## Description

Our first special filament based on the Amphora 3D polymer. 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, butt 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
- Highly attractive matt black surface
 
**CARBON FIBER IS ABRASIVE:**

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.

**APPLICATIONS :**

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.

**Advised 3d printing temperature:** 240-260C (*XT filament produced before 7th february can be printed at 220 - 240C*)

**Advised 3d print speed:** 40 - 70 mm/s

**Advised Heated bed**
60-70C (*XT filament produced before 7th february can be printed on a cold bed*)
