John,
You are right, on the surface this seems very elementary for GE, but this just may have been a 'proof of concept' for them; and if so, it was a good one. If it was an attempt for a top-shelve unit, they failed badly, but I suspect it is the former.
I just wish they would have shown more of the process and which parts were actually printed. It also appears they only ran the engine on propane (not sure though), and only running to 33K (idle) would support that if there wasn't any lubrication for the bearings. In any case, for someone not involved in the 3D printing field like myself, it is still amazing to see what is possible even it is "elementary" at the moment.
