There's a Kickstarter running right now for a machine that prints circuit boards. Rather than a traditional etching process, they use conductive (silver-based) ink to print traces and pads. It has a resistance of 12 m\$\Omega\$/in^2. What design limitations does this impose? More specifically, what kinds of circuits would I not be able to produce with these parameters?
I assume high frequency things like high speed busses (LVDS?) and printed antennas? Other things?
Note: I am specifically not placing a link to the project here as this question isn't meant as an advertisement for it.
