This has definitely been discussed here before; if you're worried, it's generally agreed that PLA fumes/particles are much safer.

- amenghra 11y agoMy understanding is that PLA safety has been established at ambient temperature (and it is safe). Consequences of exposure to heated PLA is still an unknown. Personally, I would only use 3D printers in well ventilated areas. I would also not eat from 3D printed food utensils, even though some of the stuff people have designed look fabulous.
- Palomides 11y agothere are plenty of good reasons not to eat off of 3D printed materials (impossibility of cleaning/sterilizing them properly), fear about the properties changing due to heating the PLA seems weird since any plastic you interact with has almost certainly been heated at some point. by the time you're inhaling these particles, they're not going to be much (if at all) warmer than room temperature.
