I mean, we 3d print aerospace engine parts, is this "common sense" logic really true?

The 3D printing they do for aerospace engine parts is certainly very much different from how most metal 3d printing is done. Because the requirements are completely different, and the budgets that aerospace have available to them are insanely much bigger.

I was recently brought in by a friend as a consultant for a traditional machining shop buying a 3d printer, the machine looked like this: https://i.all3dp.com/workers/images/fit=scale-down,w=1200,gr...

Right now you can print aerospace quality parts on hardware that's designed for marine grade parts, which we did by testing them to failure.

The only reason why the price is higher for aerospace is that you need to certify the machines and the environment in which they work and that costs an arm and a leg.

Are you able to recommend any particular low end machines to have a look at in this space?

Low end here starts at $100k, the machines I was looking at were between 500k and 1m with service contracts.

Or wait a bit longer for a good community design release...

Have fun =3

Just an anecdote: Rocket engineering is the only domain where safety factors <1 are actually ok.

(for some parts)
