(A) Impact of extrusion pressure on the printed filament width for conical nozzle tips with different inner diameters (200, 250, 410 µm) (B) for conical and needle-shaped nozzle with same ID (410 µm). Impact of printing speed on the filament width for different conical nozzle ID: (C) 200 µm, (D) 250 µm, and (E) 410 µm and (F) needle-shape nozzle ID:410 µm. PDMS printed configurations of (G) 10 mm × 10 mm × 3 mm (L × W × H) well array (H) cross shape (I) and grid well structure. Images of PDMS-based (J) microchannels, (K) concave well connected by channels, and a (L) Y-shaped micromixer derived from printed Pluronic molds. (M) Diagram of the Y-shaped micromixer, showing the positions where mixing between a red and blue solution were optically verified. (N) Images of red and blue solutions mixing for solution flow rates of 1,3, and 5 µl/min and at positions i, ii, and iii which indicate 10 mm,75 mm and 145 mm distance from the inlet respectively.
