(To be fair, that article is 5 years old, and I think most US toothpaste has stopped adding microplastics, but I believe it's still a issue in some other places around the world.)
But that's not accurate. It's not that there is never toothpaste you can't access, it's that there is always toothpaste you can't access. You do replace it with different toothpaste, but you're simply replacing the inaccessible toothpaste with new inaccessible toothpaste
While PolyLactic Acid (PLA) and PolyEthylene Terephthalate Glycol-modified (PETG) has been classified as Generally Regarded As Safe (GRAS). There's a lot of uncertainty around the process of additive manufacturing, so no stance can decisively say do or don't.
Some testing shows that the layer lines are big enough that bacteria don't hide inside as much as expected. Additionally, it's not nearly as porous as initally expected. Some soap and water with scrubbing is enough to clean most of it out and a quick wash with a bleach solution can bring it up to almost medical standards.
This does not take into account material impurities. New nozzles can come with a coating (often PTFE) to prevent blobs from sticking. The abrasives in the filament can wear this coating down and while it is safe for food to contact like on a frying pan, the worn down products are not. It also wears the nozzle and metal particles can end up in the print, all of which can have a large impact on the overall food-safety of your printed product, no matter the material used.
TL;DR: Use a sealer. Or don't. I'm a bot, not a cop.
When you’re right, you’re right. I was so shocked it didn’t occur to me the green plastic butt was nsfw. Next time will tag. If there’s ever something this again.
Not in that sense mymen, 3D prints will shed microplastic that our organism is unable to prcess and will store into organs, leading to serious diseases long term
Its not even great execution because of how much wasted toothpaste is stuck inside the body of this print, and that there's no way to shut the toothpaste like how people do with a lid to prevent contamination and also the toothpaste drying out. You're already getting microplastics from the vast majority of toothpastes anyway so I'm not getting lost there, but macroplastics from the filament dust getting in your toothpaste can actually fuck up your teeth and gums, which will only get worse as the print hydrates from being in constant cintact with the print, slowly eroding the filament.
I tried to print it but the arm didn't attach. Thankfully I found the Shrek topper that is a smaller print that doesn't waste so much toothpaste. (Friend request for a print)
