Conductive materials quality 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:


I suppose that since I need to do multi-material printing, i will have to stick with FDM. Is that correct?
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?
Someone has already studied this: study of electrical properties of 3D printed materials.

ABS: dielectric constant about 3.
PLA: 2.7-2.9.
