Rapid prototyping (RP) has been used for design verification and proto sample or mold manufacturing. Many RP systems have been introduced into the market during the past 15 years. However, until now, the systems have used mainly for external physical models (mono function), and have the basic but critical limitation of one material on one stage (mono material). To overcome the limitations of mono-material and mono-function of conventional RP systems, the concept of Functional Prototype Development (FPD) is newly proposed in this paper. FRD provides the necessary prototype functions such as mechanical, optical, chemical and electrical properties in order to meet the broad requirements of the industry. The paper illustrates the representative achievements of electronic components such as inner visible multi color prototype and the multi-layer printed circuit board (MLB). Experimental results demonstrate that FPD has great potential applied to broad industrial uses and that it will be a powerful tool in the near future.
