Nothing major just been thinking of trying to make a butter dish, maybe some measuring cups so started to do a little research and this is what I have found:
1. PETG is considered to be food safe for the most part but for that extra piece of mind you can find PETG that has been certified food safe.
2. Don't use brass nozzles due to the risk they can leach lead into the print.
3. The layer lines provide places for bacteria to grow.
It seems like using a non plated steel nozzle paired with PETG would get you 90% of the way to a safe print. What I want to know is if I have overlooked something or are there is any other precautions I could take. Perhaps reduce layer height to produce a finer surface that while there would be more layers there would be less space for crud to inhabit? and would hand washing be enough to clean the print completely after use.
