Have you tested the grease (or whatever it is) that that plastic heater is using? Is it toxic? Yet we use it. Are neodymium magnets toxic? Yet we use them. Why? Because those are MANAGEABLE risks. That's the same thing I'm suggesting here. Fear mongering and blanket statements are stupid in my opinion. Conversely, just because the filament i use has not caused a problem does not mean another one won't. Same, just because a lot of people have used that heater doesn't mean that some haven't had a problem (tank crashes left and right for a bit there while their QC improved). Making a blanket statement "pigmented PLA is toxic" or "the X heater will bust in smoke, leak grease and kill everything" is completely unacceptable in my opinion. Anyway, i didn't mean this to become an argument, I'm just depositing my experience and thoughts in the matter just like everyone else and name-calling is completely uncalled for in my opinion.
