XT-Copolyester filament with carbon fibers in black.

Experimental filament.
For experienced user.

A special point of attention is the abrasive nature of the carbon fibers. In general these fibers will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. Therefore we recommend to use nozzle’s from Stainless steel or hardened copper alloys.

Print on a heated bed at about 60-70 °C. If you’re using aluminum or glass as the build plate we advice using glue stick to make sure the first layer sticks well and keeps the part from warping. After printing, the build plate needs to cool down to about 20-30 °C at which point you can remove the printed part. The suggested 3D print speed is around 40-70 mm/s.

Due to all the different types of hot-end it's extremely difficult to give a temperature advice. Please consider these tips, provided by the manufacturer, as a starting point to find the temperatures that work well in your setup. You may have to adjust the temperature settings slightly based on your type of printer.
