Ink-jet printing for ceramic functional coating
Abstract:The interest of functional ceramics coatings based on low cost and flexible manufacturing has been pushed up by the effectiveness shown by the Chemical Solution Deposition (MODCSD) of metal-organic salts route, based habitually on the use of spin coating, deep coating or slot die techniques previous to the thermal treatment to achieve the decomposition of the starting salts. The possibility to implement effective Drop on Demand (DoD) systems in the manufacturing process allows a more efficient way to homogeneously extend the precursor solution over the substrate, being so able to control the thickness of the ceramic coating among other manufacturing advantages as control of solvent evaporation. In this work we report on our experiments concerning ink jet coating of functional complex ceramics as LSMO over single crystalline substrates by using a single nozzle piezolectric dispenser. Characterization of both, the rheological properties of the developed ink, and the resulting coating by XR diffraction, SEM, and magnetic behavior are reported.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
