I have a XYZPrinting Da Vinci Mini W+ that I got for last Christmas. I am looking at the filaments available for it, since the included PLA is running 'low' (according to it) at 21 metres remaining. The one filament type that interested me the most is the Premium Metallic PLA. My question, that the website doesn't seem to answer, is how conductive is this material? Does it have any conductivity that would make it realistic to use to carry a current from something like an Arduino or Raspberry Pi, or is it too insulated, meant to only look metal, to act as a conductor?
Why I ask (Background - Not as Important) I ask this, because of an idea I had. Printing a pretty low quality PCB type circuit. Instead of being forced to keep my circuits on breadboards with wires jumping from here and there, I would take a conductive layer and sandwich is between to insulating layers. If I wanted two trace layers, I'd do the following pattern (with I being insulating and C conductive) "ICICI". Since I only can print in one filament type at a time, I'd print each layer in the thinnest thickness (1 micron, I believe), and have to fuse them together. I could do this in a few ways, using glue of some sort, or a hand-help filament pen to fuse the layers from the outside (the conductive layers would be slightly smaller, of course).
