3D Printing Progress
Custom ink, ultraviolet light to repeatedly change an object's colour

3-D printing has come a long way since the first rapid prototyping patent was rejected in 1980. The technology has evolved from basic designs to a wide range of highly-customizable objects. Still, there's a big issue: Once objects are printed, they're final. If you need a change, you'll need a reprint.
