“Sometimes I feel like if you just watch things, just sit still and let the world exist in front of you – sometimes I swear that just for a second time freezes and the world pauses in its tilt. Just for a second. And if you somehow found a way to live in that second, then you would live forever.”
Material scientists at the Lawrence Berkeley National Laboratory have developed a technique to print three-dimensional structures made entirely of liquids. Using a modified 3-D printer, they inject streams of surfactant-sheathed water into silicone oil to form tubes of liquid within another liquid. The threads of water have been printed with diameters ranging between 10µm to 1mm with a variety of spiralling and branching structures. The researchers hope to use the technique to construct liquid electronics, perform molecular separation, or precisely deliver components to more complex structures.
