Seems like low data density. I recall some people talking about laser-engraving. IMHO engraving on a solid chemically-inert surface is more likely to be useful.
why not print onto paper and put it in a safety deposit box?
your X/Y resolution isnt going to be fantastic woth filament, but your Z is gonna really suck.
you could instead print(emboss?) like a barcode on some paper, and encase that in resin. the big benefit being that you can read it non-destructively. keep it out of the sun so whatever ink doesnt fade and you're set

You could print an old-school punch card, bring it full circle.
