This 3D-printing stuff is getting cooler each and every day. Engineers at GE Aviation’s Additive Development Center in Cincinnati effectively cooked-up a 3D printed engine comprised of 3D printed parts that are able to rev up to 33, 000 RPM. INCREDIBLE.
This miniature jet engine is the same type of engine you can find in RC model planes.
It’s a lot simpler than the engines which power modern jets. A commercial aircraft engine is entirely too complex for their working model which is why they had plans for the simpler model.
“We wanted to see if we could build a little engine that runs almost entirely out of additive manufacturing parts,” says one of the engineers. “This was a fun side project.”
