PETG-CF and health concerns

[vladimir.minkov]

I printed PAHT-CF only once , but since my findings for the other materials and heath issues i got . I realized that have been doing the same thing with ABS and checked a bit how the carbon filter works and the chamber fan on the X1C , so practically it does not for most material will print with chamber fan off and the fumes/other particles will not go through the carbon filter Some suggestions to have it 10% on all the time but that may or may not work for some materials. So the one i liked most is in:

Running Chamber Fan after print to ged rid of bad smell and VOC

I wonder about the Chamber fan functionality during and after printing. I guess, Bambu Lab is using the fan mainly for cooling the chamber during printing with hotter bed temperature and material with lower softening temperature. Nothing against it. What I don’t understand ist, why not run the fan for some time after printing e.g. ABS/ASA to get rid of smell and VOC? Additionally, a small amount e.g. 10-20% won’t hurt during a ABS print.

Create a printer profile and add at end of Machine End G-Code:
; ABS Air filtering
M106 P3 S255 ; turn chamber fan 100%
G4 S300 ; wait 5 minutes
M106 P3 S0 ; turn chamber fan off
Just remember to wait the 5 Min or more:)

That should sort filtering of XXX-CF materials or at least big chunk , also now i found some other people appending a HEPA and bigger filters
The idea i liked is here:

Looking to install exhaust duct to scrub Polycarbonate fumes

I don’t know if you was asking about my setup or lasermike ? But this is what I have on the Bambu lab X1 in my office and for now has been working great with just the chamber fan and big carbon filter I have a few of these setups with fans before they made the 3d air filter systems you can also look into by BOFA 3D PrintPRO 3 fume extraction system.
