Abstract
A method includes forming a fluid conduit inside a heat shield in an additive manufacturing process, wherein a fluid nozzle is defined at a downstream end of the fluid conduit, and wherein the heat shield is formed about the fluid nozzle. The method includes removing powder from an interior passage of the fluid conduit and fluid nozzle and from an insulation gap defined between the heat shield and the fluid conduit and fluid nozzle. The method includes separating the heat shield, fluid conduit, and fluid nozzle from the build platform. The method includes shifting the fluid conduit and fluid nozzle to a shifted position relative to the heat shield, and securing the fluid conduit and fluid nozzle to the heat shield in the shifted position.
Claims15
A method comprising:
- forming a heat shield surrounding a fluid conduit and a fluid nozzle in an additive manufacturing process, the fluid nozzle being at a downstream end of the fluid conduit;
- removing powder from interior passages of the fluid conduit and the fluid nozzle and from gaps defined between the heat shield and the fluid conduit and between the heat shield and the fluid nozzle;
- separating the heat shield from the fluid conduit;
- separating the heat shield from the fluid nozzle;
- separating the heat shield from a build platform;
- separating the fluid conduit from the build platform;
- separating the fluid nozzle from the build platform;
- shifting the fluid conduit and the fluid nozzle to a shifted position relative to the heat shield;
- and
- securing the fluid conduit and the fluid nozzle to the heat shield in the shifted position.
