I suspect he also means ones where the owners are actually interested in
printing rocket chambers for others and will actually talk seriously
with potential buyers thereof. I expect a lot of the technically
suitable printers are owned by people with other priorities for their
production capacity.

Are you saying all the metal printers in the world can only make about 468 5k thrust chambers per year? I disagree.

It’s a fairly quick bit of math to find that the launch rate of
an expendable system with printed thrust chambers ends up being
constrained by the total number of printers in existence in the
world (and really, by the number of printers you can use within
the artificial constraints of it*r).
That number is about one rocket’s worth of chambers per week.
Distributed across the four or five significantly capitalized
companies that are doing printed thrust chambers.

With high value payloads perhaps. That seems like an expensive
logistics operation added to small and expensive launch
system. Just an opinion but perhaps focusing on designing and
producing an inexpensive, simple and reliable booster in
vehicles this size and forgoing recovery would make more sense
from an operational cost standpoint. Or perhaps not. A few
successful missions should confirm it either way.

Electron is going to try it and it's something that's been
done in the past.

It is a topic about which I don't know enough even to be

If there is such a person on this list, and you are
interested, I can
pass on this guy's email.
