Abstract
The instant invention is directed to related methods of producing a three-dimensional object by dispensing sheets of a material, capable of physical transformation upon exposure to synergistic stimulation, onto a substantially flat working surface of a previous cross-section. In one preferred embodiment, sheets of a photoresist are employed which change solubility upon exposure to electromagnetic radiation. In other preferred embodiments, non-photoreactive sheets are employed, which ablate upon exposure to infrared radiation.
