Optimized 3D Resin Printing for Microfluidic Chip Fabrication

Abstract

This paper presents and evaluates printed microfluidic chips using a consumer-grade resin printer. Two fabrication approaches are explored, focusing on the detailed fabrication workflow of open-channel and embedded-channel-based Tesla mixers, followed by a chamber for electrochemistry . The structure of fabricated chips was evaluated using optical and scanning electron microscopy and consequently tested by dye channel visualization . Furthermore, the chips had bulk electrodes for three-electrode cyclic voltammetry measurements. The solution flow was controlled using an automated microfluidic workstation .
