Changing the color of 3-D printed objects

29.01.2018 | MIT | news.mit.edu

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.

But imagine if that weren’t the case — if, for example, you could change the color of your smartphone case or earrings on demand. Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have gotten closer to making that a reality. In a new paper, they present ColorFab, a method for repeatedly changing the colors of 3-D printed objects, after fabrication.

Changing the color of 3-D objects

Using their own 3-D printable ink that changes color when exposed to ultraviolet light, the team can recolor a multicolored object in just over 20 minutes — and they say they expect that number to decrease significantly with future improvements.
