3d printed shoes are… almost a thing(1). Clothes, not so much… some experimental high fashion fabrics, but nothing you’d wear under normal circumstances.

But to your point about PFAS, afaik no common 3d printing materials contain PFAS - at least not filament ones, i don’t know much about the resin printing world.

The only place PFAS is used in an FDM printer is the filament guide some printers have. That's a Teflon tube that the filament travels in towards the hotend. Bowden style printers tend to have a long tube, direct drive printers sometimes have a short tube fully contained in the hotend assembly.

I don't see how PFAS can be used as a filament in FDM printer. It's not a thermoplastic, that's one of its advantages as a material.
