XT-CF20 Carbon fiber filament

Hi,

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?

It wont work, there is no temperature range on the zortrax near to that.

Everything is from 260°C and above. Also you will loose warranty and since it is abrassive you might be damaging some other parts like hot end tube.

If you want to expderiment buy a cheap machine ie printrbot.

and start doing it.

Don't take too much these words "that they had only a slight hand finish" :) 

Hello everyone,

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.
 
Best regards,

Gijs
