3d.printingx299_0

A 3-D printer can already make a prototype or spare part out of metal or polymer. Researchers at Princeton University have now taken an important step toward expanding the technology’s potential by developing a way to print functioning electronic circuitry out of semiconductors and other materials. They are also refining ways to combine electronics with biocompatible materials and even living tissue, which could pave the way for exotic new implants.
