It sounds like the issue is particulates rather than gasses; in that case an activated carbon filter won't do much and a HEPA filter would be better.

- esskay 4y agoWith all the new materials that you can get I think a combination of both (plus venting to outside) is needed for real protection. The current hot new printer is the Bambu Lab X1. It's aimed at consumers and is capable of printing things like Carbon Fiber Nylon, Polycarbonate and Thermoplastic polyurethane (TPU). These are far more volatile than run of the mill PLA and theres less studies available on their long term effects so take as many precautions as possible should be the message.
- tdeck 4y agoFor sure. Many of these materials aren't new on the 3D printing scene either (even I've printed TPU on my $180 delta printer). For most hobbyists PLA is the vast majority of their print time and it's a shame that we don't even have convenient and affordable systems to mitigate the risks of the baseline material (I don't consider cobbling together your own enclosure, ducting, and filter system convenient. As we have seen with open frame laser engravers, most consumers won't bother).
