Abstract

Micromixers have been widely used due to its vast applications in biological, chemical, electronics, and mechanical fields. Micromachining through common fabrication methods is a challenging issue, therefore it is emerging as the latest research area. This work presents the rapid and cost-effective method of micromixer fabrication. It includes two steps of fabrication. Initially, a mold of spiral micromixer is fabricated on an aluminum workpiece using wire electrical discharge machining (Wire-EDM). In the Wire-EDM process, molybdenum wire of diameter 180 µm is used as a tool electrode. Pulse-on-time (Ton) of 15 µs, pulse-off-time (Toff) of 6 µs, peak current (IP) of 4 A and table feed (S) of 55.6 m/s are set as the cutting parameters. After machining the mold, in the second step final micromixer is fabricated using soft lithography technique with poly-di-methyl-siloxane (PDMS). It is confirmed by visualizing the flow inside the fabricated micromixer that a spiral micromixer may be used for mixing for various applications.
