UL针对3D打印塑料推出“蓝卡”



UL于4月20日宣布,将推出用于增材制造业的新型塑料鉴定标准(“蓝卡标准”)。这项计划专门针对 3D 打印材料,可认为是 UL 现有塑料认证标准(黄卡标准)的延伸计划。

与传统制造(如注射成型)不同,3D打印过程引入了可变性,会因样本如何被打印,而对产品属性和性能产生显著影响。增材制造的塑料计划定义了识别用于3D打印和3D印刷组件及产品塑料所需的额外要求。

蓝卡计划证明某材料适用于特定的3D打印技术,并有助于确保零组件或终端产品制造商使用经过测试的材料,且该材料的生产也将由独立测试实验室定期监控。

“UL一直通过为增材制造人力开发、设备安全与设备合规性提供解决方案来满足客户需求。”UL研发经理Thomas Fabian博士说:“将蓝卡计划添加到我们的性能材料产品中,展现了UL致力于帮助客户成功应对增材制造领域层层挑战的承诺。”

UL认证的3D打印材料将会添加到UL iQTM 塑料和PROSPECTOR®数据库中。这有助于有意销售其材料是通过UL认证,并可用于 3D 印刷组件材料的塑料制造商,也有助于想要认证 3D 印刷零组件的制造商。此外,蓝卡计划还可满足有兴趣在其设备中使用 3D 印刷零件和组件的终端产品制造商。

The UL Blue Card for Additive Manufacturing

Plastics for Additive Manufacturing

The incredibly fast-growing 3D printing, or Additive Manufacturing (AM) industry, is challenging plastics manufacturers to consider how this technology will impact their market, operations and products. Unlike traditional manufacturing such as injection molding, the 3D printing process introduces a variability which significantly impacts material properties based on how test specimens are printed.

The Plastics for Additive Manufacturing Program (Blue Card Program) is a UL service that enables customers to have published data that facilitates pre-selection of 3D printed materials and components for use in various end products. It defines the requirements necessary to recognize plastics intended for 3D printing, proving the safety, integrity and usefulness of materials.

The UL Blue Card helps ensure that the component or end-product manufacturer is using a tested and certified material, as well as being monitored at regular intervals by an independent test laboratory.

When to use the UL Blue Card Program

The Blue Card Program is to be applied when the material has been processed using one of the following 3D printing technologies:

Material Extrusion

Powder Bed Fusion Systems

VAT Polymerization

Material Jetting

Binder Jetting

Sheet Lamination

Direct Energy Deposition

The Blue Card also includes:

information about the 3D print technology used to process the material;

the 3D printer model designation;

test specimen build parameters specific to the technology (e.g. build plane, raster angle, air gap, etc. for material extrusion technology) and,

multiple safety and performance-related property ratings tested to appropriate standards.

Blue Card vs Yellow Card: The Blue Card differs from the Plastics Recognition Program (Yellow Card Program) in that the Blue Card publishes plastics materials and components intended for 3D printing while the Yellow Card is typically applied for traditional manufacturing technologies such as blow molding, extrusion, film blowing, injection molding rotation molding and vacuum forming.

IMPORTANT NOTE: None of the performance properties/ratings from a UL recognized material (Yellow Card) can be applied, when that material is used in a 3D printing process to print a 3D part.

How to get a UL Blue Card

A Blue Card is automatically issued when a material intended for 3D printing receives a UL Recognized Component Mark. Certified materials are added to the UL iQTM and UL’s Prospector® databases.

Benefits of the UL Blue Card

The UL Blue Card benefits:

Material manufacturers producing materials for use in 3D printed components

Component manufacturers interested in using tested and certified materials to be able to offer certified 3D printed components

End-product manufacturers interested in using tested and certified 3D printed parts and components in their applications

As Material And Component Manufacturers:  Since certified materials are added to the UL iQTM and UL’s Prospector® databases, your Blue Cards are immediately visible to thousands of designers, engineers, and suppliers searching for a material or component provider who meets certain safety and performance requirements.

As End-Product Manufacturers:  Save time and money in the process of seeking certification for end products or systems by using the UL Certified plastics. UL certified plastics are also covered under UL’s Follow-Up Services – a product’s ongoing certification assessment that helps ensure that products continue to meet UL standards of safety and performance.

Boost Product Discoverability – Extend your UL Blue Card with a White Card

Manufacturers can add value by increasing coverage to include the performance properties customers are looking for – all backed up with third-party verification. The White Card, an extension at the bottom of a Blue Card (and Yellow Card), allows manufacturers to promote their product‘s performance credentials to the global markets. It relates to international standards, while the information on the Blue or Yellow Card is typically relevant to North America.
