ULTEMTM 9085 is a polyetherimide (PEI) thermoplastic that is getting a lot of attention. It is one of the most popular FDM (fused deposition modeling) printing materials in manufacturing. What are the reasons? Let's look at the benefits that this thermoplastic brings and its various applications.

Why 3D-Print Parts with ULTEM 9085?

A Material with Unique Properties

ULTEM 9085 has many specificities. As a matter of fact, it is a high-performance, flame-retardant thermoplastic. It offers a high strength-to-weight ratio, excellent resistance to heat, chemicals, and impact. This thermoplastic is also FST FAR25.853 certified for flame, smoke, and toxicity standards.

Another important fact is that the ULTEM 9085 resin meets rigorous test criteria and retains the traceability required by the aerospace industry. The analysis certificates document test results, and pairs the lot numbers of the raw material with the filament. This allows full traceability from the printed part to the raw material.

ULTEM 9085 and FDM 3D Printing: Multiple Applications

Due to its properties and its high quality, ULTEM 9085 is a highly south-after resin in the aeronautics, aerospace and automotive sectors. This material is used both to produce low-volume end-use parts, functional prototypes or tooling.

For example, ULTEM 9085 can be used for the FDM printing of components intended for the interior of aircraft, such as various types of ducting. ULTEM 9085 can also be used for prototype for high-demand applications and specialized tooling such as jigs, fixtures or lightweight high-strength composite molds.

Reduce the Cost of Parts by Opting for 3D FDM Technology (trademark of Stratasys)

According to common practice, the industry generally manufactures thermoplastic parts through 3D printers defined as “open”. Although this technology has proven itself, it does have certain limitations. In fact, some materials such as ULTEM, by their properties, can be difficult to print. The parts produced can then display an exorbitant price. Opting for Stratasys' FDM 3D printing technology makes it possible to counter these problems and ensure the success of your projects. As a result, printed parts are generally priced competitively for higher-end materials.

Solaxis has a selection of Stratasys FDM printers, one of the largest in the country. Thus, our team of engineers can support you in developing and designing thermoplastic parts with complex geometries, and this, by combining short manufacturing times, large production capacity and competitive prices.
