Yes but common sense is also there for a reason, I would absolutely trust this material to handle very light duty tasks like this. There is a difference between following rules within the boundaries of common sense and spouting them off in any tangentially related scenario without having done any testing yourself or even seeing the product in action. There is simply no way to definitively say "this is a bad idea" without doing microbe tests and comparing it to baseline levels after a period. I think people tend to jump on the not food safe bandwagon a little too readily in this community and I'd rather not see this place become like an average reddit hobby ground
I'd quadruple upvote this if I could.
Or - and this seems to have escaped your analysis - in this case we’re talking about health and safety rules and rules dealing with food preparation. Not exactly the kind of rules you want to be gambling with. But sure. It’s a feee world, do what you want. But I still wouldn’t want to be using this with my coffee.
And you're free not to, just don't bash others for choosing to do so
Yeah there is a way to say "this is a bad idea" without microbes tests. This is a bad idea, plain and simple. Just because you want to say otherwise, doesn't mean you are right. It's simply not food safe.
Oh you're being a wowser.
So food safe is a phrase averaging a series of concepts. I agree it is tremendously unwise to say eat soup repeatedly out of a 3d printed bowl because of inability to clean it properly and leaching of contaminates.
It's probably not very dangerous to eat peanuts once out of a 3d printed bowl because there's no liquid to leech shit through and you're not relying on washing it.
you need to think about the underlying mechanisms of things. If you don't know anything then abundant caution is wise, but you should probably couple it with humility.
Leeching through solids is the only real concern here and I probably get orders of magnitude more heavy metals from my tap water (which are still safe limits) or VOCs from the plastic decaying slowly in the soil that grows my veggies (all soil on earth is contaminated at this point, but I grow next to farmers and lemme tell ya nobody hates the environment like farmers).
Chill out about your microbes already. The world is full of them and other micro-organisms that don't harm you.
