F-Electric, a conductive filament for 3D printing developed by a brand new company called Functionalize, wants to be the perfect solution for those who like 3D printing and open hardware. Instead of breadboards and soldering, with F-Electric you can draw circuits and other electric components (buttons, switches, connectors...) directly via 3D printing. In this way it could be also possibile, with a dual extruder 3D printer, doing things like 3D printing at the same time the case of an electronic device and its circuits. Or putting circuits in parts of the device you normally can't reach. Or reach easily.


F-Electric's creator, Michael Toutonghi, decided to develop a new conductive material for 3D printing simply because soldering is not for him. When an open hardware project by him and his son wasn't completed because of this, he went looking for a conductive filament to 3D print the circuits they weren't able to solder. There wasn't any but, Michael discovered, a lot of people had the same problem. So he decided to find - and create - a solution: a conductive filament for common deposition 3D printers.

The result, after a few tests with graphene, is a filament made with a material based on carbon nanotubes. Its resistivity is about 1 Ohm/cm and this makes F-Electric transmit electric current at least 1,000 times better than any other conductive filament you can buy today, says Toutonghi.


This new material is available (and patent pending), F-Electric filament is available too and some 3D-printed objects shown by Toutonghi prove that it really works. Functionalize now launched a Kickstarter campaign to make an important step forward: they want to increase F-Electric production volumes and make it broadly available to all 3D printing community.
