ABSTRACT

Recently, ink-jet printing technology has been applied for various industries such as semiconductor, display, ceramictile decoration. Ink-jet printing has advantages of high resolution patterning, fast printing speed, high ink efficiency andmany attempts have been made to apply functional materials with excellent physical and chemical properties for the ink-jetprinting process. Due to these advantages, research scope of ink-jet printing is expanding from conventional two-dimensionalprinting to three-dimensional printing. In order to expand the application of ink-jet printing, it is necessary to optimize therheological properties of the ink and the interaction with the substrate. In this study, photo curable ceramic complex inkcontaining nano silica particles were synthesized and its printability was characterized. Contact angle of the photo curablesilica ink were modified by control of the ink composition and the surface property of the substrate. Effects of contactangle on printing resolution and three-dimensional printability were investigated in detail.
