Health risks associated with home 3D printing

Home 3D printers can release ultrafine particles and volatile organic compounds (VOCs) into the air, even when no visible smoke is present. During filament heating, these emissions can penetrate deep into the respiratory system. While PLA filament is often considered a less problematic alternative to ABS due to lower particle production, it is not entirely harmless; studies have indicated signs of inflammation and cellular stress in respiratory cells exposed to both materials.

Resin printers require additional precautions. According to the National Institute for Occupational Safety and Health (NIOSH), uncured resin can cause skin irritation and respiratory issues, including asthma. The washing and curing processes also pose risks, particularly when solvents are used.

To minimize exposure, it is recommended to operate 3D printers in independent rooms, workshops, or garages equipped with adequate ventilation and external air extraction.
