Abstract:The fabrication of microfluidic devices has progressed from cleanroom manufacturing to replica molding in polymers, and more recently to direct manufacturing by subtractive (e.g., laser machining) and additive (e.g., 3D printing) techniques, notably digital light processing (DLP) photopolymerization. However, many methods require technical expertise and while DLP 3D printers remain expensive at a cost ∼15-30K USD with ∼8M pixels that are 25-40 µm in size. Here, we introduce (i) the use of low-cost (∼150-600 US… Show more
