<p>A method for forming three-dimensional objects comprises irradiating with a source (24) an uncured photopolymer (11) by transmitting an effective amount of photopolymer solidifying radiation through a radiation transmittant material (13, 16, and 23) with areas of different opacity (18-22) which leaves the irradiated surface capable of further cross-linking so that when a subsequent portion of solid object (25) is formed it will adhere thereto. In another embodiment other means of preserving subsequent cross-linking are used instead of the transmittant material. Using either method three-dimensional objects (25) can be made layer by layer or point by point.</p> |
