  1. This is a question about 3D printers. I don't know whether it is proper to ask you questions here...I hope someone can help me out. There are conductive filament for 3D printers which seem to have between 30 and 115 ohm/centimeter resistance depending on the axis. (Proto-Pasta conductive PLA) They can be 3D printed as a capacitor of 2 cubicly-interlacing-but-not-touching matrices as follows, with one negative and one positive: Does it have useful properties? I figure probably it could already be done, but here maybe it can be done at home simply and relatively cheaply, and so I wonder what that does, if someone can figure it out. I don't have yet the equipment to try. With a cheap printer I can't imagine doing more than 2x20x20x20 cubes, inside 20 * 20 * 20cm, with 1cm per side. I know that's surely not much compared to normal caps rolled onto themselves. I tried it with normal filament. The bridging is tricky, but it can be done, so I wonder about the theory. Sorry for the blurred image..An interesting thing about 3D printers is that it can create shapes of things nested one into the other. But I don't understand capacitors(http://www.kynix.com/Product/36.html) and so it's possible the effect cancels out and that it's of no use as it is, or that the standard plate-against-plate is better. Anyway, I'll be trying it eventually, or at the least, a standard configuration.
