Conductive filament is an emerging material type that\u2019s great for small DIY electronic projects or small circuits. Conductive means that electricity can flow through it, hence the filament\u2019s usefulness in projects like\u00a0key fobs<\/a>,\u00a0LED gloves<\/a>,\u00a0and even\u00a0auto-bed leveling sensors<\/a>.<\/p>\n

This filament often has\u00a0PLA<\/a>\u00a0as a base material, but other materials (ABS<\/a>, for example) are also used. Most \u2013 if not all \u2013 conductive filaments contain graphitized carbon material or graphene, among other additives, which establish the filament\u2019s conductivity.<\/p>\n

In this article, we\u2019ll discuss a little bit of the science behind conductive filament, its applications, and some of the best brands available to buy.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The Basics<\/h3>\n

Conductive PLA needs a power source (like a battery) to transfer electricity. Although the filament can handle electricity, we recommend that you don\u2019t test its limits, as burning the plastic can release carcinogens. Electrical stress tests have shown that conductive PLA can handle\u00a00 to 60 volts at or under 100 mA<\/a>, but this varies depending on the brand.<\/p>\n

Although the filament can\u2019t power your house, it can help with small projects, such as\u00a0custom PCBs<\/a>, circuits, or electronic components that can power small devices, for example LED lights or sensors. We say \u201csmall\u201d here because conductive PLA can only handle low-voltage devices. And by that, we mean projects that don\u2019t draw or require a lot of power to function. It\u2019s important to keep this in mind when considering applications.<\/p>\n

Voltage & Resistivity<\/strong><\/h3>\n

Some conductive filaments are more equipped than others for handling certain voltages. For this reason, we\u2019ll compare products according to their level of electrical resistivity, which is an inverse measurement of conductivity.<\/p>\n

Many who are familiar with electronics will already know resistance (measured in \u03a9), which is a fixed, component-specific value. On the other hand,\u00a0resistivity<\/a>\u00a0(measured in \u03a9\u00b7m) is a more general measure, describing how well a\u00a0material\u00a0<\/em>resists the flow of current. The resistance of an object depends on the object\u2019s resistivity and dimensions:<\/p>\n

R<\/em>\u00a0=\u00a0\u03c1<\/em>(l<\/em>\/A<\/em>)<\/p>\n

where\u00a0\u03c1<\/em>\u00a0is resistivity,\u00a0l<\/em>\u00a0is the length of the object, and\u00a0A<\/em>\u00a0is the object\u2019s cross-sectional area. Thus, a 100-\u03a9 resistor may have 100 \u03a9 of resistance, but the material it\u2019s made of could have any value for its resistivity.<\/p>\n

Math aside, all you really need to know for the purposes of this article is that the lower the resistivity, the more conductive a filament is, and vice versa. Also, we\u2019ll be presenting resistivity in terms of \u03a9\u22c5cm, which is what\u2019s most often provided by manufacturers.<\/p>\n

Comparing\u00a0Resistivity<\/h3>\n

The filaments on this list have a wide range of resistivity, so make sure you know what you\u2019re getting before buying. To help you gauge the significance of certain values, here are a few examples:<\/p>\n
