Surface resistivity of PLA

[DaveB]

Does anyone know the surface resistivity of PLA? (Plain PLA with no metals or carbon added.) I have googled it, but I have not found anything relevant.

A typical range or specifications for a particular filament would be useful.

There are some conductive filaments. Conductivity ranges from 10^9 ohms/cm (good for ESD purposes) down to .6 Ohms/cm (Graphene) depending upon the material selected. There is a Co. that sells samples of that sort of stuff if you are interested, I think their name was 'global filament supply depot usa' or something like that.

I was thinking it might be static dissipative. I think the upper limit for that is 10^9 - 10^12 ohm/square, so looks like it is not..

Hi

There are no printable plastics that are dissipative in their raw form. The only way to make that happen is to either surface treat them or mix in additives.
