I think the play would be to get one that’s modular (I suspect it’s been done) and just keep building it out. The trick would be if the Earth is flat enough of it to sit nicely on. If not, you could cheat by slightly changing the DPI further from the center, so it would be a sphere section.
Ok, now where can we get a printer to print that?
a global network of printers
A national network will suffice.
