3DXSTAT™ ESD-PEEK Properties Include:

• 10^6 to 10^7 ohm surface resistivity on 3DP sample using concentric ring test method
• Consistent surface resistivity and low particulate contamination
• Inherent flame resistance
• Long-term hydrolytic stability - PEEK has an excellent resistance to hydrolysis in boiling water and superheated steam (sterilization/autoclave) at temperatures in excess of 250°C (482°F).
• Excellent dimensional stability (low creep sensitivity and low, uniform coefficient of thermal expansion) and highly reproducible part-to-part dimensions
• Outstanding resistance to a broad range of chemicals, such as automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
• High Thermal Resistance:  Tg of 143°C, Tm of 343°C
• Low smoke and toxic gas emissions

Printing with 3DXSTAT™ ESD-PEEK

PEEK has a melt temperature (Tm) of 343°C, therefore, you will need an all-metal extruder capable of reaching (and holding) temps upwards of 400°C or more depending on your specific printer.  Every printer / slicer is different and you will need to tinker a bit to find a process that works for you.  One of the more difficult aspects of printing with PEEK was getting it to stick to the build plate.  The best material we found was Ultem® PEI sheet or tape.

• Extruder Temps:  375 - 410°C
• Bed Temps:  130 - 150°C
• Bed Prep:  Ultem® PEI tape or sheet
• Nozzle: recommended 0.4mm orifice
• Layer Height:  Ideal layer height is 60% of nozzle diameter
• Please note - PEEK has a tendency to stick to meta
