Proto Pasta Conductive-PLA Filament is one of the best electrically conductive filaments on the market. This filament can be used, among other things, for printing antistatic components or in low-voltage applications. The electrical conductivity of the filament is not comparable to copper or other conductors. The use of conductive filament is reserved for experienced users, and using the objects under electrical current is expressly at your own risk.

How conductive is this filament? The conductivity of printed objects depends on many factors, such as the geometry of the component, the infill used, and the layer height. Therefore, the values provided here should be understood as guidelines and cannot be guaranteed.

• Volume resistivity of the molded plastic (not 3D printed): 15 Ohm-cm
• Volume resistivity of 3D-printed parts along the layers (x / y): 30 Ohm-cm
• Volume resistivity of 3D-printed parts across the layers (z): 115 Ohm-cm
• Resistance at a length of 10 cm and 1.75 mm filament: 2-3 kOhm
• Resistance of 10 cm length with 2.85 mm filament: 800-1200 Ohm

Suggested applications: Protopasta Conductive PLA is an excellent choice for low-voltage applications, touch sensor projects, and using prints to interact with touchscreens that require low conductivity. Generally, anything that you can run through a 1K resistor should be possible with our material, provided you design the conductors to the correct size. This will easily allow an Arduino to run with low power if you are not operating many devices. Also, experiment with ESD or 3D-printed bearings!
