ESD Safe PolyMax™ PETG
PolyMax™ PETG-ESD is a popular electrostatic dissipative filament chosen for 3D printing assembly jigs, custom anti-static trays or electronic cases along with custom 3D printing solutions for hobbyist electronic projects.
Electrostatic discharge (ESD) materials are plastics that reduce static electricity in order to protect electrostatic-sensitive devices. Demand for ESD properties are heavily found in the manufacturing and prototyping sector. For prototyping applications generally revolve around casings and in the manufacturing sector revolve around jigs, fixtures and assembly or manufacturing aids for factory lines requiring anti-static materials.
PolyMax™ PETG-ESD is compounded with carbon nanotubes that allow it to dissipate electrostatic charges thanks to its very low surface resistivity. Combined with durability and a heat deflection temperature of 76°C, PolyMax™ PETG-ESD is a trusted choice for production of manufacturing aids for the electronics industry.
One example of a custom solution made possible with additive manufacturing and PolyMax™ PETG-ESD is a customised connector for FFC (Flexible Flat Cable). FFC are connection structures commonly used in electronic devices, in this example a motion control company needed a custom connector to connect rotary motors and optoelectronic switch devices. 3D Printing enabled a complex geometry that would be difficult to produce through traditional machining and bypassed MOQ and unstable lead times.
The connector printed in PolyMax™ PETG-ESD is designed in two parts, and once assembled, it can securely hold the FFC inside, with its ends connected to the rotary motor and other electrical components. The rotary motor drives the continuous rotation of the FFC, while the connector allows for separation and rotation. The design also includes limiting slots to prevent the cable from tangling or breaking. After the parts are printed on the same day, the customer can immediately proceed with the trial installation.
Considering that the FFC ribbon cable will experience continuous friction as it rotates with the rotary motor, the material choice for the connector must be wear-resistant while providing protective properties. In addition, the electronic components require ESD-safe characteristics. PolyMax™ PETG ESD from Polymaker becomes the ideal choice for the material used in producing these parts and reduced the cost by 85% compared to aluminium machining.

| Printing Speed | 30 mm/s - 50 mm/s |
| Retraction | The ideal retraction settings vary from printer to printer and depend on the hot end. The following settings have been a good starting point for many machines. Direct Drive: Retraction distance of 1mm with retraction speed of 20mm/s Bowden: Retraction distance of 3mm with retraction speed of 40mm/s |
| Infil / Minimal Wall Thickness | Due to dispersed CNTs (Carbon Nano Tubes) in PETG ESD, we recommend to print model with higher infill density and minimal wall thickness of 1.5 mm for a better interlayer bonding quality and ESD property. |
| Enclosure | Recommended for moderately sized models or cold / unstable printing environments. |
| Recommended Support Material |
Single Extrusion: |
Based on 0.4 mm nozzle. Printing conditions may vary with different printers and nozzle diameters.
We recommend to use a wear resistant nozzle when printing PolyMax™ PETG-ESD. CNT additives in ESD filaments are abrasive on printer components and will wear a brass nozzle or brass extruder gear faster than traditional materials.
PETG is a 'sticker' material in comparison to regular PLA. When it comes to printing PETG without stringing or blobs it's recommended to keep the filament dry and tune temperatures, retraction, speeds and flow to avoid build up of excess material on the nozzle.

Compatibility
PolyMax™ PETG-ESD has been engineered with compatibility in mind to print excellently on a wide range of 3D printers equipped with a heated bed. PolyMax™ PETG-ESD like other materials is hygroscopic. This means that it is susceptible to absorbing moisture from the atmosphere which can subsequently affect the quality and mechanical properties of the final prints. See "Storage and Drying" details below for instructions to protect PolyMax™ PETG-ESD.
The CNT's in ESD materials are abrasive, we recommend customers first install a more wear resistant nozzle before printing with this filament. Reinforced filaments tend to be stiffer and more brittle than other standard filaments. It is recommended to take extra care and make sure your filament guide system is smooth and with minimal bends to avoid snapping the filament.
Of course with thousands of unique 3d printer models on the market, we can't guarantee each filament type will work with every 3D printer.

The typical values presented in Polymakers data sheet are intended for reference and comparison purposes only. Due to the nature of 3D printing they should not be used for design specifications or quality control purposes.
STORAGE & DRYING
Before packaging, PolyMax™ PETG-ESD is dried to ensure the best printing quality and filaments are vacuum sealed to protect the filament from moisture. When not in use PolyMax™ PETG-ESD should be stored away from sunlight in the packaged resealable bag.
Like other PETG filaments, PolyMax™ PETG-ESD is susceptible to absorbing moisture from the air which can subsequently effect the quality and mechanical properties of the final prints. We recommend storing PolyMax™ PETG in the PolyBox™ or a dry cabinet during printing to prevent moisture absorption which will lower the quality of the print. The PolyBox™ keeps the filament at dry conditions (relative humidity of 15% or less).
If you hear popping sounds and notice that the surface quality of your print is uneven or the color is not consistent, this is a likely indicator that the filament has absorbed too much moisture. Spools of PolyMax™ PETG-ESD can be dried in a preheated convection oven at 65˚C for up to 6 hours. Results may vary depending on the accuracy of your oven so please be conservative. For more information about filament drying please read our user guide.
FAQ
Q: Should I rewind this filament if I want to use it with a different spool?
A: We strongly advise against tampering with the product by rewinding. See our article for full details about the risks. All Polymaker filaments are wound with tension but without strain. Rewinding completely rearranges the curvature of the winding and this strain over time can cause most plastics to catastrophically break. If for some reason your printer is locked into fitting less than standard sized spools, there may be safe printable adaptors or external mounting solutions available.
