Has anyone tried screen printing on PLA and/or PETG?
T-Shirt ink requires high heat to cure the ink, so is there a special kind of silk screen ink that cures with UV or air-dry?
I want to screen print the lettering on this model:

I’m guessing you don’t have an AMS and can’t just print the lettering? Since the lettering appears to be on the top surface, you could reasonably do manual filament swaps to garner the same results.
All of the shirt inks I’m familiar with are heat cured, so I don’t have any suggestions for that, but I can maybe suggest a different method. You can create a 3d printed stencil of the lettering you want on the model and then use a paint marker to mark the lettering.
I do have an AMS, but that lettering would look so much better with stenciled letters - much more realistic.
There are acrylic screenprinting inks (and really, any thick acrylic will work as long as your workspace isn’t bone dry).
There are also UV set/UVCure screenprinting inks, but I have no experience with them. The downside is that you need to work indoors with good ventilation, and make absolutely positive that you completely remove any ink you get on your skin (or you will suffer as soon as you get into sunlight or near a UV lamp). https://www.nazdar.com/en-us/Find-Your-Screen-Ink might be useful, and https://www.nazdar.com/en-us/SCREEN-INKS-Inks-By-Chemistry-UV-Curable-Inks
