In recent years, rapid prototyping technology (RPT) has been implemented in
many spheres of industry, particularly in the area of product development.
Existing processes provide the capability to rapidly produce a tangible so
lid part, directly from three dimensional CAD data from a range of material
s such as photocurable resin, powders and paper. This paper gives an overvi
ew of the growth and trend of the technology, areas of applications and its
significant benefits to manufacturing industries.
