Micro-Three-Dimensional Patterning by Inkjet Printing of UV Curable Inks
Abstract:A UV curable ink serves as a model fluid to find a basic description of the formation of micro-three-dimensional patterns by inkjet printing. The ink was deposited on a rigid surface to form solid lines after irradiation with UV light. The dimensions of the resulting patterns were analyzed with regard to the following settings varied: (1) drop spacing; (2) number of active nozzles; (3) orientation of the lines parallel or perpendicular to printing direction; (4) number of layers printed on top of each other. In addition, two different time-modes of the irradiation with UV light were applied to investigate the influence of printing ‘wet-in-wet’ or ‘wet-in-dry’: either the irradiation was carried out in one step after the complete printing process or in multiple steps during the printing process. The reported results contribute to understand the formation of functional patterns by inkjet printing in general. Furthermore, based on previous works we show examples like microsieves in which UV curable inks can be applied to create functional patterns.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
