfilled. These include faster ways of performing finite-element analysis for design verification and easier ways of creating acceptable finite-element models for verifying these results. The elimination of finite-element meshing through the development of more intelligent solid and surface modeling techniques will also facilitate virtual prototyping.
