Went to the AM show in Birmingham, and it's all maturing nicely whilst still keeping the new tech buzz. I was interested to see a couple of demo pieces printed in tungsten. JOEL selectively fuse the powder bed with an electron beam, which is what you would expected from an electron microscopy company. Melting tungsten is impressive because of its enormously high melting temperature. Mind you, they use a 6kW beam to do it!

I have to say that I fail to see what would be the inherent advantages for the industry here. I have looked a bit but it passed way over me. So might be something more DIY.

It's accepted by many that the best value production method, especially in volume, is anything but 3D printing. Having said that, for low volumes the elimination of tooling costs can swing the cost balance, but the real trick is to redesign parts to consolidate many parts into a much smaller number of parts. Some companies are reducing 150 parts down to 20 odd, and the elimination of fastners and welding/glueing yields a lighter part.
The really excitemant comes when you can 3D print something that you just can't make any other way, and top of the list are things with internal cooling passageways. At a 3D printing show two years ago I saw a sectioned rocket nozzle printed in Inconel with the most intricate cooling passageways in the bell where they presumably pump fuel as a coolant to stop the whole thing melting. There's no way you could make that any other way.

Ah yes, 3D printing is a valuable tool. No doubt.
But an Autogenous modeler... Why?
