Abstract

© 2014 AIP Publishing LLC. Drop-on-demand (DoD) ink-jetting of hard particle suspensions with volume fraction f ~ 0.25 has been surveyed using 1000 ultra-high speed videos as a function of particle size (d 90 = 0.8-3.6 μm), with added 2 wt. % acrylic (250 kDa) or 0.5 wt. % cellulose (370 kDa) resin, and also compared with Newtonian analogues. Jet break-off times from 80 μm diameter nozzles were insensitive (120 ± 10 μs) to particle size, and resin jet break-off times were not significantly altered by > 30 wt. % added particles. Different particle size grades can be jetted equally well in practice, while resin content effectively controls DoD break-off times.
