Figure 2. Evaluation of multi-material ink printability. (A) Phase diagram of the printability of PEDOT:PSS-PVA ink under different print nozzle sizes (90-410 μm) and different print pressures (50-300 μm); (B) Printed PEDOT:PSS-PVA ink line width vs. print speed (0-6 mm·s^-1) and printing pressure (100, 200, 300 kPa) for the print nozzle size of 210 μm and the print height of 0.1 mm; (C) PEDOT:PSS-PVA ink lines printed under different printing parameters; (D) Phase diagram of the printability of PVA ink under different print nozzle sizes (90-410 μm) and different print pressures (50-300 μm); (E) Printed PVA ink line width vs. print speed (0-8 mm·s^-1) and print pressure (100, 200, 300 kPa) for the print nozzle size of 260 μm and the print height of 0.1 mm; (F) PVA ink lines printed under different printing parameters. PEDOT:PSS: Poly(3,4-ethylenedioxythiophene):polystyrene sulfonate; PVA: polyvinyl alcohol.
