Pretty cool. I use to build rockets models all the time, I mean like constantly doing all kinds of experiments then fell out of it. I use to make rockets that would take off and disappear they went so high lol lol. You would just see the smoke trail and that was it. Oh yeah then the ones you could see they parachute would deploy and they fall like 10 miles away, could never get them, they were cool as hell though, I could never get enough of them.

Could be a game changer. Regenerative cooling is still the best way to get large masses into orbit, and will be for quite a while.

The brazed "spaghetti" nozzles that make it work are really, really expensive.

Using 3D printing to make those nozzles should have a substantial price impact.

I read that ATK is working on a 3D printed engine too. I think they've flown an engine with 3D printed parts, but not a whole engine.

This is what happens when you raise the minimum wage to 15 bucks an hour.

3 parts? So they don’t count pumps, valves, regulators, and igniters as engine parts?

3-D Printer Ping!

Some day her prints will come…

You could sear a steak pretty good under that engine.

My ancient knowledge of 3D printing was the old UV cured epoxy models we would get made for fit checks of the eventual machined part. Brittle as heck, with lots of lines on the surface from the cured layers. No good for anything other than something to fondle as a solid part.

Printing is quite different now it would seem.
