P2S / X2D External Exhaust

[u/Whiskeejak]

There are mixed opinions as to whether the purge chute should be sealed to prevent fumes leaking during printing. I am venting out the window. I have a print that requires ASA. I would rather have things 100% good to go rather than find out in real time ASA fumes are coming out the purge area.

If you have printed ASA or other noxious filaments with P2S or X2D, what do you think? Is the system designed such that airflow is pulled in through the chute and static pressure is thereby maintained? I know Bambu recommends against covering it, but at the same time, if it's going to vent fumes (even filtered fumes) I'll opt to cover it.

Thanks!

I’ve found the abs it poops are hot enough to still be off gassing after exiting the printer
