摘要： An apparatus for fabricating integral three-dimensional objects from successive layers of deformable and photoformable compositions by exposing the layers of the composition through a tensioned, elastomeric transparent film, in a way that the weak bonds between the film and each newly solidified layer are broken by changing the tension on the film, thus allowing a new layer of deformable composition to be introduced between the film and the solidified layer.

摘要： Apparatus and methods for modulating light involving the formation of bubbles in a normally opaque dye solution contained within a cell. The bubbles are created in the dye solution by focusing a beam from a laser in regions of the dye solution thereby vaporizing a solvent in the solution. When the bubble is formed, the modulator becomes substantially transparent in the region of the bubble. If the focused laser beam is turned off, the bubble condenses and the modulator again becomes opaque in the region of the condensed bubble.

摘要： An apparatus and method for fabricating integral three-dimensional objects from successive layers of photoformable compositions by exposing the layers of the composition through a detachable flexible transparent film, one side of the film being in contact with the composition and the other side of the film with a rigid transparent plate, which guides and supports the film.
