Abstract
A method of producing a three-dimensional object having selected elements which are colored differently than other elements of the object comprising the steps of: (a) providing a film of a photohardenable composition containing a photoresponsive agent, (b) radiating the film in a cross-sectional pattern of the object to be formed, (c) selectively irradiating one or more portions of the cross-sectional pattern corresponding to the selected elements which are desired to be colored differently with radiation which activates the photoresponsive agent, the photoresponsive agent thereby producing color in or removing color from the selected irradiated portions of the cross-sectional pattern, (d) repeating steps a, b, and c to form successive adjacent cross-sectional pattern of the object, and (e) integrating the cross-sectional patterns together to provide the three-dimensional object, wherein the curing and coloring steps are conducted using actinic radiation.
