FIG. 1.

Idealised geometries of (a) a free symmetrical filament of length , and (b) an asymmetric '‘single-ended’' filament of length attached to a large drop, as typically generated during drop-on-demand printing.

Image of FIG. 2.
FIG. 2.

Examples showing (a) break up in the sequence 31, 36, 42, 46 and 51 (μs) and (b) full collapse in the sequence 28, 34, 40, 44, 46 (μs) of single-ended filaments of DEP. The black bars shown represent a length of 10 μm. Each image was recorded at the indicated delay time with ultra-short (20 ns) spark flash illumination; although each frame shows a different jet, the processes of jet ejection and collapse were highly reproducible.

Image of FIG. 3.
FIG. 3.

Behaviour of single-ended and symmetrical filaments generated from inkjet print-heads. Solid symbols denote filaments, which broke up into two or more drops, while open symbols denote cases where the filament condensed into a single drop. ●,◯: single-ended filaments; ▲,△: symmetrical filaments. Error bars arise from uncertainties in the filament diameter. The thin line represents the approximate values of observed in larger-scale symmetrical filaments and the thick line shows the predictions of the model described in the text (for α = 33).
