XT-CF20 – 2.85mm colorFabb Filament
colorFabb XT CF20 is a copolyester based carbon fibre 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 fibres 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
Carbon fibre is abrasive – A special point of attention is the abrasive nature of the carbon fibres. In general these fibres will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. There colorFabb recommends 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.
Amphora 3D polymer – ColorFabb XT-CF20 is produced wih AMPHORA 3D Polymer from Eastman Chemical. Amphora 3D Polymers is a specially developed co-polyester just for 3D Printing. It’s toughness and high meltstrength makes it the perfect material for producing fiber reinforced composites, providing the necessary viscosity for 3D printing, combined with a high toughness in the filament and end application.
In-house production – All colorFabb 3D printing filaments are produced in their own production facility, situated in the Netherlands. Since no external parties are involved in the making of colorFabb filament we can ensure consistent quality on every order.
Excellent diameter tolerance – An important machine in their production is the laser measurement systems used to check the diameter of our filament in real time during production. It’s measured over 1000 times per second and helps guarantee that each spool of colorFabb 3D printing filament is produced within the tolerance. colorFabb can guarantee 0,05mm +/- on both 2.85mm and 1.75mm colorFabb filament, which means you can rest assured that your printer is extruding the exact amount of material.
Packaging – Within minutes of production, a spool of colorFabb 3D printing filament is sealed airtight with a double barrier foil. To go the extra mile, it is also sealed with a fancy cardboard box that is used to ship the product. This ensures that colorFabb filament is fresh and ready for 3D printing when it comes out of the box.
In-house testing – The colorFabb testlab features a wide range of popular 3D printers. They’re continuously testing on the 3D printers to keep checking the quality of the materials we produce and to develop exciting new materials for the maker community. If you’re not sure how to print with colorFabb materials on your 3D printer, please contact us.
The following printers are used in the colorFabb lab:
- Ultimaker Original
- Ultimaker Original Dual Extrusion
- Ultimaker 2
- Makerbot Replicator 2
- Delta Tower (E3D hot-end)
- Felix 20
- Leapfrog Creator
Material science – ColorFabb was founded as a brand of Helian Polymers, a sister company of Peter Holland which has been active in the master batch and additives for the plastics processing industry. colorFabb’s knowhow, network and partnerships is driving material innovations and quality. You can expect colorFabb to keep on developing interesting new materials, which will be tested on a variety of printers to make sure it’ll get the job done.
Since colorFabb develops and produces their own filaments they have a lot of knowhow about our materials. Here you’ll find all kinds of interesting material specifications that will help you decide which material is best for your project.
