If I remember correctly, Airbus also said recently they've found that they can 3D-print parts that are lighter, cheaper, faster to produce and require less energy to produce.
And SpaceX and NASA are 3D-printing rocket combustion chambers. The chamber pressures are lower than rifles, but have to be sustained for seconds to minutes at time. Not sure how they'd compare to pressures in a howitzer.
PSI is a fascinating subject. Honda makes their own CVT, I noticed nissan and the others outsource their CVTs.
