Conductive filaments are emerging 3D printing materials that have the ability to conduct electricity. The usefulness of these filaments in small DIY projects and circuits makes them very popular these days. You can make Keyfobs, LED-related gadgets, and bed-leveling sensors by using conductive elements. There are many companies that are making conductive filaments but here we will talk about the 7 most conductive 3D filaments.
The base material of these conductive filaments is mostly PLA. Some other materials like Acrylonitrile Butadiene Styrene (ABS) are also used. The conductivity of such filaments is ensured by introducing some additives like Graphene or Graphite-loaded Carbon materials.
This article will discuss a list of the most conductive 3D filaments of 7 reputable brands with their detailed properties and price.
