Researchers 3D Print Resistors From Electrically Conductive Filament on a Desktop 3D Printer

In a paper entitled “ Characterization of resistors created by fused filament fabrication using electrically-conductive filament ,” a pair of researchers 3D prints resistors using electrically conductive carbon black and graphene-based filament. “With this novel capability to directly create electrical components integrated into 3D printed physical objects designers can envision and 3D print new and/or improved devices with embedded electronics, which they could not do before,” the researchers explain. Using biodegradable conductive filament to 3D print circuits offers environmental benefits, and 3D printing technology allows for more design freedom, enabling manufacturers to better integrate electrical components within objects. The researchers used a MakerBot Replicator 2X Experimental 3D printer, which has dual extruders, for their work. A test print was created, and then two modifications were made to the 3D printer: an extruder block upgrade, which helped improve the consistency of prints due to reduced slippage of the stepper motor […]
