Black ESD PETG is a static dissipative 3D printing filament made by COEX 3D in Green Bay, Wisconsin. Use it to print parts that hold or touch ESD-sensitive electronics: assembly fixtures, component trays, PCB jigs and protective housings. The compound's manufacturer lists a typical surface resistance of 104 Ω.
It's PETG compounded with carbon nanotubes, which make it static dissipative. It keeps PETG's easy printability, chemical resistance, layer adhesion and dimensional stability, and needs no heated chamber, so it prints on standard desktop setups.
Typical uses
- Electronics assembly: component trays, PCB fixtures and jigs, protective housings
- Industrial tooling: conveyor guides, pick-and-place tooling, automated line components
- ESD packaging: custom transport cases, enclosures and guards for sensitive devices

Typical values for injection-molded samples, per the compound manufacturer's preliminary data sheet; not ratings of a finished printed part. How a printed part performs depends on its geometry, wall thickness and print settings, so test parts for your application.
Printing notes
- No heated chamber needed.
- The carbon nanotube additive is abrasive. Use a hardened steel or other wear-resistant nozzle.
- PETG bonds very strongly to glass and smooth PEI. Use a release agent such as a glue stick or WELD3D, or the print or the build plate can break when you remove it.
- PETG absorbs moisture. Store it sealed with desiccant. If you hear popping, dry it: the compound manufacturer specifies 4–6 hours at 60°C.
