Researchers from Brigham Young University (BYU) in Utah have developed the first working microfluidic device that’s small enough to be effective at a scale less than 100 micrometers using 3D Printing Technology. The key focus involved building their own 3D printer to print at a much higher resolution and using a new, specifically designed, low-cost, custom resin. Also, the digital light processing stereolithography (DLP-SLA) helped them seek low-cost approach for project.
