  • Patent number: 11104117
    Abstract: An apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device is shown and described. The apparatus includes a solidification substrate that is tiltable relative to a film about a tilting axis. Layers of the solidifiable material solidify in contact with a film located between the most recently solidified object layer and a solidification substrate that comprises the solidification substrate assembly. The tilting of the solidification substrate relative to the film allows the substrate to be used to squeeze excess solidifiable material from between the film and the most recently solidified object surface while minimizing or eliminating the formation of bubbles in the solidifiable material which can prolong object build times.

    Abstract: Techniques for measuring a position of a build platform in an additive fabrication device are provided. Such techniques may include detecting the onset and/or dissipation of force applied to a build platform as it moves from being in contact with, to being out of contact with, a container. In some embodiments, the techniques described herein may be applied in a stereolithographic additive fabrication device. According to some embodiments, measurement of forces applied to a build platform may be used to provide for reliable and consistent measurements of the height of the build platform relative to a container by measuring such forces at various positions of the build platform and analyzing the pattern of the forces with distance from the container.

  • Patent number: 11007708
    Abstract: Methods and apparatus for the inspection of cured layers of an object during the fabrication of the object using a 3D printing system. A just-printed layer is inspected by pressing the layer against a pressure sensitive surface in order to collect information about the layer. A tank contains a photo-curing liquid polymer, and at its bottom are pressure sensitive elements (e.g., in a backing member or mask). An extraction plate to which the object is affixed is adjusted so as to position a surface of the object adjacent to the pressure sensitive elements, which report a pressure distribution (e.g., by virtue of a force exerted by a localized region of the object on a localized region of the pressure sensitive elements).

  • Patent number: 8727758
    Abstract: A mold device for forming a plastic container from a preform. The mold device comprises a mold defining a mold cavity and a central exterior rod system moveably disposed within the mold cavity. The central exterior rod system is positionable between an extended position engagable with the preform and a retracted position spaced apart from the preform. The central exterior rod system maintains a central orientation of the preform during formation.
