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.
This is no ordinary pen. It’s the Lix 3D pen, which enables you to draw thin 3D structures from a flexible plastic straight in the air as easy as drawing a picture with a biro. It is in high demand by all sorts from architects to artists. I extracted this GIF from an email I received at work.
