Researchers find technique for 3-D printing on nanoscale that can correct mistakes

University of Dayton physics and electro-optics researchers Md Shah Alam, Qiwen Zhan and Chenglong Zhao have created a less expensive 3-D printing method on a nanoscale, or a thousand times smaller than a human hair, that can manufacture nanostructures and erase mistakes. Top nanotechnology journal Nano Letters published their findings.
