Interesting.  I've never noticed much issue from that (but I've only printed a spool or two of glowing stuff)

It depends to some extent on the exact GITD material. The blue-green glow usually uses strontium aluminate which is quite abrasive. Other colors use zinc or (i think) calcium compounds and aren't as problematic but also don't glow as well. The size and quantity of the particles matters and that varies by manufacturer.
