About the CarbonX™ Carbon Fiber Ultem® 3D Printing Filament
Manufactured in the USA by 3DXTech, CarbonX™ Carbon Fiber Reinforced Ultem® 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® resin offers the ability to create parts with excellent properties at elevated temperatures due to a high glass transition temperature (Tg) of 217°C. The addition of high-modulus carbon fiber greatly increases the stiffness / modulus of the material as well as reducing dimensional instability often seen with unfilled materials.
Product attributes include:
- High thermal properties: (Tg) of 217°C
- Inherent flame resistance
- Long-term hydrolytic stability
- Excellent dimensional stability (low creep sensitivity and low, uniform coefficient of thermal expansion) and highly reproducible part-to-part dimensions
- Exceptional strength and modulus, even at elevated temperatures
- Good resistance to a broad range of chemicals, such as automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
- Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies
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.

Annealing Printed Parts: If needed, parts printed using Ultem® PEI 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.
