A novel printing technique designed by engineers at Harvard University in Massachusetts is revolutionizing 3D printing with liquids,reports Live Science.
Described in a study just published in the journal, Science Advances, and this brand-new technique goes by the name of acoustophoretic printing and allows scientists to print liquid droplets of incredible high viscosity — something deemed impossible until now.
According to the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS),current methods of printing liquid droplets, such as inkjet printing, or only work on substances that are 10 times more viscous than water at the most. This excludes a wide array of materials used in the food and pharmaceutical industries,which possess a considerably higher level of viscosity.
For instance, biopolymer and cell-laden solutions used in biopharmaceuticals and bioprinting are at least 100 times more viscous than water, and notes SEAS. At the same time,some sugar-based biopolymers near close to the viscosity of honey, which is 25000 times more viscous than water.
