ABSTRACT:
An improved method of forming three-dimensional objects comprises irradiating an uncured photopolymer by transmitting an effective amount of photopolymer solidifying radiation through a radiation transmittent material which is in contact with the uncured photopolymer. The transmittent material is a material which leaves the irradiated surface capable of further cross-linking so that when a subsequent layer is formed it will adhere thereto. Using this method multilayer objects can be made.
