Printing ABS inside living spaces
I am in process of building a filter for my CoreOne from what is available on Printables. I was planning to go with the Vento, seems fast and easy. But I am concerned with printing in my living spaces as despite CoreOne's enclosed designs I see wide gaps in the corners, with the fans running I don't feel much air being pushed and wonder if it is acceptable to print ABS and other VOC/FP filaments inside with just a filtration system. My printer is in my small workshop converted from a bedroom that is 9'x7' inside the main living space of my house. I don't see any good a filter on the back of the fans is going to do with all the airgaps in the corners and door does not form a solid airtight seal. I would like to print ABS and ASA and probably PCCF which I bought the hardened nozzle for.

The gaps in the enclosure are not the problem, I'd say. As long as some air is actively pushed out through the filter by one or more fans, there will be airflow into the enclosure through the gaps, and no significant amount of particles or VOCs should escape there.
But you will not be able to push enough air through a HEPA + carbon filter with just the built-in chamber fans of the Core One, or with another fan like this one. Those ventilators are not meant to push air through a path that offers a resistance to the airflow. You will need a different type of fan, like the radial blower used in Prusa's own filtration option, to force air through the filter.

I print it with my Core One and barely smell it.

RE: Printing ABS inside living spaces
Thank you, that is what I suspected the chassis fans were not enough to push air through the filters. I get my best option is to buy the Prusa CoreOne filtration system. Currently it is backorder 5-7 weeks. I am still a bit concerned about the air gaps in the corners, I know some air as to come to let air out, but I guess I can tape the rear corners. I am concerned about VOC from abs or other filaments. I plan on just buying the Prusa filtration system.
