3DXSTAT™

ESD-Safe PEI 3D Filament 

MADE USING ULTEM™ PEI

Shipment : NOW IN STOCK

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.

  • 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)

Surface conductivity as a function of extruder temperature:

esd-pei-ultem-resistance.png

The surface resistance of the printed ESD-safe part will vary depending on the printer's extruder temperature.  For example, if your testing indicates the part is too insulative, then increasing the extruder temperature will result in improved conductivity.  Therefore, the surface resistance can be 'dialed-in' by adjusting the extruder temperature up or down depending on the reading you receive on your part. 

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) 
  • Drying Instructions:  Please see the following instructions for when you want to dry out this filament.

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.
