UL's independent research investigated the safety-critical performance properties of 3D printed samples against injection-molded samples. Researchers identified significant variations and concluded that performance ratings from traditional manufacturing techniques cannot be applied when the same material is used in 3D printing.

The findings have been used to develop an independent program for evaluating and qualifying plastics intended for 3D printing, helping AM stakeholders mitigate risk and deliver quality and performance.

Primary Topics:

  • Effects of 3D printing on ignition, flammability, and dielectric strength
  • Applying pre-selection of materials for faster product compliance
  • The Blue Card explained – plastics used for additive manufacturing
  • Certifying 3D-printed products and components
