3DXSTAT™ ESD PPS 3D Filament
ESD PPS (Polyphenylene Sulfide) is an electro-static discharge (ESD) safe formulation of PPS, a high-performance polymer which exhibits exceptional chemical resistance along with high thermal and mechanical properties. Widely known as one of the most chemically resistant thermoplastic materials available.
ESD PPS is completely insoluble in any known solvent under 200°C.
ESD PPS is used in some of the most demanding applications in Auto, Chemical Processing, Oil & Gas, and Electronics. It is inherently flame retardant and self extinguishing, making it an ideal material for electrical and electronics applications.

Target Conductivity for 3DXSTAT™ ESD PPS:
- 10^7 to 10^9 ohm surface resistivity on 3DP sample using concentric ring test method.
- Note: Internal studies have indicated that increased extruder temperatures can achieve higher levels of conductivity. Likewise, lower extruder temperatures have resulted in lower levels of conductivity. Each printer is set-up differently as well as varied part geometry. Therefore, expect some trial time to understand how this filament works in your specific printer / application. However, please do not exceed 270°C to reduce the risk of polymer degradation.
Surface Conductivity as a Function of Extruder Temperature:
The surface resistance of the printed ESD PPS 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.

Annealing (Post-Crystalizing) 3D Printed PPS Parts:
Parts printed with PPS must be annealed after printing to ramp-up the crystallinity in the resin. This will maximize mechanical, thermal, and chemical resistance properties. Full annealing generally requires 2-4 hours of heating at 130°C. The following process for annealing your ThermaX™ PPS parts will help assure ideal performance.
- Place printed parts in cool, room-temp oven. Supports may be left on the part if there is a risk of part warping without them.
- Set temp to 80°C and allow to stabilize for 1 hour.
- Raise oven temperature to 130°C and allow to stabilize 2-3 hours, longer depending upon the size/thickness of the part.
- Turn off oven heat and allow the printed part to cool to room temperature.
