Title: Method for forming polymeric patterns, relief images and colored polymericbodies using digital light processing technology

Abstract: A method for precisely and efficiently creating three dimensional bodies, relief images or patterns, colored bodies, or a combination of these using photopolymers, photocolorizable polymers or photoresponsive coatings, in one irradiation step as disclosed. In particular this invention describes a method of generating objects or patterns with differential control of properties (depth, pore size, color, density, mechanical strength, hardness, degree of cross-linking, tackiness, etc.) such that the property varies across the xy array.
