This is a 3D printed Arc Reactor which i modeled in Blender 2.8, exported as .stl file and used Cura to generate the Gcode for the 3D Printer (Anycubic i3 Mega). It has animated RGB leds which are controlled by an Arduino Nano which is connected to a powerbank. The animation is an endless loop. The Arc Reactor consists of a transparent PLA (to emit the light from the leds) and a black PLA. For the coils i’ve used a red copper wire and I’ve sprayed some the rings silver and gold. I’ve also created a case with a belt to wear the Arc Reactor on my chest.
A few more impressions:
You can find more details in the video below and a Blender tutorial which explains how you can create your own Ark Reactor.
