With so many strong, flexible, and durable types of 3D printer filament available, structural and mechanical projects are everywhere, it seems. Enter conductive 3D printer filaments — filament that does as its name implies: conduct electricity. Time for electrical and computer engineers to join the fun!
With the addition of conductive carbon particulates to PLA or ABS, it’s easy to realize dreams of printing low-voltage electronic circuits. Just couple a conductive 3D printer filament with an ordinary PLA or ABS in a dual-extrusion machine.
When Should I Use Conductive 3D Printer Filament?
Even though this 3D printer filament type only supports low-voltage circuitry, the sky’s the limit with customized electronics projects. If you’re experimenting, try coupling a circuit board with LEDs, sensors, or even a Raspberry Pi! If you’re looking for something a little more specific, popular ideas include gaming controllers, digital keyboards, and trackpads.
