Boston-based 3D printer manufacturerRize宣布已获得UL 2904 GreenGuard认证RizeOne 3D printer和细丝。该认证是基于UL 2904Standard Method for Testing and Assessing Particle and Chemical Emissions from 3D Printerspublished by the Illinois-based global safety consulting and certification firmULin 2018.具有UL 2904 GreenGuard认证资格的产品被科学地证明可以遵守严格的第三方化学排放标准。
Rizeis said to be the first company in the 3D printing industry to have received the certification. Alberto Uggetti, vice president and general manager for UL’s Environment division comments, “As the first 3D printer provider to earn GREENGUARD Certification to UL 2904, RIZE demonstrates their leadership in proactively bringing 3D printers to market that help support healthier indoor environments. We congratulate them on this notable accomplishment.”
UL2904 GreenGuard认证
在2018年，UL和Georgia Institute of Technology, published一个two-year study详细介绍从许多台式3D打印机中释放出的挥发性有机化合物（VOC）和超细颗粒（UFP）。雷电竞app下载这些排放是已知的健康危害，因此向学校，医院，办公室和工厂中的3D打印机包围的人带来了健康风险。雷电竞app下载
Over 90 percent of the UFPs emitted by the 3D printers are said to be less than 0.1 micron in size. Their nanoparticle dimensions means that, when inhaled, they can cause cardiovascular and pulmonary issues. Furthermore, the study also found that there are more than 200 VOCs produced by 3D printers, many of which are identified irritants and carcinogens. Common VOCs detected include formaldehyde, a known carcinogen, and caprolactam, a known irritant of eyes, nose and throat that can also cause headaches.
As a result of the study, UL had identified the need to create emissions standards for the rapidly growing 3D printing industry, and published theUL 2904Standard Method for Testing and Assessing Particle and Chemical Emissions from 3D Printers。这standard outlines the particle and VOC emission limits of 3D printers, therefore demonstrating that the machines can effectively operate without having a negative impact on indoor air quality.
GREENGUARD资格
这UL 2904GREENGUARD资格for “non-industrial” 3D printers is part of the GREENGUARD certification program by UL for test methods, standards and emission limits encompassing a variety of product groups. These groups include building materials, furniture and furnishings, electronic equipment (3D printers fall within this category), cleaning and maintenance products, and medical devices for breathing gas pathways. Products that have received the GREENGUARD certification are deemed helpful towards reducing indoor air pollution and the risk of chemical exposure, while also enabling the establishment of healthier indoor environments.
这RizeOne is the first 3D printer to be certified with the UL 2904 GREENGUARD certification. The system was commercially introduced by RIZE in 2017, and was marketed towards use within indoor office environments upon its release. Geared towards the production of functional prototypes, tooling and service parts, the system uses the company’s proprietary增强聚合物沉积(APD) technology which combines extrusion and ink jetting simultaneously to build 3D parts. It also features a 300mm x 200mm x 150mm build size, and requires minimal post-processing for its completed components.
“We are delighted and honored to be the first company with products that achieved the UL 2904 GREENGUARD Certification,” explained Andy Kalambi, president and CEO of RIZE, Inc. “Safety and sustainability is at the core of our mission to expand the usage of industrial 3D printing to all users and in all workplaces.”
“We were able to meet the requirements set forth by UL 2904 because we purpose-built the RIZE system for safety and environmental-friendliness, with our engineering-grade thermoplastic compounds that are best-in-class for strength, yet safe to use virtually anywhere without special venting, disposal equipment or gloves.”
Setting standards for safety in 3D printing
UL first published the “Standard Method for Testing and Assessing Particle and Chemical Emissions from 3D Printers” in January 2019. The first edition of the document,ANSI/CAN/UL 2904, is intended to be used by stakeholders seeking to mitigate indoor air pollution risks from 3D printer emissions.
Additionally, UL has published anOutline of Investigation for Additive Manufacturing Facility Safety Management。这UL 3400文件certifies operations for handling both polymer and metal powdered feedstock. Leading defense companyLockheed Martinwas the first to achieve theUL 3400 certification for additive manufacturing。
Furthermore, UL has also launched aBlue Card for additive manufacturing materials program。该程序允许客户发布数据，以促进3D打印材料和组件的预选，以用于各种最终产品。
