What food-safe printing materials do you use?
I just use PLA. PLA itself is good safe, but occasionally the additives aren't, so I don't use any for human related stuff. It's also worth considering that the layered approach can allow for bacterial growth, so unless you treat it (e.g. epoxy seal it), you'll need to wash it fairly frequently to curb buildup.
That frequent washing is what leaks out the nasty chemicals from the plastic fyi. Heat and mechanical stress are the main way plastics leach
To be fair, that's the case with pretty much all plastics.
Tupperware shouldn't be used to reheat food in the microwave for the same reason, yet that's it's most common use generally.
Untreated PLA is more brittle than commercial food-safe plastics though, that is true.
