The emission levels during the printing process differ significantly between Acrylonitrile Butadiene Styrene (ABS) and Polylactic Acid (PLA) filaments. ABS generally releases a higher quantity of volatile organic compounds (VOCs) and ultra-fine particles (UFPs) compared to PLA. These emissions can include styrene, a known irritant, and other potentially harmful chemicals. In contrast, PLA, derived from renewable resources like corn starch, tends to produce fewer and less hazardous emissions.
Understanding the disparity in emission levels is crucial for ensuring safe and healthy operating conditions, particularly in enclosed or poorly ventilated spaces. The concentration of emitted particles can influence indoor air quality and potentially pose respiratory or other health concerns. Historically, the awareness of these emissions has grown alongside the increasing popularity of 3D printing technology, prompting research into safer filament alternatives and improved ventilation strategies.
