Method Enables Electronic Components to be Printed Like Newspapers - Tech Briefs But this technique generates metallic circuits with rough surfaces, causing electronic devices to heat up and drain their batteries faster. Researchers have addressed both of these issues - roughness and low resolution - with a large-scale fabrication method that enables the forming of smooth metallic circuits at the nanoscale using conventional carbon dioxide lasers, which are already common for industrial cutting and engraving. The fabrication method, called roll-to-roll laser-induced superplasticity, uses a rolling stamp like the ones used to print newspapers at high speed.
