What filament/material can be used in the mouth?
Hi,
I'm looking to get a filament that I can use in the mouth. Any ideas?
Thanks
RE: What filament/material can be used in the mouth?
There are a few PET/PETG and PP filaments that are food-grade rated, both FDA and EU.
There are also other considerations when printing, like bed, nozzle, extruder, tube, enviroment etc that might negate the food-safe stamp.
Google: "foodsafe petg filament" and you get some good likns, both adverts and resources. I recommend reading resources first.

Food safe only refers to the material itself. The means of manufacturing (printing) and fabrication (FFF) also ultimately determine if a product is safe. Food safe 3D printing requires stainless steel nozzles (brass contains lead). Consumer-grade FFF printing produces surfaces with many holes to harbor bacteria. Anything you 3D print is likely to be disgusting if not unsafe after a single use.

Thank you both for the information!

While pla and petg are considered (mostly) food safe, the process of 3d printing using fdm (fused filament deposition) creates all kinds of tiny holes where bacteria can house themselves. So it is not really a good idea. Will probably not harm yourself for OWN USE, but don't try to do anything commercial because they'll sue you and you are guaranteed to loose
