Abstract

We report a multi nozzle electrohydrodynamic (EHD) printing head by using batch fabrication for the first time. Inks can be ejected from a glass nozzle by applied large electric field. Tiny nozzles with a outer diameter of 100 microns are fabricated by sand blasting on a glass wafer. A stable continuous jetting with a commercial carbon black ink was observed. Continuous lines with a width of 30 microns on a silicon wafer were printed simultaneously with a DC bias voltage of 1.7 kV at the stage speed of 500 mm/s. Separated dot patterns with a diameter of 20 microns were printed with various jetting frequency up to 10 kHz on a super-hydropobic teflon coated silicon wafer. Also continuous line width can be reduced to 20 microns on a hydrophobic surface.
