Why do I have to use all possible different protection equipment (gloves, masks, ventilation and glasses) when printing in resin, but then people put uv resin directly in their fingers? And what about the ones that go in people's mouths? It has to be different right?!

Also didn't even asked about kids TOYS, it wouldn't be a thing if UV resin was so dangerous, right? RIGHT?

Dental stuff has been tested to ensure they're biocompatible, but we still warn team members not to touch unset product even with gloved hands too much. Dentists who have a habit of wiping excess resin on the back of their gloved hands have developed contact dermatitis. Once fully cured, it is unreactive.

Fingernails are pretty inert, so it's not as important. They're still tested to ensure they're not poisonous if ingested, as folks have a tendency to bite their nails.

Exposure time, vapours, biocompatibility, volume - all of these add up to make 3d resin printing pretty hazardous. Even dental 3d printing resins require this level of safe handling, until they're fully cured.
