I'd like to print a mouse shell from food safe PLA.
I need it to be food safe, because sweat can dissolve any harmful chemical from it just like foods. I am not sure about how to finish it after sanding the result. I read that people use food safe epoxy to seal it before painting to get a smooth surface. I read that others seal it after painting to cover the paint, which is possibly not food safe.
So I am not sure if I should seal it before or after painting or maybe both? I read that some people use shellac or even nail polish instead of epoxy to get something that they think is food safe. So the entire topic is starting to get somewhat chaotic for me. What materials should I use for sealing and painting and in which order?
