ULTEM™ 9085 Resin

ULTEM™ 9085 Resin | specified FDM Thermoplastic

Technical Overview

ULTEM™ 9085 resin is a specified PEI (polyetherimide) thermoplastic, renowned for its unique combination of mechanical, thermal, and chemical properties when processed using FDM® technology. Its primary differentiator is the ability to produce lightweight components with high strength that are also certified for flame, smoke, and toxicity (FST) documentation review, making it a leading material choice for regulated industries.

Mechanical and Thermal Performance

This material provides an excellent strength-to-weight ratio, enabling the production of defined yet lightweight parts. ULTEM™ 9085 resin also exhibits high thermal stability, with a heat deflection temperature of up to 178 °C (353 °F). This ensures that components maintain their dimensional accuracy and structural integrity when operating in demanding, high-temperature environments.

Flame, Smoke, & Toxicity (FST) documentation review

Safety and documentation review are critical in public transport and aerospace applications. ULTEM™ 9085 resin is inherently flame-retardant and has been certified to meet stringent industry standards for flame, smoke, and toxicity. These certifications include FAR 25.853 for aerospace and the EN 45545-2 standard for railway applications, ensuring parts are suitable for use in passenger-facing environments.

Chemical and Electrical Resistance

ULTEM™ 9085 resin demonstrates outstanding resistance to a wide array of chemicals, including automotive fluids, hydrocarbons, alcohols, and aqueous solutions. This resilience prevents material degradation upon exposure, ensuring long-term part reliability. Additionally, its high dielectric strength makes it an effective electrical insulator for applications such as housings and electronic enclosures.

Design and Processing Guidelines

ULTEM™ 9085 resin is designed for compatibility with Stratasys Fortus and F900 series industrial 3D printers. It prints with SUP8500B™ soluble support material, which allows for the creation of complex geometries and internal features with a simple, hands-free post-processing workflow. For optimal results, high-temperature build sheets are required.

Lifecycle: From Prototype to Production

The certified properties and reliable performance of ULTEM™ 9085 resin make it suitable for the entire product lifecycle. It is used to create functional prototypes that accurately simulate the performance of the final product and is extensively qualified for manufacturing durable, flight-certified end-use parts, tooling, jigs, and fixtures.
