Novel Developments in Photonic Sintering of Inkjet Printed Functional Inks
In this contribution the photonic sintering process was investigated numerically and experimentally for the case of inkjet-printed aqueous copper oxide ink and a Pulse Forge®3200 X2 tool, both implemented onto a NovaCentrix roll-to-roll machine. Our finding support the assumption, that pulse shaping and, therefore, energy tailoring as a function of time, is essential for efficient conversion of wet copper oxide deposits into conductive copper with no impact on the underlying substrate. The paper presents and discusses the resulting electrical resistances of features processed with a conventional hybrid solution using IR-radiation for pre-drying as well as a single step drying and sintering using a single radiation source.

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.
