The results of this study actually presents that PLA fumes are more toxic than ABS fumes.
In practice though, the study shows PLA is safer because of significantly less fume creation with the lower printing temperature.
So relative risk for PLA is significantly lower than ABS, but it is incorrect to state that PLA is less toxic.

It's effective down to a fraction of parts per trillion for certain chemicals. https://en.wikipedia.org/wiki/Odor_detection_threshold#Odor_detection_value https://en.wikipedia.org/wiki/Odor_detection_threshold#Odor_...

- LarryMullins 4y agoYou can't count on your nose to warn you, but when your nose does warn you it pays to heed that warning. If your nose is screaming at you to GTFO, listen to it. You listen to your other senses, right? When you touch something hot, you listen to your sense of touch telling you that you're about to get burned. That doesn't mean your sense of touch can warn you of all hazards, but you certainly shouldn't ignore it when it does.
- Fomite 4y agoThat's my usual line when people talk about smell being indicative of how safe something is. Farts smell. Carbon monoxide doesn't.
