PolyMax™ PETG-ESD is a popular electrostatic dissipative filament of choice for 3D printing of mounting fixtures, custom anti-static trays or electronic enclosures, as well as custom 3D printing solutions for hobby electronic designs.

Electrostatic dissipative (ESD) materials are plastics that reduce static electricity in order to protect electrostatic electricity sensitive devices. The demand for ESD properties is strong in the manufacturing and prototyping sector. Prototyping applications are typically related to enclosures and, in the manufacturing sector, jigs, fixtures and assembly or production tools for factory lines requiring antistatic materials.

PolyMax™ PETG-ESD is formulated with carbon nanotubes that allow it to dissipate electrostatic charges due to its very low surface resistivity. Combined with a durability and thermal runaway temperature of 76°C, PolyMax™ PETG-ESD is a reliable choice for the production of electronics manufacturing aids.

One example of a custom solution that is possible with additive manufacturing and PolyMax™ PETG-ESD is a custom connector for FFC (flexible flat cable). FFCs are connection structures that are commonly used in electronic devices, in this example a motion control company needed a non-standard connector to connect rotary motors and optoelectronic switching devices. Three-dimensional printing made it possible to produce complex geometry that would have been difficult to produce through traditional machining, and bypassed MOQs and unstable lead times.

 

The connector, printed from PolyMax™ PETG-ESD, is designed in two parts and once assembled can hold the FFC securely inside, and its ends are connected to the rotary motor and other electrical components. The rotary motor drives the continuous rotation of the FFC, while the connector allows separation and rotation. The design also includes stop slots to prevent the cable from tangling or breaking. Once the parts are printed the same day, the customer can proceed immediately to a trial installation.

Given that the FFC ribbon cable will experience continuous friction as it rotates with the rotating motor, the material selection for the connector must be wear resistant while providing protective properties. In addition, electronic components require ESD-safe characteristics. PolyMax™ PETG ESD from Polymaker is becoming the ideal choice for the material used in the manufacture of these parts and reduces costs by 85% compared to machining aluminum.

Settings when printing

Nozzle temperature	250°C – 290°C Wear resistant nozzle recommended.
Pad temperature	70°C – 80°C
Substrate material	Works well with most building surfaces, e.g. glass, BuildTak®, etc. Rigid build plates are recommended over magnetic flexible plates.
Treatment of the substrate	Apply EcoFixy, Magigoo Original or PVA adhesive to the build surface to improve bonding.
Cooling fan	LOW for better surface quality OFF for better strength
Print speed	30 mm/s – 50 mm/s
Retraction	Ideal retraction settings vary from printer to printer and depend on the hot end. The following settings are a good starting point for many machines. Direct drive: 1 mm retraction distance at 20 mm/s retraction speed Bowden: 3 mm retraction distance at 40 mm/s retraction speed
Fill/Minimum wall thickness	Due to the presence of dispersed CNTs (carbon nanotubes) in PETG ESD, we recommend printing a pattern with a higher fill density and a minimum wall thickness of 1.5mm for better interlayer bonding quality and ESD properties.
Inclogger	Recommended for moderate size models or cold/unstable printing environments.
Recommended support material	Single extrusion: Self-support.

 

Based on a 0.4 mm nozzle. Printing conditions can vary between printers and nozzle diameters.

We recommend that you use a wear resistant nozzle when printing on PolyMax™ PETG-ESD. The CNT additives in ESD filaments are abrasive to printer components and will wear the brass nozzle or brass extruder gear faster than traditional materials.

PETG is a “sticky” material compared to regular PLA. When it comes to printing PETG without filaments or droplets, it is recommended to keep the filament dry and adjust temperatures, retraction, speeds and flow to avoid excess material build-up on the nozzle.

Compatibility

PolyMax™ PETG-ESD has been developed 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 on protecting PolyMax™ PETG-ESD.
CNT in ESD materials are abrasive, we recommend customers first install a more abrasion resistant nozzle before printing with this filament. Reinforced fibers are typically stiffer and more brittle than other standard fibers. It is recommended to take extra care and make sure your filament guiding system is smooth and with minimal bends to avoid filament breakage.
Of course, with thousands of unique 3D printer models on the market, we can’t guarantee that every filament type will work with every 3D printer.

Storage and drying

Before packaging, PolyMax™ PETG-ESD is dried to ensure the best print quality and the filaments are vacuum sealed to protect them 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 moisture absorption from the air, which can subsequently affect the quality and mechanical properties of the final prints. We recommend that PolyMax™ PETG be stored in a PolyBox™ or in a dry cabinet during printing to prevent moisture absorption, which will reduce print quality. PolyBox™ stores the filament under dry conditions (relative humidity 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. PolyMax™ PETG-ESD spools 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 use caution.

 

Frequently Asked Questions

Q: Do I need to rewind this thread if I want to use it with another spool?

A: We strongly recommend not to interfere with the product by rewinding. All Polymaker filaments are wound with tension but without strain. Rewinding completely rearranges the curvature of the coil and this tension over time can cause most plastics to catastrophically break. If for some reason your printer is blocked from mounting smaller than standard size spools, there may be safe print adapters or external mounting solutions available.
