  • Manufacture of field activated components by stereolithography
    Publication number: 20090261287
    Abstract: There is disclosed stereolithographic manufacture of more complex components including at least one active material without the need for fabrication. Fabrication can introduce component discontinuities that hinder performance of the final component. Thus, some embodiments entail a method of manufacture for complex, field activated components such as piezoelectric or magnetostrictive sensors or actuators.

  • Buoyant plugs for liquid metal control
    Publication number: 20090255963
    Abstract: A method of initiating a pour of a liquid alloy comprises the steps of filling an interior of a crucible with a displacement plunger and the liquid alloy until a metal head of the liquid alloy exceeds a critical height. The crucible has a bottom pour opening with a plug inserted therein. The plug is configured to be buoyant within the liquid alloy when the liquid alloy is below the critical height. Pour is initiated by at least partially withdrawing the displacement plunger until the metal head drops below the critical height.
