Hot embossing stamp fabricated from aluminumfilled epoxy resin can be employed for short-run productions. However, the cooling time is much longer compared to metallic stamps due to poorer thermal conductivity. Therefore, developing a hot embossing stamp with high cooling efficiency is an important issue. In this study, three different coolingchannel layouts were employed to fabricate hot embossing stamps using rapid prototyping and rapid tooling techniques. Effects of different hot embossing stamps on the cooling time during hot embossing molding were investigated. It was found that the reduction in cooling time about 92 % can be obtained when a hot embossing stamp with conformal cooling channels compared to the hot embossing stamp without cooling channels. The manufacturing cost reduction for a micro-featured hot embossing stamp with high cooling efficiency about 72 % can be obtained using the method proposed in this work.
