ESD ABS is a filament developed to protect or support objects sensitive to electrostatic current discharges. ABS ESD is a material that conducts electricity, but not as a copper cable, it conducts only what is necessary to derive electrostatic electricity. In case of needing electrical conductive materials we recommend Graphene Conductive Filament or Conductive PLA.

This material is based on Acrylonitrile Butadiene Styrene (ABS) and a Carbon Black additive. Carbon Black is a material produced by the incomplete combustion of petroleum products that has a really high surface/volume ratio and a large electrostatic and thermal conductivity. Its use is very widespread as a base for automotive tire reinforcement to improve resistance to stress and wear. In combination with ABS it results in a filament that can easily be used by any user with a 3D printer with a hot base, does not produce abusive wear on the nozzle, is resistant to abrasion (Shore hardness 77D) and what is more interesting, It dissipates the electrostatic discharges (ESD) thanks to the Carbon Black molecules are aligned in the form of nanotubes through which the charges that appear in contact with this material travels quickly.

This ABS belongs to the set of special ABS among which are the PC-ABS, the ABS Medical, the ABS CF, the ABS CAF, etc and the set of avanced materials such as PEKK, PEI, PEKK CF, PEI CF, etc.

The ESD ABS is widely used by all types of industries to make protective housings, support brackets and assembly tools for electronic components, which are very sensitive to electrostatic electricity discharges, such as the assembly of a hard disk. Another common application of this material is to make dust-free parts for laboratories and high-development centers, since most commonly used plastic materials attract dust and dirt by accumulating static electricity.

To achieve the maximum possible electrostatic conductivity, it's recommended to use the highest extrusion temperature recommended by the manufacturer (270ºC).

3D printing with ABS filament is a bit more complex than with the PLA filament. In the case of the ABS CF filament, it's necessary that the printing base is hot, between 90 and 100ºC. In addition, the temperature of the extruder should be between 250 and 270ºC. It should also be remembered that ABS plastic undergoes the phenomenon called "warping", which causes the first layer of the pieces to detach from the base of the 3D printer. So if you are going to print large pieces it's advisable that you use BuildTak, Kapton Tape, Magigoo or DimaFix so that the pieces don't tend to detach from the base and the filament cleaner to remove all types of dirt before the material enters the extruder and thus avoid clogging.. To ensure the dimensional stability of the parts it's advisable to use a closed 3D printer.

With ABS CF it isn't necessary to use reinforced nozzle since this filament has low abrasion but if nozzles are recommended with output diameters of 0.5mm or greater. Although it is not indispensable, it is recommended to use the Olsson Ruby Nozzle for all advanted materials.
