Abstract

Rapid prototyping (RP) is a technology and apparatus for fabricating physical objects directly from parts created in CAD using additive layer manufacturing techniques without manufacturing process planning, tooling, or fixtures. Early RP machines were used to produce models and prototype parts; today, they are much more widely used, even for small runs of production-quality parts. Some RP technologies now support microscopic manufacturing, largely in microelectronics as well as in optoelectronics fabrication. In this chapter, several major areas of rapid prototyping are introduced, including design, manufacturing, art, medical science, and bioengineering. Overall objectives include (1) a general understanding of RP technology and the various machines available commercially, (2) familiarity with emerging RP and its applications in micro-manufacturing and other fields, and (3) application of basic principles and methods through case studies.
