    It should be noted that this is not a medical study. It's just a study of nanoparticle emissions of various filaments. As has been said repeatedly once this is brought up, cooking on a stovetop emits higher levels

    Uh yeah, I'm a doc and medical researcher so I realize it's not a medical study, but it is a peer reviewed article in a journal with a fairly respectable impact factor (5.33) published by the American Chemical Society; that being said many of these chemical have been studied in medical studies. For instance if you told me 3D filaments release x parts/million of benzene or mercury I don't need a further study to know that's bad; that's well established. They aren't saying these are at immediately toxic levels, but that these chemical are presents and in what quantity. You can make your own risk assessment

    Hi, dear colleague,
    that's true. The medical and chemical layperson will have limited competence though to judge that crosscorrelation and make a risk assessment - the pure mentioning of nanoparticles will exclude you from some social environments...

    I did not read the study yet, but - far away from FDM - it should be noted that the photopolymers (at least the epoxy-based ones) used in stereolithography are among the strongest cancerogenes. Handling them at home without any protection is a ticket to an unpleasant future. It makes sense to study the impact of all of these derivates of industrial processes in one's private environment diligently and carefully. Thus, I appreciate your pointer to that article very much.

    Interesting. Thanks for sharing. Between my day job of a designer/draftsman in a wood shop, I have breathed in more MDF I can cough out a full board not to mention the lacquer from the paint shop. I'm not worried about the filaments.
    Thanks for the read.

    So that's how they are made? I always suspected something like that... SCNR, hope you understand my pretty black humor... ;)
