Anybody else wired up by the latest additive manufactured Nasa engine?
Also, Nasa has been doing some 3d printing in space but today it's only plastic extrusion.
How about metals? We are pretty advanced on this tech on earth (like this breadboard engine) but on the ISS it doesn't seem to be in the pipe on shorterm
what are the complications that would make it hard to do in space?
I suppose the layering of metal wouldn't work in microgravity?

So for practical reasons, the powder layer would probably be unpractical, it would fly on all directions. But that can be compensated if the aparatus rotates on itself at a high enough speed to create some kind of microgravity that would maintain the powder in place through centrifuge force.
Now the finishing of the part might prove trickier, see the vid.
