Paramount PDS (Langhorne, PA), a product development and rapid manufacturing company, is using PA 2210 FR material from EOS (Novi, MI) for rapid manufacturing of commercial aircraft components. PA 2210 FR is the first flame-retardant polyamide for SLS (selective laser sintering) systems. The material has passed independent testing for aircraft burn, smoke, toxicity, and UL 94 V-0 flammability.

The material is used in the rapid manufacturing of more than a dozen flight hardware components for commercial luxury aircraft.

Jim Williams, president of Paramount, says, “Laser-sintering with PA 2210 FR has enabled this aircraft company to slash production lead times and eliminated tooling costs. Our customer has qualified and adopted laser-sintering for production of custom polymer flight hardware.”

Williams also notes that his customer has leveraged the freedom of design that rapid manufacturing offers. “Each aircraft component was specifically designed and engineered for rapid manufacturing,” he said. “This resulted in complex configurations, which could not be molded or machined, that addressed the form and functional needs of the aircraft hardware application.”

Because Paramount PDS had customers that required flame-retardant materials, it became a beta test site for PA 2210 FR.  The material is now commercially available worldwide. PA 2210 FR complies with flammability and smoke generation regulations—FAR 25.853; ABD 0031/AITM 2.0002, 2.0007; and BSS 7230/7238—and smoke toxicity—ABD 0031/AITM 3.0005; BSS 7239. PA 2210 FR also has a UL 94 V-0 flammability rating and is free of halogens.
