This brand is really cool, I wish the spools werent 60$ because I am poor but try to build things. One day maybe they can sell the PLA filaments for cheaper, until then I will plan out dream builds and cry.

Been using this filament for a couple years now to make conductive parts for prototyping. It has been very reliable, prints well and electrical properties have been consistent. Just wish it came in colors!

Looks great, it conducts electricity, which is incredible.
