There is a caveat, but yes: By definition, 3D printed parts should not be considered food safe.
Single-use cookie cutters are generally OK if you don’t use them multiple times a day every day.
There are probably minor chemical risks but it wouldn’t be in high enough quantities to kill you. There isn’t really anything inherently food unsafe with PLA, ABS or PETG.
Bacteria is a much bigger risk during reuse because you can’t fully clean the prints between the layer lines and other surface defects. The plastic generally won’t survive a proper sanitization process either.
What your own risk tolerance is for plastic additives is up to you. If you do print a cookie cutter, toss it after you are done.
I really don’t condone producing single-use 3D prints unless it results in a net reduction of plastic waste for the same end. It would make more sense to 3D print a form to turn a thin strip of steel into a proper food safe and reusable cookie cutter. No waste and you can make as many cookie cutters as you want.
Some tea bag brands are really proud that they’ve moved from petroleum based plastic on their bags to PLA.
What the fuck. It’s still plastic, guys. There are a few brands that don’t have any plastic. You have to look them up brand by brand though.
I’m not super paranoid about plastic, but I have been trying to avoid it a little more. And the biggest place to avoid it is soaking it in near boiling water that I’m about to drink.

Also this is a cookie cutter. Usually you bake after which should kill anything the cookie cutter may have left behind.
You can’t kill plastic by baking, you just turn it into even worse stuff
Oh you are thinking of plastic going into the food, normally hear people talk about bacteria growing on it.

Isn’t PLA made from plants though? Then just dispose of it properly how would that be an issue.
