FUJIFILM Dimatix Implements M-Class Printheads and VersaDrop Jetting Technolog

First Application of Shaped Piezo Silicon to Print
FUJIFILM Dimatix in its new Spectra-branded M-Class printheads uses Silicon MEMS technology to fabricate jetting structures on silicon wafers in much the same way that integrated circuits (ICs) are manufactured and combined this technology with its proprietary Shaped Piezo Silicon technology to attach the PZT crystal to a thin silicon membrane atop the ink channel to form the pumping chamber. Each module is fabricated as a single monolithic structure—a jetting module on a chip—featuring 304 nozzles precisely spaced in a single row of jets at 180 nozzles per inch. Each channel can operate independently to provide peak performance, jetting a nominal 10-picoliter drop size that can be custom tuned. Jetting velocity is approximately 8 meters per second with 10-centipoise inks, using a drive voltage of less than 30 volts.
