Problems with printing conductive material. Material doesn't extrude.

[Akani 0]

I'm trying to print with conductive PLA on an Ultimaker 3. The brand of filament is FiloAlfa AlfaOhm. In the beginning, the prints came out of the printer okay. But after a few prints, it looked like the nozzle was clogged. I tried a cold pull and normal PLA would then extrude just fine. But when the conductive PLA was placed back, it wouldn't extrude anymore, as if the nozzle is only clogged for the conductive material.

For now, I am printing test strips to test the conductivity of the material. It has a dimension of 5x10x20mm and 5x10x30mm. I printed with the following settings:

Nozzle temp: 230°C

Bed temp: 60°C

Nozzle: AA0,4mm

Speed: 30mm/s

Flow: 102%

Layer height: between 0,1-0,2mm

Infill: 100%

Does someone have experience with conductive material or have some advice or solutions to this or similar problems?
