Hi, in all the z-materials of the title seems that the fumes “can” be dangerous. i’ve the M300 dual with the filtering device.
is the filtering “enough” or do I have to vent further the room?
Thanks in advance

Hi! Thanks for your questions. Generally, most filaments from reputable manufacturers and trusted sources are safe for 3D printing. However, good ventilation is essential. A HEPA+carbon filter can remove up to 99% of harmful particles, but keep in mind that printers aren’t completely sealed, so trace amounts of emissions may still be released. I use a custom enclosure with a HEPA+carbon filtration system (the red components in my setup) and a soundproof seal. I also monitor VOC and TVOC levels with a sensor to ensure safe printing conditions. I don’t use a HEPA cover filter, as it wasn’t sufficient for my needs.
Here’s a list of potentially harmful substances emitted by common filaments:
| Filament | Hazardous Substances |
|---|---|
| ABS | Styrene, Formaldehyde, Phenol, Acetone, Toluene, Ethylbenzene |
| PLA | Formaldehyde, Acetaldehyde, Ultrafine Particles (UFP) |
| HIPS | Styrene, Formaldehyde, Phenol |
| PC-ABS | Styrene, Formaldehyde, Phenol, 1-Butanol |
| Nylon | Caprolactone, Acetaldehyde, Ultrafine Particles (UFP) |
| ASA | Styrene, Formaldehyde |
| PETG/PET | Formaldehyde, Acetaldehyde |
| PC (Polycarbonate) | Bisphenol-A (BPA), Formaldehyde |
I’ve attached images of my printing enclosure for reference. From my research, the filters I use are effective. The Zortrax cover alone wasn’t enough for my setup. I also monitor all indoor parameters using a Tuya air sensor.
Feel free to ask if you have more questions!
