A duct assembly for a fuel injector of an engine includes a base and multiple duct bodies. The base includes a number of spaced apart receptacles. Each receptacle defines a cavity with a receptacle axis, a rotational engagement surface, and an axial engagement surface. The duct bodies are correspondingly secured within the cavities. Each duct body defines an axis and a duct extending along the axis to provide a passage for a fuel jet from the fuel injector. Each duct body defines an axial alignment surface engaging the axial engagement surface of the receptacle in which it is disposed to axially align the duct body along the receptacle axis of the corresponding receptacle.

A method for evaluating part for additive manufacturing is provided. The method includes receiving data related to a set of printability factors associated with the part. The set of printability factors comprise at least: an availability of a three dimensional printer, a build density, a fraction of part to be printed, a print accuracy, a part complexity, and a number of parts needed. The method includes evaluating a printability index associated with the part based on at least three printability factors from the set of printability factors. Further, the method includes displaying the printability index associated with the part for the evaluation of the part for additive manufacturing.
