there 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.
