This is an interesting follow on to previous NASA experiments in this area. This is a pretty significant part (the injector) to build using a 3D process. It is a rare case where 3D printing the part is both cheaper and faster than making it the traditional way (machining it). I would not say there are a lot of parts that fall into that category but there are some.
