I suppose you could print filament of arbitrary length by doing batches that get pieced together.
Here's my best idea so far how to do it:
(1) Instead of a spiral, print in a double spiral. Meaning a spiral that starts on the outside, goes to the middle, makes a u-turn, and then goes out to the edge again. (For the u-turn, I assume filament has some minimum turn radius and as long as you stay above that, it's workable to straighten it out.)
(2) Pause printing, put a clamp over one end of the printed filament, yank the rest off the bed and wind it on a reel.
(3) Resume printing, and repeat as many times as necessary.
