ANSI/CAN/UL 2904, "Standard Method for Testing and Assessing Particle and Chemical Emissions from 3D Printers", addresses the emissions from 3D printers commonly found in non-industrial indoor environments like schools, offices, and homes. This standard provides a method for testing and assessing particle and chemical emissions from these machines. As 3D printing becomes more integrated into workplaces, studies have highlighted the potential health risks associated with exposure to ultrafine particles and volatile organic compounds emitted during printing. This standard offers important protocols for measuring and mitigating breathable emissions, supporting safer practices in indoor spaces.
As the use of industrial-scale 3D printers continues to grow across various industries, understanding the emissions generated during the printing process is becoming increasingly important. Recent observations have revealed that these printers can produce high concentrations of nanoparticles in the breathing zone of workers nearby. The concentration and size of these particles depend on factors such as the feedstock used and may vary by printer model. Given the potential health hazards associated with exposure to these emissions, it is essential to implement proper ventilation around and inside 3D printers to mitigate risks to worker health.
Monitoring particle number concentrations in the vicinity of these devices is crucial to identifying and addressing inadequate ventilation. TSI's Engine Exhaust Particle Sizer™ (EEPS™) spectrometer serves as an ideal instrument for this task, offering accurate measurements of particle concentration and size at high time resolution, making it well-suited for the dynamic environment of 3D printing. This application note will delve into the methodologies and findings related to assessing 3D printer emissions, providing valuable insights for ensuring worker safety in the evolving landscape of additive manufacturing.
