| Imagine one day in the future Maybe you could change the color of your smartphone case or other accessory to match your everyday dressup, thanks to a new study by the Massachusetts Institute of Technology Computer Science and Artificial Intelligence Laboratory (CSAIL) , This vision may come true.Scientists have created a new system called ColorFab that allows the color of 3D printed objects to be repeatedly changed after they are created.  When printed with new technology, they consist of voxels (voxels) containing red, yellow, or blue light-sensitive dyes, all rendered voxels when exposed to ultraviolet light, With the exception that all voxels remain 'on' when the dye is exposed to sufficiently intense visible light, the dye can be 'turned off' and become transparent.With this in mind, all voxels are 'turned on' using UV light After that, some of these voxels are selectively 'closed' by projecting the visible light pattern onto the object. For example, if all the red and yellow voxels are 'off', only the blue voxels will remain shaded, causing the object to appear blue Although the resolution of this system is still relatively low, the researchers hope Once it becomes clearer, it can be used to create other colors. Although the entire process of discoloration currently takes 23 minutes, scientists believe they can get shorter times by using more powerful projectors or incorporating more dye.Furthermore, although the technology so far has been limited to the production of plastic products, it may eventually be Used to make ColorFab clothing. Stefanie Mueller, assistant professor in charge of the study, said: 'In general, people consume more and waste more than they did 20 years ago, and you do not have to create a whole new one each time by changing the color of the object.
