Thermoplastic resin deployed in aerospace application via additive manufacturing


An amorphous thermoplastic polyetherimide (PEI) grade has been designed for application in rapid prototyping for small runs of parts. Ultem 9085 addresses one of the biggest challenges for aerospace OEMs according to its developer SABIC’s Innovative Plastics business (Pittsfield, MA): namely to produce small volume parts quickly and cost-effectively.

The strong, lightweight, flame-retardant resin has been utilized together with Fused Deposition Modeling (FDM) technology from Stratasys, Inc. (minneapolis, MN), to enable a Stratasys’ customer, Taylor-Deal Aviation LLC (TDA; based in Dallas, TX), to create specialty fluid and air handling parts in hours rather than weeks, while meeting the latest industry regulations for flame, smoke and toxicity.

Key benefits of this unique new use of Ultem 9085 resin with FDM include enhanced design flexibility, cost-effective low production runs, accelerated cycle times and compliance with the Federal Aviation Administration (FAA) and OEM flame-smoke-toxicity regulations....
