GE aerospace fuel nozzle additive manufacturing case

Cited as the standard example of why additive manufacturing wins on functional complexity — twenty parts collapsed into one with internal cooling features that couldn't be machined.

Here's an example from the General Electric area, an aerospace fuel nozzle, very complex part. It's a structural material but it's a functional material. Remember I told you the other day, when you're doing pixel-by-pixel, you've got to have a functional advantage. Just tensile strength, yield strength and elongation are not going to cut it. You can usually make those things other ways. But when you need all these little holes and bosses and things, previously made from twenty different parts, there's a tremendous cost savings.
