Material Overview

Considered an engineering grade Fused Deposition Modeling (FDM) thermoplastic, ULTEM 9085 is renowned for its high strength-to-weight ratio and flame-retardant properties. This material is a polyetherimide blend, offering superior mechanical performance and ease of printing, making it ideal for demanding engineering applications.

Mechanical Properties

ULTEM 9085 offers exceptional strength-to-weight ratio. Despite being lightweight, it possesses remarkable mechanical properties, making it ideal for applications where strength and durability are critical. This attribute enables engineers and manufacturers to design and produce components that can withstand rigorous conditions without compromising on performance.

Chemical Compatibility

ULTEM 9085 demonstrates excellent resistance to a wide range of chemicals, including automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions. This chemical compatibility ensures its reliability in harsh environments, where exposure to aggressive substances is common.

Thermal Properties

It stands out for its high glass transition temperature, around 186°C, enabling it to maintain structural integrity and mechanical properties at elevated temperatures. This thermal resistance makes it an excellent choice for applications involving heat exposure. ULTEM 9085 is certified UL94 V-0. This certification ensures that the material meets stringent standards for fire safety. In scenarios where fire resistance is crucial, ULTEM 9085 provides peace of mind by exhibiting exceptional flame retardancy properties, minimizing the spread of flames, smoke generation, and toxic emissions.


ULTEM 9085 finds applications in various high-performance fields, such as aerospace, automotive, and military industries. It is commonly used for functional prototypes, production parts, and thermal insulation components, where its combination of strength, thermal stability, and chemical resistance is crucial.


ULTEM 9085 also offers documented traceability, which is a critical feature for industries requiring stringent quality control and compliance. Forge Labs, a company that utilizes ULTEM 9085 in their processes, benefits from the assurance of traceability, which allows them to track and verify the origin and quality of the material used in their high-performance functional applications.
