Scientists have developed a three-dimensional printing using liquid metal
Researchers have developed a technology for three-dimensional printing methods to create freestanding structures of the liquid metal at room temperature. "It is difficult to create something whole of the liquid, since any liquid tends to take the form of one or more drops. However, we found that the liquid metal alloy of gallium and indium reacts with oxygen at room temperature to form a shell that allows the stored form of liquid metals, "says Associate Professor Michael Dickey of the University of North Carolina, co-author of the study.
Scientists have developed multiple methods for creating such structures which can be used to connect electronic components in three dimensions. One technique involves laying droplets of liquid metal at each other, like oranges on the counter of the supermarket. Droplets adhere to each other, but retain their shape and are joined into a single large drop. Another technique introduces molten metal to the polymer template so that the metal takes the form of a. Also, scientists developed methods of making wiring of the liquid metal which retain their shape even when held perpendicular to the base.
The results were published in Advanced Materials. kind This "skin" does not only form a stable printed objects, but also keeps the alloy in the liquid state. Thus printed from a liquid metal with help of 3D-printer object can be coated with a polymer that can hold its shape for a long time. For the foreseeable future, this technology can help in the creation of flexible and elastic wires, which have been shown by researchers from the University of North Carolina in December 2012 year. Development will also find use in biocompatible tissue electrode.
