3D Printed Circuits

In this guide we’ll show you how to use conductive filament and glow in the dark Ninjaflex to create a flexible LED wearable!

This integrated circuit is semi-flexible and uses a coin cell battery to power 5 Adafruit LED Sequins. This project is aimed towards 3D Printer's with a dual extruder.

This project was an experiment to see how well Ninjaflex could adhere to conductive PLA filament. The two materials bond well together and their attributes compliment one another.

Inspire & Remix

We think the concepts in this project can be used to create really cool elements for cosplay props and costumes. Integrating conductive filament into your designs will allow you to create embed circuitry. The conductive filament can also be used for capacitive touch sensors!

All the materials to build this project are available in the Adafruit shop.
