Greetings, hiveMind!The Title says it all – almost. Probably the PLA must be wet with salt water or other impurities. So if this is true, can we not make semiconductor circuits by adjusting the impurities in the water? What about PLA-based metal filaments like CopperFill and all those other “Fill” filaments?Maybe we will use non-porous filaments as the insulators and wet paths or hollows to guide the different semiconducting liquids to their junctions, and “wet” PLA for the conductors. This circuit block would be any shape and possibly operate in a few tanks of liquid, be water cooled, and make circuits?Just curious, Les http://ift.tt/2c5r8KX
