UL publishes impartial review on 3D printed polymer properties


Global security certification business, UL, has printed an unbiased analyze on the outcomes of 3D printing certification on polymer qualities. The benefits of the examine have been applied to build a framework to qualify resources for safety-vital industrial factors. The Illinois-dependent organization hopes the framework will support people today and organizations across the AM supply chain in mitigating the threats connected with 3D printing certification beforehand uncertified resources.

Blue Card certification

UL’s impartial research explored the flammability, ignition, and electrical properties of polymer sections fabricated making use of 3D printing certification. These 3D printed areas were being when compared to identical pieces produced employing standard injection molding. The UL scientists saw major versions in security and overall performance across their comparisons and concluded that performance scores used with common manufacturing strategies can’t be applied when the exact part manufactured from the identical content is 3D printed.

The UL workforce then took to developing a certification method for 3D printable polymers, the Blue Card. The info necessary for a maker to guarantee the integrity and efficacy of a 3D printable material is introduced on the material’s Blue Card. A Blue Card is immediately issued when a 3D printable content is capable by UL, obtaining a UL Recognized Element Mark.

The Product iQ database

A record of AM materials certified by UL can be identified in UL’s publicly obtainable database, Merchandise iQ. Producers are capable to search by the databases at any time to find certified 3D printable products suited for their respective programs. By using a trustworthy third-party tested and certified content, end-use ingredient suppliers preserve on time and expenditures when certifying their finish-use goods and units. In addition, as Blue Cards are specific to a 3D printer, equipment makers have the alternative to certify a materials for express use on their individual programs.

UL’s white paper,Certifying plastics for additive production certification’, delivers an overview of the exploration results. The finer specifics of the independent examine can be observed in UL’s research paper, ‘Affect of 3D Printing certification on Protection-Vital Polymer General performance Properties’.

Material certification is critical if a presented product is to be applied for protection-important industrial applications, earning the course of action a aim for several organizations concerned in the AM provide chain globally. A person these types of group is certification corporation Aspect, who recently upgraded its laboratory in Huntington Beach, California with a committed characterization facility exclusively for AM powders. Elsewhere, TÜV SÜD, a main technological company corporation, has made a new certification program for steel AM powder companies to confirm the high quality of their processes. The system was successfully tested and validated with a pilot audit of Rosswag Engineering, a steel processing enterprise primarily based in Germany.
