colorFabb PA-CF Low Warp 2.85mm X 700g

colorFabb

PA-CF is the first polyamide (aka nylon) produced by colorFabb.  It consists of chopped carbon fiber strands in a polyamide matrix.  The result is a filament with awesome mechanical properties.  It is easy to print with, can handle temperatures up to 120C for continued use, exhibits virtually no warp, minimal stringing, and is incredibly stiff and strong.  

In short, this filament has impressed us more than anything we have tested in a very long time, possibly ever.  We highly encourage you to try a spool for your functional objects.

From colorFabb:

The PA-CF Low Warp is a one of a kind polyamide formulation with the ability to print nearly warp free on non heated buildplatforms. Low infill prints come out perfectly flat on cold bed for higher infill prints 40/50C temperature is enough to obtain flat prints.

PA-CF low warp is infused with carbon fiber for increased stiffness. Users are recommended to use wear resistant nozzles, such as E3D Hardened steel nozzle or Olsson Ruby.

PA-CF Low Warp excels in tensile and impact strength and allows continues use at 120°C while retaining sufficient mechanical properties.

The formulation has been modified to reduce uptake of moisture and it also takes about 4 times longer to reach the saturation point compared to unmodified PA6. This makes PA-CF Low Warp less affected by moisture then most other nylon filaments available in the market.

 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. ColorFabb recommends to using wear resistant nozzles, such as E3D hardened steel nozzle or Olsson Ruby nozzle.  Edit:  PrintedSolid.com has also had great results with the 3DSolex Everlast.

Due to high stiffness of 2.85mm we recommend users to use spoolmounts which have some friction between spool and holder, to prevent unspooling of filament.

Material:
Colorfabb PA-CF Low Warp

Diameter Tolerance:
± 0.1 mm

Density:
1.4 g/cm3 

Continuous service temperature:
120C

Adviced 3d printing temperature:
260C-280C  

Adviced 3d print speed:
30 - 40 mm/s

Advised Heated bed (if you have one, not strictly necessary):
ambient - 50C

For heated glass plate build surface we can recommend using 3DLac for extra adhesion.  Printed Solid has had good success simply with glue stick on glass.  This material has excellent adhesion to the bed.

Advised layerheight 
For this material we recommend a minimum of 0.2mm layerheight. Due to the length of the fibers layers lower then 0.15mm can cause issues such as clogging or partial clogging of the nozzle.

Cooling fan
50% fan cooling is a good starting point, this gives best performance on overhangs and small details. For best mechanical performance try printing with the least amount of cooling needed, for optimal layer adhesion.
