Continuous Improvement: Performance and Reliability in Shear Mode Piezo Ink Jet Printing
Abstract:Since the introduction of the carbon edge shooter array, Spectra 256 jet products have been used in a variety of applications. The modularity of this design has allowed the development of a family of products based on a 128 jet carbon module. Improvements in performance mean that Spectra printheads can meet demanding applications with respect to duty cycle and image quality. Additional printhead enhancements have enabled the reliable jetting of a wide variety of jetting fluids, including solvent, aqueous, and wax-based inks.
The jet is activated using Spectra's proprietary shear mode piezoelectric driver. This method of DOD printing has no wear mechanism, allowing billions of actuations per jet with no measurable degradation. The robustness of this jet design has been demonstrated in a single pass printer using thousands of jets, firing at high duty cycles and line speeds. Life testing of these devices has demonstrated high reliability, in the laboratory and in the field. Test results discussed in this paper will include thermal cycling, jet actuation, ink immersion, and volume of ink jetted. All test results confirm the suitability of Spectra carbon array technology as a solution for high performance industrial applications.

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.
