I'm worried it will impact the cost of filament and printers. Unless there is a cheap way to test and certify filaments. Volumes are still quite low. Regulation risk concentrating filament production into monopolies. Then it will be hard to trust that those certification anyway.

Super valid concern. I imagine it will raise the price considerably and there will be 'safe!' 3d printers that cost a ton because they've been certified and have filaments and suction/vacuum/air pushing systems that have been tested and show no ill effects towards humans. It seems inevitable, but I'd imagine price will come down in a while as things scale.

It also does open the door for someone to come in and make a vent/hood system that works for many types of 3d printers so I guess there's that...
