Emissions will be mitigated via the radon vent system pipe located nearby.

That’s a good idea. Would never have thought to tap a line into my underslab system. Are you worried about reducing the vacuum pull?

Not 100% sure yet. I oversized my fan a bit when I built the system , so sb ok. But regardless, I think I just need positive ventilation and to have a path for the fumes to go. It does not seem like a lot of vapor is coming from my pla prints, so the volume of air introduced will be small and should be acceptable. No clue on abs or nylon prints yet, but I cant see 3d printing materials outgassing too much. The manometer on the rafon vent tube will tell me if the negative pressure is maintained. If that works I will find a 12 or 24 volt butterfly valve and let the printer turn the vent on.

But for now need to finish the base.
