It's printed from Bambu PLA Pure. That's a filament for food contact: its five ingredients are each tested against EU Regulation 10/2011, plus EN 71-3 and UL GREENGUARD. What's tested is the material, not our printer, which is why we put it this way and not as a seal.
The manufacturer names two limits itself, and we pass them on: no liquids, because the grooves between the layers are too coarse for that, and nothing above 60 degrees. For dry coffee grounds, for a few seconds, neither is an issue. On top of that, we print the part at 0.12 mm instead of the usual 0.2 mm, so the grooves are shallower.
