    摘要： 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.

    摘要： A solidification substrate assembly for making a three-dimensional object from a solidifiable material includes a solidification substrate assembly. In certain examples, the solidifiable material solidifies in contact with the solidification substrate, and the tilting of the substrate and/or or the use of a peeling member facilitates separation of the substrate from the solidified material. In other examples, the solidification substrate assembly includes a film that is adjacent to a rigid or semi-rigid layer. The solidifiable material solidifies in contact with the film, and a peeling member peels the film away from the solidified material. Intelligent solidification substrate assemblies are also described in which a force sensor determines when to expose the solidifiable material to solidification energy and/or whether to use a peeling member to separate the solidification substrate from a solidified objection section.

    摘要： A method and apparatus for making a three-dimensional object by solidifying a solidifiable material are shown and described. A photohardening inhibitor is admitted into a surface of a photohardenable material 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 a container bottom or film. As the solidified object areas get larger and the build platform speed increases, the dead zone increases which can cause the formation of channels in the resulting objects and delamination. A number of techniques including continuous/discontinuous mode switching, multiple illuminations of portions of the same layer, and the use of gray scaling are disclosed for regulating the size of the dead zone.
