Replication for Microstructure Using Soft Mold

Article Preview

Abstract:

In this paper, a new replication technique for 1D, 2D, and 3D microstructure was introduced, in which a master pattern was made of photo-curable epoxy using microstereolithography technology, an etching process, and a dicing process. Next, it was transferred onto an epoxy. Barrier ribs were selected as the 1D microstructure, and a rectangular pattern was selected as the 2D microstructure. A helical gear was selected as one of the real 3D microstructures for this study, and these were replicated from pure epoxy. In addition, the life span of the soft mold for using the micro replication process was evaluated.
