CFC PA is Nylon based material developed by Polymaker for use in Anisoprint CFC (continuous fiber coextrusion) process. Lower viscosity allows for better binding of fiber layers, while fast cooling and solidification rate helps to achieve a better quality of fiber placement. This plastic is also low absorption grade and can be printed from open air for a decent amount of time.
MAIN PROPERTIES
As most other plastics from Nylon family, Smooth PA is suitable for printing functional parts, requiring increased strength, toughness and durability.

Printing guidelines
NB! MAKE SURE YOU ARE USING THE LATEST VERSION OF AURA SLICER AND YOUR COMPOSER A3/A4 IS PROPERLY CALIBRATED BEFORE PRINT.
Temperature & Cooling
Smooth PA is best printed in between 250 and 270°C. Note, that this plastic is intended for use in the composite extruder of A4/A3 models only. It means it is always printed in pair of Smooth-CFC PA and is included in Smooth composite profile. General printing requirements are the same as for Smooth PA, however, in CFC process, more cooling from fans(50-100%) is recommended in order to achieve more neat fiber layup.
Speeds
Speeds of 10-20 mm/s are recommended in CFC process. The default speeds in standard Aura profiles are in this range.
Drying and storage
Unlike other nylons, CFC PA can be printed from open-air, without a significant decrease in part quality. When printing longer prints, the use of an active dryer is recommended at 60°C. Store the material in a dry place (sealed box with silica gel works well).
Nozzles
CFC PA is designed to be used with Anisoprint Composite Brass nozzle, but also can be printed with Composite Steel nozzle if required.
