“…This is due to the larger nozzle size, larger droplet volume, and slow ejecting velocity (<2 m/s) of the CCE method. In contrast, for other inkjet printing technologies, the droplet volume is smaller (<0.5 nL), and the droplet formation jet velocity is higher, ranging from 2.5 to 11.5 m/s . As a result, the CCE printing technology more easily prints satellite-free droplets in low Oh number situations.…”

“…The CCE technique has better applicability for low Oh numbers than conventional inkjet printing . Researchers generally use the Oh number to characterize the capability of the droplet printing device to print a broad range of liquids. , Previously, the Lian group experimentally proved that for a stable printable ink with inkjet printing technology, the Oh is between 0.07 and 0.25 . The Moon Group obtained that the Oh range of stable droplet printing by inkjet printing technology ranges from 0.06 to 0.48 through experimental methods .…”

The behavior of cavity collapse in liquids is of fundamental importance in natural and industrial applications. It is still challenging to use the phenomenon of cavity collapse ejection in on-demand droplet printing technology. In this study, we investigate the cavity collapse ejection phenomenon in the submillimeter to millimeter scale and demonstrate that the cavity capillary energy is a critical factor affecting the state of the generated jet. Based on this phenomenon, we developed a droplet printing technology that can print nanoliter satellite-free droplets from a millimeter-sized nozzle, which reduces the risk of nozzle clogging. Using this printing technology, we demonstrated the printing of a nanoparticle suspension with 60% mass loading. Finally, we also showcased the printing of various inks for different applications using this technology, demonstrating the printability of cavity collapse-ejection printing technology in functional inks and showing potential to be applied in scenarios such as bioassays, the electronics industry, and additive manufacturing.

“…Among the aforementioned modes, the bending mode has been the most common and most studied. 29 Jiao et al 49 investigated the effect of ink properties and voltage parameters on the formation of piezoelectric inkjet droplets. In their works, by observing the droplet formation of sodium alginate, alcohol, and gelatin inks, stable single droplet ejection of these inks has been achieved by adjusting the driving voltage amplitude and ejection frequency.…”
