A Bambu Lab P1S is $600, and then you gotta buy PET-CF filament, and there's shipping consider as well, so let's say ballpark $800 to start. They make more expensive printers too if you have the budget for it, but the underlying technology is mostly the same. Filament comes in 1kg rolls, and small stuff is like 50 grams, but a large piece of pipe including support structure could be as much as 500g, so if you end up printing a large amount of large items, eg https://makerworld.com/models/1441653 instead of https://makerworld.com/models/77668, which is 2g, and cheaper PLA, filament costs are going to add up.
