A method for manufacturing an inlet frame (54) of a gas turbine engine (10), the method comprising:depositing a layer of additive material on a bed of an additive manufacturing machine; andselectively directing energy from an energy source onto the layer of additive material to fuse a portion of the additive material and form the inlet frame comprising:a forward annular body (102);a rear annular body (104) spaced apart from the forward annular body (102) to define an inlet passageway (106);an annular heating plenum (84) defined by the forward annular body (102); anda fluid supply conduit (138) defining a hot fluid passageway, the hot fluid passageway providing fluid communication between the annular heating plenum (84) and a hot air source (150) for providing a flow of heated fluid to the annular heating plenum (84).
