I previously discussed 3D printing air quality issues and mitigation approaches here and here. In this post, I’d like to highlight another informative resource—a YouTube video by Jonathan Levi whose screen name is The Next Layer. His video is called “I was DEAD WRONG about air quality” and can be viewed here:
He admits that he is not a scientist, and he also acknowledges that his video is sponsored by a company that makes a featured air circulation unit. That being said, his semi-scientific methods led him to some insightful conclusions. First of all, air filtration is an important approach to improving air quality, but air circulation (room ventilation) are just as important, and a multi-pronged approach may be needed to purify air in 3D printing workspaces. He also noted that despite a combination of filtration and circulation, it often took a long time (e.g., sometimes overnight) to bring air quality back to normal. He also pointed out that outside air can have its own impurities—namely particular matter—depending on where you live. But the impurities of outside air are likely to be particular matter and less likely to be volatile organic compounds, so air circulation would still likely be highly beneficial.
Check out the links in his video description for other informative resources.
