After more than two years and an estimated $20,000, a research group in the mechanical engineering department has created the first 3D printer capable of printing LED lights. The venture was led by ...

Researchers at Princeton University have developed a 3D printer that can print LEDs in layers -- and it could one day print contact lenses that incorporate heads-up displays. Michelle Starr Science ...

Light painting, or taking a few RGB LEDs, a camera with a long exposure, and turning the world into Tron, has been around for a while. We haven’t seen many people using their household CNC machines ...

Like fingerprints, no 3D printer is exactly the same. That’s the takeaway from a new UB-led study that describes what’s believed to be the first accurate method for tracing a 3D-printed object to the ...

An LED 3D printer at Princeton has integrated quantum dot LEDs with a standard contact lens to create a device capable of projecting beams of coloured light. Essentially, an artificial eye. Though not ...
