As one of the direct write technologies, electrohydrodynamic jet printing was used in obtaining fine ceramic lines. We used pin electrodes of various diameters, each of which was located below the substrate, and analyzed the effects of pin diameter on Al2O3 nanoparticle one- and two-dimensional patterns formed with pin (nozzle)-to-pin (ground) electrodes. The onset voltage required to start the formation of a pattern for a 1-μm-diameter electrode was fourfold lower than the voltage required for a 1000-μm-diameter electrode. Additionally, an Al2O3 nanoparticle pattern with a uniform width as fine as 25 μm was obtained despite using the very large diameter of the nozzle (920 μm) used.
