Damn man. Thanks for sharing that. Hope you are okay now. This is exactly why I do not print ABS, ASA… even though some people are taking this matter so lightly… as if they do not care at all.
Also, very much related (it is about toxicity of Bambus PETG-CF): PETG-CF and health concerns
We need more stories like this and things that happened to people. Please, do not hide if you have health issues due to printing. This area is so under investigated. I think only community can help each other by telling what happened or how you feel. I have expressed my concerns regarding PETG-CF in above link. You see no health related warnings from manufacturers regarding any filament but ABS and ASA. As if everything else is safe to print. But I am sure it is not like that.
I am wondering about legality of whole matter. Usually, states control dangerous chemicals, objects,… so that people do not end up sick or dead. Especially when it comes to buying freely available commercial products. Here, we see companies selling obviously dangerous materials that can put you in hospital, but it is completely unregulated - they do not even have to put a warning label on it. I am almost certain that there will be cases of people suing these companies for selling dangerous stuff without warnings. It is just a matter of time.
