The vision to 3D-print fully functional devices that contain multiple materials in a press of a button has come a step closer to reality. Researchers from the University of Nottingham – UK have developed a method to 3D print structures that contain electrically-conductive silver inks and insulative polymeric inks in a single process. The key to this innovation is a new method to solidify metallic and polymeric inks rapidly using a single source of energy, a UV light. The challenge...
