This might be a better fit over on EE.SE; Someone can likely answer the printability questions here, but the capacitive properties of the materials is a little beyond the average "maker".

Even if you succeed in printing without any shorts, you are going to have horrible reproducibility problems.  Further, I doubt most PLA/ABS/whatever materials have a dielectric constant of any useable value.

There is Proto-Pasta's Conductive filament... no experience with it but you should use a 2-extruder setup, which contains "conductive carbon black", a form of very finely powdered graphite. https://www.proto-pasta.com/pages/conductive-pla

in the end i bought the Proto pasta conductive filament, and measured it. resistivity is what is advertised (3KOhm/10cm). The filament has also capacitance. i printed 2 sheets 2cmx2cmx1mm and whith a piece of paper in between i measured 0.1nF

I was considering the possibility to 3D print some capacitors with various forms and shapes in order to test them. I need to be able to print both the non-conductive and the conductive materials at the same time so I have the following questions:

1. I suppose that since I need to do multi-material printing, i will have to stick with FDM. Is that correct?
2. I have seen that there are some PLA materials that are mixed with dust of metals and become conductive themselves. Do they become also capacitive? Are there any better options for a conductive material in a multi-material scenario?
