I’m intrigued by the technology, but can someone tell me the advantages of 3D printing over other methods of producing the same parts? I understand the conceptual advancements, but what about cost per item, time to produce, percentage of defective parts, etc.?
They can make a part that may be equal or a little lighter/thinner walled but stronger than the same part that is milled. Also if you can make sections together instead of separate parts less leaks and gasket issues, less dissimilar metals issues, less thermal expansion and conraction issues.
I remember talking with some of the older engineers and they told a story of how GE picked core technologies to focus on during the 1960s. Some are represented by the core-businesses today - ie electric, power, aviation, locomotives ... One of the areas they mentioned was supercomputers. They said they even had their own operating system. If I remember correctly, they said GE eventually sold the division to Honeywell. I found tht rather fascinating!
Thanks. That makes total sense.
That's quite a lot of risk - and only ONE engine. If it fails, you're walking (you hope).
GECOS if I correctly recall. GE Comprehensive Operating System. Yes, sold to Honeywell.

The PC12 is a very popular single turboprop aircraft. It uses advanced monitoring to make sure the engine is in good shape. I can’t recall any accidents related to engine failure.
Twin engines can actually be less safe.
“If your engine doesn’t work, there you are - if your brakes don’t work, where are you?” doesn't apply to airplanes.
