  • Patent number: 11059219
    Abstract: A system for manufacturing a three-dimensional article includes a resin vessel, a light engine, a support scaffold, and a positioning actuator. The resin vessel includes an opening closed by a transparent sheet with opposed upper and lower surfaces. The light engine is disposed below the transparent sheet and is configured to transmit or project radiation up through the transparent sheet for selectively curing layers of the resin over a build plane. The support scaffold includes at least one ridge having an upper surface that contacts the lower surface of the transparent sheet to reduce an unsupported width. At a first lateral position the scaffold blocks the radiation from reaching a first blocked region of the build plane. The positioning actuator is configured to laterally move the scaffold from the first position to a second position to allow radiation to reach the first blocked region of the build plane.

    Abstract: 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.
