Last fall, Boston-based 3D printing company RIZE, Inc. announced with pride that its RIZE One 3D printer was the first in the world to receive UL 2904 GREENGUARD certification. Now, the company has successfully expanded its portfolio of GREENGUARD certified products, including the XRIZE full-color 3D printer, RIZIUM ST filament and RIZIUM inks.

The UL GREENGUARD certification is based on the ANSI/CAN/UL 2904, “Standard Method for Testing and Assessing Particle and Chemical Emissions from 3D Printers,” which itself was the result of an extensive investigation into the emission of volatile organic compounds (VOCs) by desktop 3D printers and their potential health hazards. Products with the UL GREENGUARD label have been rigorously tested against third-party chemical emissions standards and have demonstrated their ability to minimize the risk of air pollution and chemical exposure for 3D printer operators.

“GREENGUARD Certification is rigorous for a reason – because indoor 3D printing use has long been an industry issue,” explained Alberto Uggetti, Vice President and General Manager for UL’s environment and sustainability division. “As the first 3D printer, material and ink to earn GREENGUARD Certification, RIZE demonstrates its leadership and commitment to providing healthier indoor environments. We congratulate them on yet another sustainability and safety accomplishment.”

The XRIZE is now the first full-color composite 3D printer to receive a UL certification for low emissions and safe usage. RIZIUM ST and the RIZIUM inks series, for their part, are also the first 3D printing materials to receive the certification. The XRIZE 3D printing system uses both materials to create parts: the RIZIUM ST filament is used to build up the part in question, while the colorful inks are subsequently jetted to dye the part as it is built. The filament (based on olefin materials) is specifically developed for the process and has low moisture absorption and high temperature resistance.

“GREENGUARD Certification is the gold standard for 3D printing health and safety, and we’re delighted that RIZE’s materials-first approach to 3D printing is getting recognized by scientific leaders as well as major manufacturers,” said Andy Kalambi, CEO of RIZE. “Our RIZIUM Alliance and continued commitment to materials innovation is enabling manufacturers, product designers and any 3D printing user to create adaptive workflows that drive safer, sustainable 3D printing and propel the next generation of advanced manufacturing.”
