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 ...

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 ...

If you remember old computer magazines (or browse them today), you’ll see that back in the late 1970s and early 1980s, you weren’t always sure what you were going to do with a computer. Games were a ...

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 ...
