Abstract

A method includes forming a fluid conduit (102) inside a heat shield (104) in an additive manufacturing process, wherein a fluid nozzle (124) is defined at a downstream end of the fluid conduit (102), and wherein the heat shield (104) is formed about the fluid nozzle (124). The method includes removing powder (106) from an interior passage (110) of the fluid conduit (102) and fluid nozzle (124) and from an insulation gap (112) defined between the heat shield (104) and the fluid conduit (102) and fluid nozzle (124). The method includes separating the heat shield (104), fluid conduit (102), and fluid nozzle (124) from the build platform (108). The method includes shifting the fluid conduit (102) and fluid nozzle (124) to a shifted position relative to the heat shield (104), and securing the fluid conduit (102) and fluid nozzle (124) to the heat shield (104) in the shifted position.
