It’a detained by magnets so it doesn’t get in the basket and interfere with spreading out the grounds. Needs a clean up with a lick of sandpaper, pretty stupid but these things cost like 50 bucks /shrug
EDIT: appreciate all the concern for my health, it touches dry coffee grounds. I agree that if it got wet there’d be health problems but unless it gets real humid there’s just no opportunity for decay. As for random leaching same diff, without heat and wet it’s not really a concern.
That said I probably will seal an improved design, this is just a test piece.
Why should I? So I get even more combative comments from people that don’t know anything and go “nu uuuh I have done this and I’m fine”?
First of all, I didn’t say “bacteria” only. I said that there is a difference between injection molding food safe plastics, and 3d printing them. The difference is huge in the terms of surface quality, with a 3d prints’ layerlines being a great place for bacteria to form. And you don’t need to put wet stuff into it, to make it form bacteria. Simply put, injection molding makes a uniform surface - by the design of the process, during injection the plastic gets squished to the walls of the mold, with incredible pressure (700kgf on some “hobby” machines, like the Buster Beagle, imagine what a real, few tonne press can do). The process of 3d printing naturally lacks that, leading to a porous end result.
The process of 3d printing introduces contaminates into the plastic. The hotend is basically a huge chemical hazard. Especially if you don’t just print PLA. No amount of cleaning it can change that - burnt bits of plastic, especially on brass, are impossible to remove.
The process of printing also coats the model with tiny particles of plastic that are simply harmful to you when ingested.
Add in the fact, that PLA has other additives that are not food safe, and that you need an actual, certified roll to be “food safe”. Most colorings aren’t that. Most strength additives aren’t that.
Overall there are countless reasons to keep 3d printing away from your kitchen. It’s not “going to be fine”, it’s a health hazard.
I’ll repeat myself for a third time, and stop replying to angry people here - you do you. I wanted to warn people who might not know the risk, who are not in the plastics business. I’m not here to engage in discussions on how to bend health and safety for a project that is not worth it.
