You can use 3D printing technology to make a few electronic products such as antennas and batteries, but semiconductors and light-emitting diodes have been elusive. You usually need some other manufacturing techniques to make these products. A group of researchers in Princeton recently solved this problem. They have found a way to manufacture quantum dot LEDs using only 3D printers. Scientists choose printable electrodes, polymers and semiconductors that dissolve in solvents to prevent them from damaging the underlying layers during printing. After this, the team used design software to print materials and mix them. In this case, many tiny LEDs are manufactured, and you can print them into many objects, including curved surfaces. wenzhou gugao international trade CO.,LTD. , https://www.gugaotrade.com
Researchers believe that the current technology can be used to make smart contact lenses with built-in displays. But this is just the beginning. This method can be used in cooperation with other semiconductors and can be used to combine solar cells, transistors and other electronic products, which was previously impractical or impossible. Before these things could happen, the Princeton University scientists would have to improve the resolution and performance of their 3D printing technology.
