PLA resin biocompatibility
Hi fellows,
This is my first post here. I'm using a Phrozen Sonic Mini 4K 3D printer and I'm looking for resins which can be used in the mouth. The usual and safe bet is to use surgical guides resin which is surely biocompatible. But I recently realized that PLA bio-based resins claim to be safe. This is an example about what I mean:

This resin is even certified as EN71-3 (European toy standard):
https://www.intertek.com/toys-childr...mical-testing/
This certification means the material will not release toxic elements even if it's swallowed. Despite this certification could make this resin usable it's not marketed for that use. Is this related to its biocompatibility or is related to its mechanical properties?
I don't need exactly the same mechanical properties of surgical guides, so if biocompatibility is similar I would test this resin.
Thank you very much in advance!
