Electrifi 1$/g 0.006 Polyester The material stops conducting when it is stretched to much.
Blackmagic 3D Conductive Graphene PLA Filament 0.7$/g 0.6 PLA The material becomes brittle after over time.
Blackmagic 3D conductive TPU 0.2$/g 1.25 TPU Hardness: Shore 90 A. Currently only sold in filament form. The material becomes brittle over time
PI-ETPU 95-250 Carbon Black 0.1€/g 800 TPU Tensile Modulus: 12 MPa
