Carbonfibre loaded filament


Hi, my first post.

Have any of you tried printing with carbon fibre loaded filament? I have tried with BASF PET CF Innofil but I am not having much luck. The material loaded OK but would not print. I cleared the nozzle in case the CF strands had blocked the nozzle but still no luck. When I unloaded the filament there was a very small cylinder of polymer on the tip of the filament, less than 0.5mm on a 1.75mm diameter filament, and what looked like grip marks on the filament itself.

I have increased the temperature up to 230c but it has no effect.

I am currently thinking that CF filament are too large for the nozzle, or that PET is beyond the heat range of the head.

Any suggestions very welcome.
