3D printing with non-toxic liquid metal gallium and indium alloy. Printed neat as little droplets or slowly extruded from a syringe, the liquid forms a skin that gives it a little structure. However, if it can be incorporated into plastic and rubber 3D printers then it could provide a way to print electrical circuits within plastic objects and even enable bendable circuits to be created within rubberised materials. Gives another meaning to circuit bending.
