ColorMod: Recoloring 3D Printed Objects using Photochromic Inks

We present ColorMod, a method for changing the color of a 3D-printed object even after fabrication. ColorMod works based on photochromic inks that can switch their appearance from transparent to colored when exposed to light of a certain wavelength. The color remains even when the object is removed from the light source. The process is fully reversible allowing users to recolor the object as many times as they want. To switch between different colors (e.g. red to yellow), we use a multi-color pattern with one color per voxel across the surface of the object. When recoloring the object, our system locally activates only those voxels with the desired color and deactivates all other voxels off. We describe ColorMod’s hardware/software system and the corresponding user interface that comes with a conversion tool for 3D printing as well as a painting interface that matches physical voxels with the desired appearance. We also contribute our own material formula for a 3D-printable photochromic ink. More Information: http://hcie.csail.mit.edu/research/co...
