Fume extraction to outdoors - how to connect?
Hi,
I'm very seriously considering getting a Core one L . I would actually prefer to wait to get one pre-built with an INDX (assuming that wil happen) but that might take too long. The printer would be setup in my (rather small) shed (about 2x3 meters) and to keep my wife happy (and me healthy) I want to make sure that particle and voc concentrations are kept low.
I think the best way to achieve this would be to extract the air from the printer's chamber and vent that outside of the shed. I have the following questions about this:
- How and where would I connect a flexible pipe to the backside of the printer where presummably there are two exhaust fans?
The distance between the backside of the printer and the wall where the pipe exits would be less than 2 meters. - For some filaments the built-in exhaust fans apparently won't be on (or at least not all the time). To prevent particles and voc's escaping there would have to be constant underpressure in the 3d printer's chamber. How can I make this work in pratice?
- For other filaments the vent at the top is opened automatically. Will the built-in exhaust fans always be on when the top vent is open so that air is draw into the 3d printer's chamber through that top vent? Again this would be necessary in order to maintain underpressure.
- Should I have a fan at the end of the flexible tube where it exits the shed? How would this interfere with what the printer is doing in terms of chamber temperature management?
I guess my question could be summarized as follows: How can I make external fume extraction through the back work well in all scenarios (top vent open/closed, back fans on/off)?
The simple alternative would be to install a fan fume extractor to ventilate the entire shed but that would not be as effective as a proper underpressure->direct extraction solution. I also do not want to rely on active carbon filters; the sort that would be used with something like this would probably contain too little carbon to be truly effective. I have some proper carbon filters for use in our home and those contain close to 2kg of carbon each.
Thanks for any advice or suggestions from the Netherlands.
