UL Blue Card Plastics for Additive Manufacturing

Certifying that your plastics materials are appropriate for use in 3D printing. Once recognized, your products will be searchable to thousands of suppliers looking for a material that can meet their safety and performance requirements.

UL’s Blue Card surrounded by plastic materials.


The incredibly fast-growing 3D printing — or Additive Manufacturing — 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 new level of variability. These inconsistencies can significantly impact material properties based on how your test specimens are printed.

Our Plastics for Additive Manufacturing Program (Blue Card Program) provides you with data that facilitates preselection of 3D printed materials and components for use in various end products. It defines the requirements necessary to recognize plastics intended for 3D printing, helping prove the safety, integrity and usefulness of those materials.

Essentially, our Blue Card Program provides third-party certification that you are using a tested and certified material and that your materials are being monitored at regular intervals to ensure ongoing compliance.  

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
  • 3D printer model designation
  • Test specimen build-parameters that are specific to the technology, e.g., build plane, raster angle, air gap, etc.
  • Multiple safety- and performance-related property ratings tested to appropriate standards
Blue Card versus Yellow Card

The Blue Card differs from the Plastics Recognition Program (Yellow Card) in that the Blue Card publishes plastics materials and components intended for use in 3D printing. 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.

    Boost product discoverability – Extend your Blue Card with a White Card

    You can add additional value to your Blue Card by increasing coverage to include the performance properties that your international customers are looking for. The White Card, an extension at the bottom of a Blue Card and Yellow Card, relates to global standards, as opposed to those typically relevant in North America. Receiving a White Card enables you to promote your product‘s performance credentials to the world — giving you the opportunity to reach more markets than ever before.

    Who benefits from the UL Blue Card?

    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 that can meet certain safety and performance requirements.

    End-product manufacturers  Our certified plastics services were designed to save you time and money during the certification process and our Follow-Up Services (FUS) help ensure that your products continue to meet our Standards for safety and performance.

    Why UL

    UL is a leading global provider for the production of test specimens, and testing and certification services for innovative plastics.

    We have been testing plastics since 1941 and are proud to serve all of the world’s top plastics manufacturers. We work closely with plastic industry stakeholders to maintain and enhance existing UL Standards, establish new Standards, and develop certification and testing programs that address emerging technologies and product applications.

    We are uniquely positioned to provide a complete view of how your products will function within a given system. This is particularly critical in the plastics and components industry. Interactions between substances, parts, systems and the environment can be the cause of a significant number of hazards and failures, which are rarely apparent when components are tested individually.

    Most importantly, we support your drive to protect public safety and brand value by mitigating your risk with quality assurance and supply chain compliance services. Our trustworthy reputation provides an important product differentiator in a crowded marketplace, communicating safety and quality to original equipment manufacturers (OEMs), purchasers and regulatory authorities.
