Curious about Inconel as used in the new battery pack connector, I looked it up on Wikipedia, and found that SpaceX has expertise. Thought it is interesting. A cross fertilisation between the two companies. From Wikipedia SpaceX uses inconel in the engine manifold of their Merlin rocket engine which powers the Falcon 9 launch vehicle. In a first for 3D printing, the SpaceX SuperDraco engine that provides launch escape system and propulsive-landing thrust for the Dragon V2 crew-carrying space capsule is fully printed, the first fully printed rocket engine. In particular, the engine combustion chamber is printed of Inconel using a process of direct metal laser sintering, and operates at a chamber pressure of 6,900 kilopascals (1,000 psi) at a very high temperature.
