Bring your 3D printed projects to life with this electrically conductive PLA filament! The conductive properties come from graphene imbedded in PLA which is a biodegradable, environment-friendly plastic that doesn't have the notable smell of hot plastic, compared to ABS during the printing process.
Bulk resistivity is 0.6Ω/cm³, this is expressed in ohms per cubic centimetre not per linear centimetre as it refers to the resistance of a printed object. Resistance measurement is taken by measuring across opposite sides of a 1cm cube with full contact. The unprinted filament measures around 300kΩ per linear metre so it is mostly suitable for signal level voltages, but it is conceivable that you could illuminate some LEDs for example.
Note: Due to the additive in this filament it is very brittle and should be handled with care.
