High-speed printing and process performance metrics. (A) Custom-built desktop P2R printing system with a CNT stamp attached on a flat flexure and a PET film attached to a roller with a diameter of 5 cm. (B) Optical microscope image of Ag honeycomb pattern with minimum internal linewidth of 3 μm printed on a PET substrate at a printing speed of 0.2 m/s using the P2R system. (C) Comparison of speed and resolution of conventional printing technologies for electronically functional materials. Conventional processes include flexography, gravure, screen, and inkjet (8–24). Soft lithography includes μCP and nTP (25, 26, 57–59, 67–70); Nozzle-based high-resolution printing methods include direct writing and EHD printing (27, 62–64). Tip-based methods include DPN and polymer pen lithography (PPN) (28, 29, 60, 61). (D) Comparison of volume per unit length, lateral feature size, and thickness of ink that transfers to the substrate by single print (by mechanical contact or drop) in conventional printing technologies (8–24), compared to nanoporous flexographic printing, as shown in this paper.
