UL will share its latest research findings on the impact of 3D printing on safety-critical printed part properties and highlight an approach for acceptance of 3D printed materials and components in end products.


Mechanical properties of 3D printed materials have repeatedly been demonstrated to significantly vary based on how test specimens were printed. These variations are substantially greater than for conventional injection molded samples. There is a lack of knowledge, however, on the influence of 3D printing on ignition, flammability and electrical material properties associated with UL safety standards.

  • 3D printing parameters can critically influence material performance properties
  • UL has a process for evaluating materials intended for 3D printing and 3D printed components and products
  • UL can help users interested in 3D printing solve their issues
