  • If we could start from scratch, I would define an absolute temperature scale where water freezes at 500, roughly 1.83x the kelvin scale.

    So 4xx is freezing, and the max survivable temperature is around 570. (Water boils at 683, but freezing and boiling can’t both be round numbers on an absolute scale.)







  • It is possible to smooth PLA using ethyl acetate, but I don’t know if that’s good enough for food safety, plus you have to remove the ethyl acetate itself.

    PLA won’t survive in a dishwasher. PETG might, but there are no reasonable solvents for smoothing PETG.

    Maybe it’d be best to print a mold in PLA, smooth with ethyl acetate, clean thoroughly, and then pour silicone into the mold.
