Printing with PETG

[ralphzoontjens]

Yes most PETT and PETG filaments are food-safe as is PLA. Look for grading for this specific brand as they still may contain some volatiles.
And it's best making sure you deburr the part well of course. With 0.10 layer thickness you have the best chances of it being watertight as well.

I've been surprised in the past at how easily prints were watertight, but it occurs to me that water might get trapped inside a print. Is going with 100% infill a good idea? Bad idea?
