CAD and the Rapid Construction of Physical Objects

  • Stefano Filippi


This chapter deals with the generation of the physical representation of objects modeled using 3D CAD systems. There are many technologies at the moment that perform this task in a quasi-automatic way. The resulting objects can serve as prototypes in each phase of the design process—in this case the specific term used is rapid prototyping—, or they could be tools for building products—rapid tooling—, or, in some case, they represent the result of the development, the final product—rapid manufacturing—. Then, the role of these technologies appears quite important throughout the whole product development process. They allow resource saving, better product quality, shorter TTM, etc., but at the same time they present specific requirements that inevitably end to influence the product design. Some design for manufacturing methods and tools have been developed and adopted in different fields, in order to help designers and engineers to keep these requirements into consideration. In the following, some technologies will be introduced; then their requirements are exploited to show the data elaboration needed to gain the compatibility with them; finally, some examples of adoption of these technologies in different fields will be reported.
