ESD-Safe PEI 3D Filament

3DXTECH produces this 3D printing filament using a specialty compound custom-formulated using ULTEM™ PEI resin and advanced carbon additives.  PEI is an amorphous, high-performance polymer that combines excellent mechanical, thermal, and chemical resistance properties. Our PEI based filaments offer the ability to create parts with excellent properties at elevated temperatures due to a very high glass transition temperature (Tg).  Ideal for use in critical applications that require electrostatic discharge (ESD) protection, a high level of cleanliness, and the outstanding thermal and chemical properties you've come to expect with PEI based compounds.  

Product attributes include:

  • 10^6 to 10^7 ohm surface resistivity on 3DP sample using concentric ring test method
  • Consistent surface resistivity
  • Low particulate contamination
  • High thermal properties
  • 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

Typical applications include:

  • Semi-con / Electronics:  HDD Components, Wafer Handling, Jigs, Casings, & Connectors 
  • Industrial:  Conveying, Metering, and Sensing applications

Filament Specifications:

  • Diameter:  1.75mm (+/- 0.05mm)
  • Color:  Black 

Recommended Print Conditions:

  • Extruder Temp: 360 - 390°C (all-metal extruder)
  • Bed Temp: 140 - 160°C
  • Bed Prep: PEI tape (ideal); or Polyimide Tape, Lightly sanded FR4 or Perf board.
  • Other:  No cooling fan, Print speeds of 1000mm/min (starting point) 

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