Rize achieves UL 2904 GREENGUARD certification with RIZE One 3D printer

Rize Inc., Concord, Mass., has announced it has become the first in the 3D printing industry to receive UL 2904 GREENGUARD Certification with its RIZE One™ industrial 3D printer, as well as its Rizium ™ One filament, Release, and Marking inks. This certification is based on the new UL 2904 Method for Testing and Assessing Particle and Chemical Emissions from 3D Printers.

A two-year study published by UL and the Georgia Institute of Technology found that many desktop 3D printers release VOCs and ultrafine particles that are known health hazards into the air. More than 90 percent of the particles emitted by these 3D printers are in nanoparticle range and, when inhaled, can cause cardiovascular and pulmonary issues. More alarming in the study is that there are more than 200 VOCs detected, and many are known irritants and carcinogens. In 2018 UL published emissions standard UL 2904 for 3D printers that outlines particle and VOC emissions limits to demonstrate that 3D printers can be used without negatively impacting indoor air quality.
