UL’s plastics experts conducted a systematic, independent research study investigating the influence of various 3D printing and build parameters on safety-critical performance properties, especially those defined in UL 94 and UL 746A. Results were also compared to properties measured on injection molded specimens.
This research led to the creation of UL’s certification program for Plastics for Additive Manufacturing (Blue Card). The Blue Card program defines the requirements necessary to recognize the safety and suitability of plastics intended for 3D printing and 3D printed products. UL’s program independently certifies this critical information for the AM industry.
- Findings explained on the effects of 3D printing on critical material performance such as ignition, flammability and dielectric strength
- Understanding how to apply pre-selection of materials for faster product compliance evaluation
- The Blue Card explained - UL’s new certification program for Plastics for Additive Manufacturing
- Certifying 3D printed products and components
