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 ...

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 ...

[Dave] just couldn’t take the ambient noise from his Lulzbot Mini anymore, so he built a fancy fan controller for it. He measured some points on the printer’s Rambo controller board to see what ...

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 ...
