Take apart a few old DVD drives, stitch them together with cable ties, add a pen and paper, and you’ve got a simple CNC plotter. They’re quick and easy projects that are fun, but they d… ...

Based on polar coordinate, the BUAA researchers developed a printing setup with a rotating mandrel as the substrate, called Polar-coordinate Line-projection Light-curing Production (PLLP) technology.

His tests open up some interesting possibilities in the world of blinkey LED stuff, including a polar coordinate display that would be perfect for low-res games and LED clocks.
