    More Details


    ULTEM™ 1010 PEI (Now rebranded as Thermax™) Natural 1.75mm 250gms spool.

    ULTEM™ 1010 is a heat resistant, high strength FDM Thermoplastic, created from PEI (Polyether imide) resin.

    PEI is an amorphous, high-performance polymer that combines excellent thermal properties, exceptional dimensional stability, inherent flame retardancy, and good chemical resistance.  Filaments made using ULTEM™ 1010 resin offer the ability to create parts with excellent properties at elevated temperatures due to a high glass transition temperature (Tg) of 217°C. 

    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. 

    Filament Specifications:

    • Diameter:  1.75mm (+/- 0.05mm)
    • Colors:  Natural and Black 

    Recommended Print Conditions:

    • Extruder Temp: 370 - 390°C 
    • Bed Temp: 120 - 160°C
    • Bed Prep: PEI tape is the ideal build surface
    • Print Speed:  Print speeds of 20-30mm/s (starting point), faster as results dictate
    • Enclosure Temp:  Ultem™ 1010 prints best in a warm to hot build environment

    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 3:  After 1 hour at 300°F, increase oven temp to 400°F and allow to stabilize 1 additional hour.  
    Step 4:  After 1 hour at 400°F, reduce heat back to 300°F and allow to stabilize for 30 minutes.  
    Step 5:  After 30 minutes, turn off oven heat and allow printed parts to return to room temp inside the oven as it cools.
