FDM material
Conductive PLA (Carbon-Loaded) 3D Printing
PLA loaded with conductive carbon black. Conducts enough current for capacitive touch sensors, low-voltage LED circuits and simple switches, but its resistance is far higher than metal and depends on geometry and print direction. Not a replacement for wire. More brittle than plain PLA.

Conductive PLA: common questions
What is Conductive PLA good for?
Conductive PLA is a common choice for capacitive touch buttons, low-current circuits, electronics education, sensor prototypes. PLA loaded with conductive carbon black. Conducts enough current for capacitive touch sensors, low-voltage LED circuits and simple switches, but its resistance is far higher than metal and depends on geometry and print direction. Not a replacement for wire. More brittle than plain PLA.
How strong and heat-resistant is Conductive PLA?
Printed Conductive PLA parts have a typical tensile strength of 25–35 MPa and heat resistance of ~55 °C. These are typical values for printed parts in the XY direction; strength between layers is lower, so orientation matters for loaded parts.
How big a part can you print in Conductive PLA, and how fast?
Up to 350 × 320 × 325 mm in one piece; larger parts are printed in sections and joined, after a review. Production takes 2-5 business days, and rush service is available.
