Demonstration of 3D-printed 2D and 3D microfluidic chips with a DLP-based printer: (a,b) directly printed 2D microfluidic chips, scale bar = 5 mm; (c) directly printed 3D microfluidic chip, with a three-dimensional helical channel structure, scale bar = 10 mm; (d,e) microfluidic chips based on an open-channel design and transparent encapsulation with adhesive tape, scale bar = 5 mm; and (f) micro-mixer based on an open-channel design and transparent encapsulation with adhesive tape, scale bar = 5 mm, with the locally magnified image showing the details of the channel structure, scale bar = 400 μm.
