3-D color stereophotolithography is based on the classic laser stereophoto-lithography technique, but it needs several reactors containing colored resins instead of just one containing a commercial resin. By moving the incident laser beam in each reactor for each color, one can create color parts of very fine quality. This could be applied to the manufacture of 3-D color objects conceived in the computer-aided design process. This new technique should be very attractive in fine arts, architecture, etc.
