Is PLA filament conductive? I am planing on printing something that will make contact with PCB boards. The print will be most likely to be in PLA. I don't want to fry the PCB board so I want to know if 3D printed PLA objects are conductive.

I googled and found out about special non-conductive PLA and conductive PLA. But what about the conductivity of normal PLA?
Normal PLA is non-conductive. You can take an $\Omega$-meter to a test part if you're really concerned somehow you have some PLA that is conductive.
There is a caveat that your color may include metal flake or graphite of some kind. Depending on the density it may be conductive. But I've tested my silver on hand and it gave me infinite resistance.
