Color-Changing 3D Printables Help Reduce Waste

Once objects are 3D printed, they're usually final - making a change will require a reprint. Now, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) introduce 'ColorMod,' a method for repeatedly changing the colors of 3D printed objects, after fabrication. Using a special 3D printable ink that changes color when exposed to ultraviolet light, the team can adjust the color of an object in just over 20 minutes.Tech Briefs spoke with Professor Stefanie Mueller, who led the development of the ColorMod research prototype.
