About metal, until we have big simpson to play with, maybe sandmold is what we can sidestep with current design: [youtu.be]
If 3/6 arms Simpson can do accurate aluminum milling, I think it is enough to be game changer.
Updated : There's a technique to cut very tough metal without physical cutting force called EDM, but I didn't know how it really works. [fab.cba.mit.edu] from [mtm.cba.mit.edu]
Or very slow and precise micromachining end mill with turbine, possible ?
