Concerns about air quality during 3D printing are increasingly common, particularly regarding the safety of inhaling fumes from melted plastic. A recent experiment aimed to quantify these effects by monitoring air quality while using a 3D printer.
Experiment Setup
The experiment utilized a household air quality monitor, specifically the Vindstyrka from IKEA, which measures the volatile organic compound (VOC) index and particulate matter (PM2.5). The monitor was placed near a Bambu Lab P2S, an enclosed 3D printer equipped with an activated carbon filter. The printer was situated in a small bedroom, typically used for guests.
To ensure accurate readings, the experiment was conducted without typical ventilation measures, such as using a ceiling fan or opening a window. The printer was operated using PLA, a biodegradable filament derived from plants, which is generally considered safe but can release contaminants when heated.
Observations During Printing
The print job, which lasted just over four hours and consumed approximately 175g of filament, provided valuable data on air quality. The monitor showed that while PM2.5 levels remained stable, the VOC index experienced a significant spike, peaking at 248 during the print. After the print concluded and ventilation was introduced, the VOC levels dropped sharply.
Throughout the experiment, the monitor also recorded VOC spikes during other common activities, such as cooking and using cleaning products, indicating that various household activities contribute to air quality fluctuations.
Conclusions Drawn
The results suggest that even with an enclosed printer like the P2S, VOC levels can increase during printing. This finding emphasizes the importance of proper ventilation when operating 3D printers, as well as during cooking and cleaning. The data collected during the print highlighted the necessity of maintaining airflow in the room to mitigate potential exposure to harmful airborne contaminants.
In light of these findings, the author plans to enhance ventilation by using a fan attachment for the printer to direct fumes outside. This experiment underscores the need for awareness regarding air quality in environments where 3D printing occurs.
