3DXSTAT™ ESD-Safe Polycarbonate (PC) Filament
Our unique ESD-Safe Polycarbonate (PC) is ideal for ESD applications where improved thermal, mechanical, and dimensional stability is needed.
3DXSTAT™ ESD PC is an advanced ESD-Safe compound designed for use in critical applications that require electrostatic discharge (ESD) protection and a high level of cleanliness. Manufactured with consistency in mind - 3DXTech starts with premium polycarbonate resin and then compounded according to a proprietary formulation of multi-wall carbon nanotubes and process / dispersion modifiers - giving you a filament with excellent printing characteristics and consistent ESD properties.
Benefits of Polycarbonate include:
- High Thermal Properties: 147°C Tg
- Amorphous: Low and near isotropic shrinkage
- Excellent ductility / impact resistance
- Very low odor emitted during printing
- Wide processing range: 265 - 300°C (Max)
Benefits of 3DXSTAT™ include:
- Consistent surface resistivity
- Improved retention of impact & elongation
- Low particulate contamination
- Minimal contribution to outgassing and ionic contamination
Typical applications include:
- Semi-con: HDD Components, Wafer Handling, Jigs, Casings, & Connectors
- Industrial: Conveying, Metering, and Sensing applications
Target conductivity for 3DXSTAT™ ESD Polycarbonate:
- 10^6 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.
Recommended Print Conditions:
- Extruder: Between 260 and 300°C depending on your printer / extruder. Ideal layer bonding is typically possible at 275 - 280°C.
- Platform Temp: 110 - 120°C
- Platform Prep: Kapton Polyimide w/ ABS Acetone Slurry coating
- PC absorbs moisture from the environment, therefore it is important to keep this filament dry between uses. You will see bubbles / hear popping if the PC gets wet. If this happens, dry the filament in a small oven at 150°F for 3-4 hours. Note, the typical drying temperature for PC is 120°C (not F), but the reel that the filament is supplied on will fail at 120°C. Therefore, do not dry the filament at this temperature unless you remove the length you want to print with from the reel.
