PETG ESD

The PETG ESD filament by Nanovia is their second ESD filament apart from Nanovia ABS ESD. PETG ESD is a composite material with a PETG base and ceramic particles and unlike most carbon based ESD filaments, the Nanovia PETG ESD filament doesn't leave any residue in the case of friction (ideal for clean rooms) and does not cause excessive nozzle wear.

This filament's antistatic properties come from the integration of conductive ceramic charges. These allow for the gradual evacuation of accumulated static electricity generated by electronic components and friction along the surface of an object 3D printed with the Nanovia PETG ESD filament. ESD-safe materials are indispensable in environments where the sudden discharge of electrostatic energy could can cause damage to sensitive electronical components or even an explosion of volatile powders.

With tools, jigs, fixtures and storage containers 3D printed with the Nanovia PETG ESD filament, instant or latent damage to sensitive electronic devices can be avoided. Thanks to this filament's good heat resistance, parts printed with PETG ESD can house circuit boards and components that heat up to 80 °C when operating.

The Nanovia PETG ESD filament is easy to print, does not require a heated chamber (although it can be used), and is compatible with most commercially available FFF 3D printers. It is of utmost importance that parts printed with the PETG ESD filament are not painted as this could inhibit the material's antistatic properties.
