1cm3 test piece, 10.05x9.91x9.86 (mm) (XYZ), weight 1.19g. Density - 1.21g/cm3 .
A Black PETG filament that is designed for use where electrostatic discharge protection is required.
Temperature: Prints fairly well across the majority of the range although it began to lose layer bonding below around 230°C, Stringing was noticeable at all temperatures so increased retraction will help but approximately 245°C gave marginal better bridging appearance.
Speed: 40mm/s is ideal but will print at slightly quicker speeds, but could lose bonding between layers.
Volumetric Flow: 4mm3/s at 245°C.
Preferred settings: 0.4mm Nozzle, 245°C, 40mm/s with 70°C bed temperature, and increased retraction.
Ultimaker Robot: Produces a well-defined print with good definition to the ear-cups and antenna, as well as overhangs and bridging.
Tree Frog: Produces a nice print good definition all round, the increased retraction settings produced a nice finish to the legs and belly as well as a nice finish to the head features.
3DBenchy: Increasing the retractions part way through worked well in reducing the stringing, it’s difficult to see in the photo but a nice clean print other than the initial stringing before altering settings.

*As the vertical height can be effected by the distance of the bed-levelling to the nozzle the height of the “Top of the Chimney to the top of the box” should be more accurate for the comparisons
Conclusion: In general this was a nice filament to print with, it gives a nice satin black finish and with about 40mm/s print speed produced nice detailed features, I have not been able to check the ESD side of the materials specification. A couple of words of warning the manufacturer recommends NOT going about 270°C and post printing this required a lot of cleaning of the nozzle after use, normally only needing only 3-4 atomic pulls when swapping materials I needed 12 pull cycles to get it all out and I still wasn’t 100% certain I had got it all out.
