After years of research, one team may finally have accomplished a far-reaching goal of the 3D printing world. Michael McAlpine and his team out of Princeton University have 3D printed an entire functioning quantum dot LED. Quantum dot LEDs are not quite the same as LEDs in consumer electronics like TV and computer screens, but they are similar -- just more durable, efficient, and flexible, as well as maintaining very high color purity. Five materials are layered together using a custom 3D printer to create these LEDs; they are 100% 3D printed into one single object during fabrication, which is a very important first. The success of this project may just have far-reaching implications across a broad spectrum of industries and may even lead to one day 3D printing your own TV, computer screen, smartphone, or other technologies right at home.
