3DXSTAT ESD-PETG is an easy-to-use ESD-Safe filament formulated for a wide range of applications requiring electrostatic discharge (ESD) protection and enhanced chemical resistance. Made using high-flow PETG copolymer and CNTs to provide exceptional repeatability and reliability.

3DXSTAT ESD-PETG

3DXSTAT ESD-PETG is an advanced anti-ESD compound designed for use in critical applications requiring electrostatic discharge (ESD) protection. Manufactured using cutting-edge multi-wall carbon nanotube technology, advanced compounding technology and precision extrusion processes. Target surface resistance of 107 to 109 Ohms.

The benefits of PETG include:

• Superior chemical resistance compared to ABS
• Amorphous structure that gives low, nearly isotropic shrinkage
• Low moisture absorption, 3 times lower than ABS
• Very low odor emitted during printing
• Superior ductility compared to ABS
• Wide working range of 230-260°C

The benefits of 3DXSTAT™ include:

• Constant surface resistivity
• Better impact and stretch retention
• Low particulate contamination
• Minimal contribution to outgassing and ionic contamination

Chemical resistance of PETG:

PETG molded unstressed tensile bars exhibit good resistance to dilute aqueous solutions of mineral acids, bases, salts and soaps, and to aliphatic hydrocarbons, alcohols and a variety of oils. Halogenated hydrocarbons, short-chain ketones and aromatic hydrocarbons dissolve or swell the plastic.

Typical ESD-PETG applications include:

• Semi-con: HDD components, wafer handling, masks, enclosures and connectors
• Industrial: transportation, measurement and sensing applications

Target Conductivity for 3DXSTAT ESD-PETG:

• Surface resistivity from 10^7 to 10^9 ohms on 3DP sample using concentric ring test method.
• Note: Internal studies have indicated that increasing the extruder temperature 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 part geometry. Therefore, expect some trial and error time to understand how this filament works in your specific printer/application. However, 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 ESD-protected part varies depending on the printer's extruder temperature. For example, if tests indicate that the part is too insulating, increasing the extruder temperature will result in better conductivity. Therefore, the surface resistance can be "tuned" by adjusting the extruder temperature up or down depending on the reading you receive from your end.

Recommended print settings:

• Extruder: 230-260°C
• Bed temperature: 60-90°C
• Bed Prep: Magigoo Bed Prep Adhesive and 3DXTECH Polyimide Tape
• Heated room: not required
• Supports: Water-soluble AquaTek X1 USM works great for complex parts.
• Drying instructions: 65°C for 4 hours.
