Man Surely the "Ti" Hopper cannot be turned out of a billet of solid Titanium. Cost to manufacture would be too prohibitive...
I am a machinist for my job and can attest to the beautiful turning work done on this thing. Doesn't it have a 3D-printed heating element as well? It looks good!
I would guess they are using prefabricated Ti tubing as much as possible to minimize machining, then working billet as needed for smaller parts.
3D Printed heating element? That is news to me, although I must say I haven't followed the project that in depth. Wonder what material they used if it is 3D Printed. Anyone have insight on that?
