Inkjet printing is a nascent technology that developed during the last decades from only printing text and graphics into an important scientific research tool for R&D, where printers are used as a highly reproducible non-contact patterning tool. In contrast to lithography, inkjet printing is an additive technique that requires only small amounts of functional materials and, therefore, has a high materials efficiency. In particular, inkjet printing of metal nanoparticle dispersion has been used more and more during the last few years, in order to produce conductive features for plastic electronic applications.

Here, we present our recent results in the sintering of inkjet printed metal nanoparticles on polymer foils. In order to sinter the particles at speeds that are compatible with roll-to-roll speeds, we have used a combination of sintering methods. Conductivity values between 40 and 60% were obtained in a few seconds to minutes by using either photonic or plasma pre-sintering combined with microwave flash sintering.

  • 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.
