Do you have to prime 3d printed objects? If not, just print the number and like dip into water paint. Ideally you could print a lip with higher numbers so only the top of the numbers get painted

If it’s bevelled text you can swap filament during print to make it stand out / easy to read.
Only problem is that you have to baby sit the print, which could slow down production considerably

Heat stamping might be quickest alternative. Should be rugged and aid low-vision use.
Full brass letterpress type sets and die can be pricy, but the cheap leather iron kits at craft shops commonly include small metal alphanumeric types that could be set (clamped) and affixed to your stamp (burning/soldering iron or pliers + hot plate/stove).
