Particle Tolerant Architecture
The authors were challenged to design a pen that would be robust to particles with no degradation to manufacturing yield, pen fluidic performance, or print quality. The project started with simple hydraulic modeling, concept development, and peer review. Then design proliferation began. Since the pen was in manufacturing, the challenges normally present in an R&D project (no printer, no ink, no print quality standards, no printer drivers) were absent. Approximately 50 designs were created, built and tested in 6 months, leading to the successful design, which was ultimately patented. Since then, about ten other particle-tolerant architectures have been designed and introduced into manufacturing. The design concept has proved successful over drop weights from 5 to 150 nanograms. The concept not only guards against particles but facilitates control of drop trajectory and pen operating frequency.

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.
