As the use of additive manufacturing products (also known as 3D printers) has grown in recent years, concerns have emerged about exposure to airborne chemicals and particles released during the operation of these products, especially in non-industrial spaces like classrooms, offices, and residences. Laboratory tests show that 3D printers emit chemical and particulates into air. In response, UL has expanded the GREENGUARD Certification program, one of the most stringent and well-known product emissions program in the world, to include non-industrial 3D printers.
GREENGUARD Certification evaluates 3D printers to ANSI/UL 2904, the Standard Test Method for Particle and Chemical Emissions for 3D Printers, the first global 3D Printer Standard for minimizing hazardous emissions. Chemical and particulate emissions are evaluated through the use of dynamic environmental chambers and laboratory analytical methods. Products that meet test criteria will receive the UL GREENGUARD Certification Mark and will appear on UL’s SPOT™ product database. UL conducts ongoing evaluations to determine continued compliance with the standard.
UL is a global leader in indoor product emissions evaluations and research, with nearly 30 years of experience identifying more than 13,000 Volatile Organic Compounds (VOCs) and a variety of particulate emissions. Manufacturers who earn UL GREENGUARD Certification for 3D printers demonstrate their products meet the most stringent requirements available and do not contribute to indoor air pollution.
