- Steltek 5y agoI don't think switching to PETG is an automatic win? You still have a rough, porous surface that can trap bacteria. I stay away from food-related prints but I thought the best method was to print in whatever reasonable material you want and then coat it in something food grade, like resin. Then you get the material and print properties of PLA, PETG, whatever but food safe.
