3DXTech ThermaX™ PEI 9085

ThermaX PEI 3D Printing Filament, Made Using ULTEM 9085 PEI

We manufacture this ultra-performance 3D printing filament using ULTEM 9085 PEI (polyether imide) resin from Sabic. Filaments made from ULTEM 9085 resin offer the ability to create parts with excellent properties at elevated temperatures due to a high glass transition temperature (Tg) of 186°C.

PEI is an amorphous, high-performance polymer which combines excellent thermal properties, exceptional dimensional stability, inherent flame retardancy, and good chemical resistance.

Benefits of PEI 9085 Include:

• High thermal properties, with a Tg of 186°C
• Inherently flame-resistant with low smoke evolution and low smoke toxicity
• Long-term hydrolytic stability
• Excellent dimensional stability, low heat creep sensitivity, and a very low, uniform coefficient of thermal expansion create highly reproducible part-to-part dimensions
• Exceptional strength and modulus, even at elevated temperatures
• Good resistance to a broad range of chemicals, include automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
• Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies

Typical Applications of ULTEM 9085 PEI:

Aerospace:

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:

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

Electronics:

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

Recommended Print Settings:

• Extruder: 350-380°C
• Bed Temp: 140-160°C
• Bed Prep: Nano Polymer Adhesive or 3DXTECH Polyimide Tape
• 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
• Supports: ThermaX HTS High-Temp Support works ideal for complex, high-temp materials just like this.
• Drying Instructions: 120°C for 4 hours.
