Conductive PLA filament of Proto-Pasta is composed of polymer (PLA), a dispersant and conductive carbon. It's a semi-flexible material and compatible with any desktop 3D printer.
Conductive PLA filament Proto-Pasta is ideal for use in low voltage circuits, digital keyboards that require low conductivity, Arduino, tactile sensors, robotics and electronics.

The conductive filament PLA is feasible to track any item through a resistance 1Kohm. Conductive PLA filament is more flexible than the PLA has a lower adhesion. It also presents a softening temperature similar to the PLA (around 50 degrees). As for its rigidity is low; could be considered a semi-flexible material (fracture occurs when folding the pieces repeatedly). If you want to print double head is recommended for use in conjunction with the PLA.

The main features of the PLA conductive filament are:

Resistivity volumetric filament without 3D printing: 15 ohm cm
Resistivity volumetric 3D printed parts perpendicular to the layers: 30 ohm-cm
Volume resistivity of 3D printed parts through layers (along the Z axis): 115 ohm-cm
Resistance to a length of 10 cm filament 1.75 mm: 1.8 Kohm
Resistance to a length of 10 cm filament 2.85 mm: 0.6 Kohm

It is advisable to use a hardened steel nozzle or Olsson Ruby since the particles are quite abrasives and wears out the brass nozzles.

Print with Conductive PLA Filament Proto-Pasta is almost as easy as printing with the standard PLA. It is not necessary to have a warm bed 3D printer to print the PLA conductive filament, although in the case of having a 3D printer heated bed is recommended for use to 50-60 °C because a higher adhesion is obtained.

Adherence of the first layer is key and probably the most important factors for good impressions. so you can use Magigoo, BuildTak, Blue Tape or 3DLac.
