FDM Foodsafe (lemmy.ml)

So, yes, I know that due to layer lines etc, FDM (PLA) printing isn't safe for food, however is there a way of making it safe? Essentially I want to create a draw insert for cutlery, so can I print it, the coat it in something to make it food safe?

I remember reading something that matches exactly what you're saying above. The material is food-safe, but the geometry is not.

So 3d printing a cup, plate, or measuring cup is not recommended, but the cutlery insert OP is describing should be fine, no need to coat it.
