3D printing is gaining popularity in manufacturing and for home users, but its application is pretty limited. Applying 3D printing technology to semiconductors could be a whole new way of revolutionizing products we use every day. A team of researchers at Princeton University has created Quantum Dot LEDs with a 3D printer.
This opens the door for numerous advances, such as weaving small devices into fabrics or even printing them on surfaces. This can eventually be used for smart contact lenses and many medical applications.
