Abstract
A combustor assembly for a gas turbine engine and a method of additively manufacturing the same are provided. A combustor dome includes a combustor wall defining a hole and a circumferential groove defined within the combustor wall around the hole. A floating ferrule assembly is additively manufactured with the combustor dome and includes a ferrule positioned at least partially within the hole and defining a radial lip that is received within the circumferential groove to inseparably position the ferrule within the combustor wall. A build support arm is attached to the ferrule by a frangible connecting member, the frangible connecting member being breakable for separating and removing the build support arm from the ferrule.
