Abstract: A method and apparatus for making a three-dimensional object by solidifying a photohardenable material are shown and described. A photohardening inhibitor is admitted into a surface of a photohardenable material through a flexible film to create a "dead zone" where little or no solidification occurs. The dead zone prevents the exposed surface of the photohardenable material from solidifying in contact with the film. The inhibitor causes the film to deform along the build axis, thereby creating a non-planar interface between the photohardednable material and the film. A method is provided to compensate the three-dimensional object data based on the deformation of the film.

Abstract: Methods and apparatuses for making multiple three-dimensional objects from multiple solidifiable materials are shown and described. In accordance with the method, the objects are designed with variable removable support heights along the build axis so that each object has an interface between first and second materials that is the same height from the build platform. The technique simplifies the process of producing multiple three-dimensional objects from multiple solidifiable materials which may have different build axis heights of first and second finished object sections so that the sources of solidifiable materials need only be switched once during the building of multiple objects.

Abstract: An apparatus and method for making a three-dimensional object from a solidifiable paste is shown and described. The apparatus includes a pastes spreader, at least a portion of which extends into the solidifiable paste. The container holding the solidifiable paste and the spreader are movable relative to one another. In one system, the spreader vibrates as the container and the spreader move relative to one another. In another system, the spreader is part of a spreader assembly in which a first spreader and second spreader are angled with respect to one another, and the assembly is rotatable and lockable into multiple rotational positions. A paste dispenser is also described which is configured to dispense paste while moving along a travel axis. The apparatus and method allow three-dimensional objects to be progressively built upside down by ensuring that the previously solidified object section has a substantially homogeneous layer of solidifiable material available for forming a new layer of the solidified object prior to exposure to solidification energy.

Abstract: A dental arch model and method for making the same is shown and described. The dental arch model includes a connector having opposite ends that connect to a respective one of the arch legs. The connector has a three-dimensional shape but does not include a surface that is both planar and parallel to the base of the arch connector along more than two thirds of the arch connector's length. In certain examples, the connector is in the shape of a prism or a trapezoid. In other examples, the connector has an upper surface that is sloped relative to the base of the arch connector. The arch connector may also include a plurality of fluid passageways for allowing fluid flow from an interior area between the inner walls of the arch connector to a location outside of the connector.
