CarbonX™ PEI+CF [Aerospace] Made Using ULTEM 9085 Printing Filament

CarbonX™ CF PEI 9085 Aerospace is made using Sabic Ultem™ 9085 resin and 10% certified Toray T800 chopped carbon fiber. This custom formulation is an excellent printing aerospace-grade material specifically formulated for our aerospace clients.

Ultem™ 9085 is FAA-approved for FST applications (Flame/Smoke/Toxicity) and meets FAR 25.853 and OSU 65/65 standards. Toray T800 carbon fiber has a 5µm diameter (vs. 7µm for standard carbon fiber) and allows for more fibers per cc3 of material than when using standard carbon fiber. This allows for superior strength and stiffness while maintaining excellent dimensional stability and printability.

Benefits of Ultem™ PEI+CF [Aerospace] Include:

  • High thermal properties, Tg of 186°C and an HDT of 165°C
  • Inherent flame resistance due to Ultem™ 9085 base resin
  • Improved stiffness and strength for structural applications
  • Excellent dimensional stability – lower CTE, warp, and shrinkage vs unfilled grades
  • Resistance to a broad range of chemicals, include automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions

ypical Applications of PEI+CF Ultem 9085:


The excellent balance of flame retardancy, low smoke emission, and low smoke toxicity of ULTEM PEI+CF makes it an excellent candidate for aerospace and aircraft applications. ULTEM offers 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:

PEI+CF 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 yet light enough to replace aluminum in others. For applications like transmission components, throttle bodies, ignition components, sensors, and thermostat housings.


PEI+CF 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, FOUPs, BiTS, PCBs, MCCB internals, Plenum devices, LCD projector internals, fuel cell components, and many other applications.

Filament Specifications:

1.75mm and 2.85mm +/- 0.05mm in diameter

Recommended Print Settings:

  • Extruder: 365-390°C
  • Bed Temp: 140-160°C
  • Bed Prep: Nano Polymer Adhesive, 3DXTECH Polyimide Tape, or Ultem PEI tape gives us the best results
  • Other: No cooling fan with print speeds of 16mm/s as a starting point
  • Heated Chamber: Recommended, a chamber helps reduce warping and improves layer adhesion, up to 180°C if equipped
  • Supports: ThermaX HTS High-Temp Support works ideal for complex, high-temp materials just like this.
  • Drying Instructions: 140°C for 4 hours.

ULTEM™ is a registered trademark of Sabic Innovative Plastics





A premier polymer – one of the highest performance thermoplastics ever invented.

PEEK is an ultra-performance filament, ideal for the most demanding functions in Aerospace, Automotive and Electronic applications. This is possible as it has incredible mechanical properties, excellent strength and durability, resistance to corrosion and temperatures, and flame retardancy. It can withstand boiling water and steam.

Printing with this material is very difficult and requires a significant amount of experience in 3D printing. A high quality or heavily modified printer is mandatory.
