I’ve heard of a few trying to copy the process and the challenge beyond materials is improving yield enough to be profitable. It’s a savagely complex and cut throat business model that really would require deep pockets for quite a long time.Barriers to entry too great, regulations. I spent some time looking into this a couple years ago with the thought of creating tube company in the US. The regulations make it simply undoable, which I believe is why they’re made in China, Russia and Slovakia. But I didn’t get too deep before giving up, maybe there is a way with some deep pockets and could afford to lose money for a while.
