Fig. 6. PEGDA-co-PEGMEMA peristaltic micropumps.
(a) Cut-away view of the 3D model of the micropump. (b) Microscope image of the 3P-printed multimaterial peristaltic micropump. Note that the valves are in an open state. (c) Flow rate versus phase interval T0 for 20, 30, and 40% PEGDA-co-PEGMEMA micropumps. (d) Maximum pressure delivery of the 3P-printed micropumps. Note that the thickness of the membrane in all micropumps is kept at 60 ± 10 μm. Moreover, the seats for the microvalves have a width of 300 μm. These wider seats provide a larger contact area for the membrane during rapid opening/closure.
