We offer cost-competitive prototype and low-volume production 3D printed parts made using Ultem® PEI and a wide array of ESD-safe materials. Ultem® offers exceptional thermal, chemical, and mechanical properties - making it the ideal material for the most demanding applications. More Info
Ultem® 9085 PEI (Polyether Imide) is an amorphous, high-performance polymer that combines excellent thermal properties, exceptional dimensional stability, inherent flame retardancy, and good chemical resistance. Ultem® 9085 resin offers the ability to create parts with excellent properties at elevated temperatures due to a high glass transition temperature (Tg) of 186°C.
Product attributes include:
Aerospace Applications: The excellent balance of flame retardancy, low smoke emission, and low smoke toxicity of Ultem® 9085 makes it an excellent candidate for aerospace and aircraft applications. Ultem® 9085 meets FAR 25.853 and OSU 65/65 with low toxicity, smoke and flame evolution. Ultem® resins are found in applications, such as personal service units, oxygen panels and components, ventilation system components, connectors, cable ducts, latches, hinges, food tray containers, door handles, and interior cladding parts.
Automotive / Transportation Applications: Ultem® resins provide automotive manufacturers with a high performance, chemically resistant, thermally-stable, cost-effective alternative to metal that is strong enough to replace steel in some applications and light enough to replace aluminum in others. For applications like transmission components, throttle bodies, ignition components, sensors and thermostat housings,
Electrical / Electronics Applications: Ultem® resin may be an excellent material choice for today’s demanding electrical applications, including connectors, MCB components like housings, shafts and levers, hard disk drive internals, FOUP’s, BiTS, PCB’s, MCCB internals, Plenum devices, LCD projector internals, fuel cell components and many other applications.
Recommended Print Conditions:
Annealing Printed Parts: If needed, parts printed using Ultem® may be annealed in a hot-air oven to reduce any printed-in stresses that may be present in the part. Printed-in stresses may occur in any plastic and may result in lower than expected mechanical properties. If this is an issue with your part, then you can follow the simple 5-step ramp up/down process for annealing the Ultem® parts.
Step 1: Place printed parts in cool, room-temp oven.
Step 2. Set temp to 300°F and allow to stabilize for 1 hour.
Step 2: After 1 hour at 300°F, increase oven temp to 400°F and allow to stabilize 1 additional hour.
Step 3: After 1 hour at 400°F, reduce heat back to 300°F and allow to stabilize for 30 minutes.
Step 4: After 30 minutes, turn off oven heat and allow printed parts to return to room temp inside the oven as it cools.

Ultem 9085 has a lower glass transition temperature than 1010, and this results in prints being much easier to perform. Printing in an enclosure is still essential (airflow will prematurely cool layers and decrease layer adhesion), but printing in a heated chamber is best.
Good results were achieved at 340C - layers bonded completely and the part was nearly as hard as a 1010 part. Small parts can be printed on glue, but Kapton tape as recommended is likely safer and less likely to warp.
One quality that sets polyetherimide apart from other materials is its great fatigue resistance; it is stiff, but will not break when flexed. Accordingly, printed parts are extremely hard, but are more similar to polycarbonate in their ductility than PLA. Of course, Ultem 9085 is also incredibly strong and, unlike nylons, extremely hard.
This material is quite expensive, but if you need a material that prints nicely and makes no compromises for mechanical properties, it's worth giving 9085 a try.
