  • Gas dispersion for additive manufacturing
    Patent number: 11433488
    Abstract: A gas-dispersion apparatus for an additive-manufacturing apparatus includes a pipe defining an axis, an outlet, and a cooling tube coiled about the pipe. The pipe includes a passageway along the axis, and the pipe extends from a first end to a second end. The outlet is positioned to discharge gas into the passageway at the first end. The first end is attachable to a laser so that a beam emitted by the laser travels along the axis.
