food grade?
Is any of the PLA Prusa sells food grade ("FDA approved")? (Or any material Prusa sells?)
Re: food grade?
I don't think so but here's an American vendor who sells FDA approved PLA: https://www.makergeeks.com/collections/dishwasher-safe

Do not forget that FDM technology cannot produce food grade parts since there will always be some gap between the layers where nasty bacterias can grow.

I wasn't planning on using them as containers, but things like cookie cutters or pots for (editble) plants. I saw that it's possible to coat them with polyurethane, will look into that.
Just some minutes ago I found this too: https://shop.prusa3d.com/en/filament/94-xt-black-filament-750g.html which seems to be foodsafe. So I guess it was just extra hard to find and I can answer my own question...?

Re: food grade?
Yes, I planned on switching nozzle but that requires it's own research.
I expected Prusa to be ROHS compliant though, so it shouldn't contain lead?
Re: food grade?
The stainless steel nozzle is food safe and medical grade. Also a lot of PLAs and PETGs. But as LaPointe said FDM is not food safe.
Re: food grade?
Not a lawyer but I have read up on this subject from various places. There are just too many factors to be in any way "food safe" by definition for 3D printers.
As mentioned earlier you have the layer gaps that can host bacteria/other particles. The actual extruder must in some way be clean. The filament needs to be clean. The nozzle needs to be clean. The heat break needs to be clean. The bed must be clean. That probably doesn't cover all the factors.
The alternative I have heard to get around this is to somehow silicone seal your prints after the fact but I'm not sure how well that works. One thing I deal with at my work is primary packaging of pharmaceuticals and we have specifically maintained and tested clean rooms. I'm not sure if that's necessarily a requirement for food safe but something else to consider.
Most people trust a one time use of food safe plastics but again that's a risk you have to determine. I'm not looking to try food safe at any point just due to all the complexities.
Re: food grade?
Food safe enough for personal use is probably Doable. Might want to look into sealers.
Food safe enough for something to sell. Not here in the litigious US.
