ColorFabb XT CF20 Carbon Fiber 3d filament Canada


ColorFabb XT-CF20 Carbon Fiber - Black - 1.75mm
Free Gift


Reinforced with 20% specially sourced carbon fibers, this filament is perfect for parts which need high stiffness. XT-CF20 has a beautiful matte surface finish when printed.

colorFabb XT-CF20 is a copolyester based carbon fiber composite material that is based on the unique Amphora 3D polymer from Eastman Chemical and is loaded with no less than 20% specially sourced carbon fibers suitable for 3D Printing.

Combining carbon fibers in filaments material is not a new idea, but colorFabb has been able to combine a lot of desired properties into 1 new material:

  • Extreme High Flex Modulus (6.2 GPa) / twice as stiff as PLA
  • Moderate strain at break (8-10%), so no extreme brittle filament, but toughness
  • High Glass Temp. (Tg = 80C)
  • Very high Melt strength
  • Very high Melt Viscosity
  • Good dimensional accuracy and stability
  • Low odor / Styrene Free solution
  • Easy processing on many platforms
  • High attractive matt black surface


Just think of all the great applications for a variety industries, that now will have a material that performs according to expectations. Functionality, stiffness, dimensional stability, heat resistant, what more can you ask? Applications in the RC Industry / Drones / Aerospace / Automotive / Prototyping and many more can now be developed on your desktop 3D Printer.

Net Weight: 750g

Printing temperature:

Print speed:
40 - 70 mm/s

Heated bed

Build platform
Print on a heated bed. If you’re using aluminum of 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.

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.
