  • Patent number: 10894355
    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.

  • Patent number: 10792908
    Abstract: In a method of producing a 3D part using an electrophotography-based additive manufacturing system, a plurality of layers of a powder-based material are developed using at least one electrophotography (EP) engine. The developed layers are transferred to a transfer medium. The layers on the transfer medium are dried by heating the layers without fully fusing the powder-based material to itself using a dryer. This reduces a water content of the layers. The dried layers are heated on the transfer medium to at least a fusion temperature, at which the power-based material fuses together, using a pre-transfusion heater. The dried layers are then transfused together on a build platform using a transfusion assembly to build the part in a layer-by-layer manner.

  • Patent number: 10766194
    Abstract: The present invention concerns a reservoir assembly for use in three-dimensional (3D) printing for building a 3D object, which includes a top frame that may be filled with liquid material, and a tensioned film being held underneath the top frame. The tensioned film may be air permeable and elastic at the same time, wherein surfaces of the tensioned film are micro textured so that the tensioned film becomes optically clear when it contacts with the liquid material. The tensioned film minimizes the creation of bubbles between the top and bottom surfaces. This also helps blurring the boundaries thereby enhancing the surface finish of the fabricated parts.

  • Patent number: 10737479
    Abstract: 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.
