Do I have to sand or is there some magic I’m not aware of?

    Thanks!

    Everything I found said that cured resin is inert. I did see that there are biocompatible resins out there but they seem to be mostly used in dental applications. I’ll keep searching though.

      IIRC, cured resin is not as toxic as uncured, but it is in no way “inert”. Piercing locations are typically soft tissue, and therefore more susceptible to contact issues. Please, be safe, and if you’re selling these: ensure your clients are, too. To put this in perspective: would you feel as confident in this “inert” state were you printing binkies for infants?

        @Piecemakers3Dprints @CaptainFlintlockFinn as a one time chemist I’d agree that there is a real possibility some trace materials in the resin causing some harm in prolonged contact. The resin may be set but could potentially leach some of the other materials such as unreacted ingredients, catalysts etc. In the same way that cheap jewellery can release alloying metals that cause irritation. A dermatologically safe varnish seems a sensible call.
