A Rapid Prototyping Technique for the Fabrication of Solvent-Resistant Structures



C Harrison, J Cabral, Christopher M. Stafford, Alamgir Karim, Eric J. Amis


We demonstrate a rapid prototyping technique for the fabrication of solvent-resistant channels up to and exceeding one millimeter in height. The fabrication of channels with such dimensions by conventional lithography would be both challenging and time-consuming. Furthermore, we show that this technology can be used to fabricate channels with a depth that varies linearly with distance. This technique requires only a long-wavelength ultraviolet source, a mask made by a desktop printer, and a commercially available optical adhesive. We demonstrate two lithographic methods: one which fabricates channels sealed between glass plates (closed-face) and one which fabricates structures on a single plate (open-faced). The latter is fully compatible with silicone replication techniques to make fluid handling device.
