Honestly, instead of all that, the general rule should be don't use 3d printed stuff with food, period. Cause everyones focused on what can leech into the plastic and cause nastiness, but no one focuses about what could leech out of the plastic. Especially in this era where every month theres some new recall of some product that has something terrible in it that shouldnt be there.
and even if you do manage to find and buy a filament that claims its food safe/food grade, your printer is not. The materials used in 3d printers are not food safe, the lubricants and greases are not food safe, the previous filaments that you've printed with and have left buildup isnt food safe, and theres probably a lot in the average printers hot end that is not food safe.. Not to mention the bed, and any adhesives you might use.
Its just not worth the risk to yourself or potential loved ones, So don't even try it in all honesty.
3d printers are great, fantastic even. Mines saved a lot of money by letting me design and build replacement parts and tools to do obscure jobs specific to the situation, and even some pretty nice gifts and other stuff. Its great at a lot of things.
but it will never be good for anything to do with human consumption. Don't let 3d printed materials touch your food, drinks, or be involved in prep areas.
