3D printing holds potential as a faster, cheaper alternative compared with traditional photolithography for the fabrication of microfluidic devices by replica molding. However, the influence of printing resolution and quality on device design and performance has yet to receive detailed study. Here, we investigate the use of 3D-printed molds to create staggered herringbone mixers (SHMs) with feature sizes ranging from ∼100 to 500 μm. We provide guidelines for printer calibration to ensure accurate printing at these length scales and quantify the impacts of print variability on SHM performance. We show that SHMs produced by 3D printing generate well-mixed output streams across devices with variable heights and defects, demonstrating that 3D printing is suitable and advantageous for low-cost, high-throughput SHM manufacturing.

Potential Applications

Paper-based microfluidic devices have recently received increasing attention as a potential platform for its low cost, portability and excellent compatibility with biological samples. A variety of fabrication technologies were employed, including simple photolithography, wax plotting, printing, inkjet etching, plasma etching and so on. Meanwhile, the potential applications of paper-based microfluidic devices in diagnostic, point-of-care (POC), and environmental monitoring were reported. We review the recent progress of fabrication technologies and the applications of paper-based microfluidic devices.

Novel Technique

We present a facile, rapid and cost-effective way to fabricate microfluidic devices in laboratory atmosphere, named as “foil assisted replica molding” (FARM). This novel technique involves use of Al foil, pen and an X–Y plotter to create plano-concave microchannels. We have also demonstrated in vitro applications of these devices.
