Abstract
An improved method of forming three-dimensional objects comprises irradiating an uncured photopolymer by emitting an effective amount of photopolymer solidifying radiation directly into a desired area inside of uncured photopolymer using an immersed radiation guide. The radiation is emitted through a material which leaves the irradiated surface capable of further cross-linking so that when an adjacent area is irradiated, it will adhere thereto. Repeating the irradiation for all areas in desired sequence, any three-dimensional object can be made; depending on the size of the emitted beam and the amount of emitted energy, objects can be formed point by point, post by post, area by area or layer by layer.
