Technology push and market pull lead to an intensification of micro molding processes development which have variety of applications such as micro-gears, micro-pumps, micro optical components, connectors, wave-guides, optical gratings and mass production of polymer micro parts and structures with high aspect ratios. In these recent years, broad range of microfabrication technologies including, laser ablation, photolithography, lithography, electroplating, and molding (LIGA), chemical etching have been developed. Most of these technologies have been developed for mass production. Manufacturing industry is however more and more facing the problem of producing personalized parts, resulting in low volume production. New technologies to allow economical fabrication of low volume micro-parts become a need.
