Certified food-grade PETG + food safe resin seal is the best from what I have read (I researched a bunch as I am building a greenhouse)

    Thank you for the knowledge! It looks like foodgrade petg is 3 times the price and I don't plan on changing nozzles and stuff to keep everything kosher anyway. So I reckon I'll use regular petg and hit it with Shellac for the redux. Unless you have a food safe resin seal to recommend based off your research?

    Thanks again!

    Hobby woodworker here. Shellac is great for an initial seal, but isn't waterproof. I suggest using a two part epoxy instead. You don't need a very thick coat, so you could even use a crack filler and/or self leveling variety.

    No problem - yeah that will probably be just fine, at non-commercial scale the seal will probably never get worn off and if you did ever notice spotting you can just reseal.

    Nope not yet! Still in the structural phase here so when I get to printing I will share for sure.
