Why is it important that CarbonX™ CFR Nylon is a semi-aromatic polyamide? Semi-aromatic nylons have a large cyclical structure in its backbone which makes them stiffer, more chemically resistant, less moisture sensitive, and have improved dimensional stability vs. aliphatic nylons such as PA6, PA66, and PA12.

Chemical Resistance Chart
Please note: Customers should test their parts to determine end-use suitability using this polymer.
CarbonX™ CFR Nylon (Gen 2) is suitable for use in practically any desktop 3D Printer that has a heated bed. Please note - carbon fiber reinforced filaments are abrasive and can wear out a brass or aluminum nozzle. We recommend our A2 Hardened Steel Nozzles - HERE
High Modulus Carbon Fiber - excellent stiffness
Lower moisture uptake vs. PA6
Improved chemical resistance vs. PA6
Less shrinkage / warp vs. PA6
Recommended Print Conditions:
Extruder: 260-270°C is ideal, up to 290°C if needed. CarbonX™ CFR Nylon exhibits improved layer bonding at higher temperatures.
Bed Temp: 80 - 100°C
Bed Prep: Polyimide Tape, Clean glass with ABS/Acetone Slurry
Nozzle: 0.4mm or larger. We currently recommend our A2 Hardened Steel Nozzles - HERE
Layer Height: Ideal layer height is 60% of nozzle diameter. We do not recommend printing layers below 0.2mm with CF Grades.
Drying - very important. This product is supplied dry and sealed in thick 4mil pouch with several packs of desiccant. However, it is made using nylon and will absorb more moisture than other resins when left exposed to the environment. Excessive moisture will result in popping at the nozzle (water boiling off, a little steam) and excessive drooling and nozzle build-up. Make sure to keep this filament in a dry location between uses. If the filament does get wet, you can dry it out with a basic toaster oven (not one for the family food!). We recommend drying it for 2-3 hours at 70-80°C. Caution: Make sure to check back often to make sure you're not distorting / melting the reel - the reel itself has lower thermal resistance than the nylon filament and will distort / melt before the nylon.
