Researchers at Purdue University have developed a method for producing 3D printer filament with customizable electrical conductivity. This is the first technology for producing conductive filaments that allows for the controllable production of electrically tunable filaments with consistent conductivity. The ability to maintain consistent conductivity is critical to this area, as any variation can lead to inaccuracy in the final product's sensing performance. This technology can be integrated into all Fused Deposition Modeling (FDM) 3D printing processes. Potential applications for this technology include smart devices as well as 3D printed sensors or actuators.
