Two days ago i see this amazing filament http://colorfabb.com/xt-cf20/ produced by colorfabb with 20% of carbon fiber. I wrote to colorfab and ask me that the right extrusion temperature is from 240 to 260 degree and righ speed printing from 40-70 mm/s.
Obviously due to the abrasive quality of carbon fiber we need to change the nozzle often but maybe can do a good choice also for our zortrax! Anyone of us tried it?
The printers in colorfabb website (parts of machine) are done with ultimaker 2 and colorfab confirm me that they had only a slight hand finish.
I'm thinking about this new amazing filament! What do you think?
yesterday I contacted their support team on the filament, and they gave me this answer:
The XT-CF20 will need a printer which can print at 240-260C and a heated buildplatform that can go up to 60-70C, if the Zortrax can do this then there shouldn't be a problem.
Keep in mind the abrasive nature of Carbon Fiber particles, it will wear down brass nozzles. Advice is to print with stainless steel nozzles, or be prepared to replace brass nozzles when needed.
