Method and computer-readable model for additively manufacturing an injector assembly or a ducting arrangement including such assembles, as may be used in a combustion system of a gas turbine engine. The injector assembly may include a reactant-guiding structure (42) that may be configured to define a curvilinear flow path (47) to route a flow of reactants from a first flow direction (50) to a second flow direction (52) toward a cross-flow of combustion gases (60). A cross-flow guiding structure (54) may further define a flow path (58) to route a portion of the cross-flow of combustion gases toward an outlet side of the cross-flow guiding structure. Disclosed injector assemblies can be configured to reduce pressure loss while providing an effective level of mixing of the injected reactants with the passing cross-flow. Respective injector assemblies or the entire ducting arrangement may be formed as a unitized structure, such as a single piece using a rapid manufacturing technology, such as 3D Printing/Additive Manufacturing (AM) technology.
