Solved: one of the ink-jet printing industry's greatest challenges
The research, published in the journal Physical Review Letters, could aid in designing processes for paint-spraying, ink-jet printing and the dispersion of drugs for inhalation.
Dr Alfonso Arturo Castrejon-Pita, first author of the paper, said: “For the first time in an experimental and quantitative way, the ultimate behaviour of a filament under nothing but the action of viscous and surface tension forces has been explored.”
One of the greatest challenges facing the ink-jet printing industry is to develop print-heads that are capable of generating “clean” single, uniform size droplets within a large range of fluid properties (viscosity, surface tension).
Led by Professor Ian Hutchings, the team developed a large-scale, fully controlled model of a print-head to recreate the process of droplet generation.
