Hi all, I’m sharing a project I’m working on - it’s a high performance 2 stage air filter.
I find that even the smell of PLA gets annoying if the print time exceeds 30 minutes.
It removes the OEM carbon filter with a much larger (thus less restrictive and more efficient due to lower air velocity) carbon stage and a large HEPA filter stage.
These are pics of the second prototype - the airflow seems plenty good (I don’t have numbers), gotta test out whether the sniff-o-meter gives a lower VOC reading with more testing.
The main body part didn’t print too clean, gotta find a way to fix that too.
Your work looks very cool, but why hold it with tape?
Aren’t those holes in the back of the printer for use screws in?
I received my P1S last week and I also have to think of a way to put an extraction sleeve on it.
The smell doesn’t bother me, especially because I’m only using PLA Basic and honestly I still haven’t been able to smell anything. The problem may be in what we don’t see.
Hey some of the holes aren’t tapped and people have tapped them to use them, and for the other holes - you need to find longer screws to use there, etc so I wanted to keep it simple.
However, not all back panels are flat and the tape can lift off over time because of that.
This recirculating filter does a LOT more at filtering the smells and particles though:
Why not installing (ok its pricy) a second Aux fan? so you can use the left one for the print and the right one for filtration? like a bento box with fans
I always design for easy printing on all printers, if a design needs an aux fan, it’s a bad design for FDM imo. Almost all other popular models I’ve seen also follow this principle. So naturally, I don’t use the aux fan as it causes more problems than it solves.
Using the aux fan for filtering means the filter is controlled by the slicer - it will turn on auto when the print starts, and turn off auto when the print is done - it’s nice!
But I understand it’s not for everyone, and there are other solutions already.
