  • Patent number: 10549478
    Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize support surrounding structures in the process of building objects, as well as novel surrounding support structures to be used within these AM processes. The support structure surrounds at least a portion of the object with a continuous thickness of powder disposed between the support structure and the object, the continuous thickness of powder having a maximum thickness that does not exceed 10 mm.
    Type: Grant

  • Patent number: 10486362
    Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize connecting support structures in the process of building objects, as well as novel connecting support structures to be used within these AM processes. The connecting support structures include two fused connections to the object and an axial direction between the fused connections, a perimeter of fused material about the axial direction, and unfused powder or air completely surrounding the perimeter of fused material.

  • Patent number: 10357828
    Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize support leading edge structures in the process of building objects, as well as novel leading edge support structures to be used within these AM processes. The support structure is positioned adjacent the object between the object and a first side of the powder bed. The support structure has a shape that tapers outward in the direction from the first side to the object.

  • Publication number: 20060083985
    Abstract: An electrochemical cell such as an alkaline battery has improved shelf-life and manufacturability. The cell has a gasket for sealing an open end of a metal container of the battery that forms a seal with a current collector shank of the battery without introducing cracks or other defects in the gasket that can lead to failure of the seal over time. Moreover, the gasket is configured to fix the current collector relative to the gasket upon assembly with the gasket so that the components of the subassembly remain fixed in position relative to each other during manufacture. A method of assembling an electrochemical cell is also disclosed.
