Abstract

Undergraduate STEM student performance is greatly benefited by supplementary, hands-on laboratory experience. Micro and millifluidic devices provide a multitude of opportunities for interactive study of concepts and phenomena encountered in nearly every field of engineering, as well as in chemistry, biology, and other disciplines. Unfortunately, due to the cost and difficulty of standard micro and millifluidic device fabrication methods, many undergraduate students do not have access to these versatile educational tools. Luckily, 3D printing offers an inexpensive and simple solution to this issue. This work aims to demonstrate the capability of stereolithographic (SLA) 3D printing for the fabrication of micro and millifluidic devices for use in undergraduate engineering studies at the University of Tennessee at Chattanooga (UTC); the ultimate goal of the work is to enhance student performance though the active study of concepts encountered in courses and undergraduate research projects. The work presented in this paper details the fabrication and analysis of various micro and millifluidic devices produced with a Formlabs Form1+ SLA printer, the initial results obtained through the use of the printed devices, and future plans for the continued integration of this technology into courses and undergraduate research at UTC. Initial experiments with these devices were intended to demonstrate 3D printing capabilities and potential utilization of the printed devices in studies and demonstrations related to fluid mixing, biodiesel production, and droplet generation. These applications were chosen for their relatability to topics covered in various engineering courses and potential for use in research at UTC.
