Researchers create faster and cheaper way to print tiny metal structures with light

Posted by in categories: engineering, nanotechnology

Researchers at the Georgia Institute of Technology have developed a light-based means of printing nano-sized metal structures that is significantly faster and cheaper than any technology currently available. It is a scalable solution that could transform a scientific field long reliant on technologies that are prohibitively expensive and slow. The breakthrough has the potential to bring new technologies out of labs and into the world.

Technological advances in many fields rely on the ability to print metallic structures that are nano-sized—a scale hundreds of times smaller than the width of a human hair. Sourabh Saha, assistant professor in the George W. Woodruff School of Mechanical Engineering, and Jungho Choi, a Ph.D. student in Saha’s lab, developed a technique for metal nanostructures that is 480 times faster and 35 times cheaper than the current conventional method.

Their research is published in the journal Advanced Materials.
