Casey Glick is a fourth year Physics PhD student working in Professor Liwei Linís laboratory. He received B.S. degrees in Applied Physics and Geochemistry from the California Institute of Technology in 2011, and a M.A. in Physics from UC Berkeley in 2013. He is currently supported by the National Science Foundationís Graduate Research Fellowship, and was the 2010 recipient of the Caltech-Intellectual Ventures Invention Prize. Caseyís research focuses on microfluidic circuitry, where fluids are used as direct analogs of electrical circuits, and on using 3D-printing for advanced microfluidic fabrication.
3D-Printed Molds for Rapid Assembly of PDMS-based Microfluidic Devices [BPN787]
In this work, we demonstrate the use of 3D-printed molds for fabricating PDMS-based microfluidic devices. 3D Printing allows for the fabrication of molds that are not monolithic in structure, and therefore represents a significant improvement over the capabilities of standard soft lithography; with 3D-printed molds, we can fabricate most features commonly generated by soft lithography in addition to formerly difficult features such as domes and variable-sized channels. Furthermore, we demonstrate that this technique can be used to generate microfluidic devices molded on both sides - which allows for single-step generation of features like vias and thin membranes - and can be easily adapted to generate multi-layer microfluidic structures.
