Abstract: A method is provided for additive manufacturing. This method includes monitoring a current to a recoater blade. The monitored current is compared to a predetermined current. An operation is initiated in response to the monitored current exceeding the predetermined current. Another method for additive manufacturing includes comparing a movement of a recoater blade to an expected movement. A single exposure sequence is initiated in response to movement of the recoater blade being different than an expected movement. An additive manufacturing system is also provided which includes a recoated blade and a control. The control is operable to identify resistance to movement of the recoater blade.

Abstract: A tube assembly that may be for a fuel nozzle of a fuel system of a gas turbine engine may have a first tube defining a first flowpath along a centerline, a second tube generally spaced radially outward from the first tube with a first void located between and defined by the first and second tubes, and a support structure located in the first void and extending between the first and second tubes. The support structure is constructed and arranged to minimize or eliminate thermal conduction between the tubes. The entire assembly may be additive manufactured as one unitary piece. One example of a method of operation may include designed-for breakage of the structural support due to thermal stresses thereby further minimizing thermal conduction between tubes.

Abstract: A method includes building a tubular object by a layer-by-layer additive manufacturing process. A structure integrally connected to the tubular object for supporting a portion of the tubular object is formed during building of the tubular object. The structure provides vibration dampening, heat shielding, heat transfer, stiffening, energy absorption, or mounting after the tubular object is built.
