The 3D Printed Jet Engine

[HardOCP News]

I wonder how long it will be before we are printing these things for commercial use? You might want to turn your speakers down when you watch the video.

I wonder how durable that is, if it's anywhere near the durability of a production engine then I can see that moving into the market for small scale applications such as RC and even light sports aircraft. Whether or not it can be scaled up to produce a full size jetliner engine will all depend on cost.

ah...my pc is louder than that is

Remember folks, this is a turbin engine, not a turbine engine.

what's a turbin engine

That thing is headed to the scrap pile. 33k RPM on something that big??? No-go.

Also, what was with that first test? A balance issue?

Notice the resonance on the second test?

An engine of that size should be around 110K-150K RPM, and you'll definitely hear the exhaust noise instead of a resonance.

That thing won't even fly. I also think the testing showed serious issues.

Hmmm.. I can't edit my post...

I wanted to add that this might be an interesting technology for some parts, but not for a whole engine.

don't be ignorant.

It's a type of engine that is powered by those things the terrorists wear on their heads.

This is about what I have come to expect from [H} ..... disgusting.

Hmmm, Never.
Centrifugal compress jets are only suited for APUs. Not the thrust making jet propels the aircraft.
The earliest generation of jet engines was similar to this but they were found to be extremely inefficient.
Really most all axle flow jet engines are descendants from the German BMW and Junkers engines that powered the ME262.

I'm laughing even harder at your reply than I did at my original post!
