I have printed PA6-CF for the first time on my new H2D
The material has extreme strength and is printed at 290°C.
Adhesion was critical but it worked. with 100°C bed and 60°C chamber.
But … now I don’t know if I can get the nozzle clean again.
If the stuff needs 290°C to print, I can hardly push it out with PLA.
I’m worried that everything will melt together or clog.
What are your experiences and recommendations?
Recently I printed PPS-CF with the left nozzle and thought the same thing would happen. PPS-CF needs above 300c to melt so I know the 250-260c that the printer uses to flush wont work. I just took the nozzle out of the printer, heated it manually with a torch and pushed the filament out with a nozzle rod from the top. As soon as the temperature melted the PPS, it shot out of the end of the nozzle and cleared it. Has been working with PLA and PETG since.
I am not sure of any other way besides a cold pull or something like that, but with these strong filaments, I dont know if that would work.
