Commercially available 3D printers may not be capable of 3D printing your next smartphone, but that doesn’t mean that researchers aren’t working on it. A team of scientists at Princeton University have made a breakthrough in the 3D printing of functional electronic components, according to Nanowerk. By creating their own 3D printer and carefully choosing a number of five different materials, the team was able to 3D print functioning quantum dot LED lights.
Published in Nano Letters, the team’s report, “3D Printed Quantum Dot Light-Emitting Diodes”, outlines the process by which the team was able to, layer by layer, combine five unique materials into a single LED. Assistant professor of mechanical and aerospace engineering at Princeton University, Michael McAlpine, explains to Nanowerk, “The big push in 3D printing these days is to try to print two or more polymers at once.…
