CHARM3D Printing 1 (IMAGE) National University of Singapore Caption Researchers from the National University of Singapore (NUS) have developed a cutting-edge 3D printing technique known as tension-driven CHARM3D, which is able to print free-standing metallic structures without the need for support materials and external pressure. This new technique fabricates 3D electronic circuits faster and with greater level of detail and accuracy.
