What is Carbon-fiber nylon?
PA6-CF and PAHT-CF are nylons reinforced with chopped carbon fiber. Nylon brings toughness and heat resistance; the carbon fiber adds stiffness and keeps the part dimensionally stable. PAHT-CF is a high-temperature grade that absorbs less moisture, so it holds its properties better in humid or hot conditions. Both are dried before printing and run through hardened steel nozzles in a heated chamber.
Design tips for Carbon-fiber nylon
- Design like a molded part: ribs and gussets add stiffness without weight.
- Keep walls at 2 mm or more for load-bearing features.
- Orient the load along the layers; tell us the direction of force.
- For tight locating features, leave stock for reaming or design in bushings.
Nozzles: 0.4 mm as standard, 0.6 mm for larger parts printed faster. General tolerance is ±0.5% with a lower limit of ±0.5 mm. More in the design guide.

Carbon-fiber nylon 3D printing FAQ
What is the difference between PA6-CF and PAHT-CF?
Both are carbon-fiber nylons. PA6-CF is the tougher, lower-cost grade for brackets, jigs and frames. PAHT-CF is a high-temperature grade that absorbs less moisture, so it keeps its stiffness in hot, humid and under-hood conditions.
Can carbon-fiber nylon replace metal parts?
For many light-duty brackets, fixtures, guards and housings, yes. It is far lighter than aluminum, needs no machining and is ready in days. Tell us the load and temperature and we will advise.
How hot can carbon-fiber nylon get?
Both grades hold their shape well above 150 °C, which covers most engine-bay brackets, motor mounts and parts near heaters.
Is carbon-fiber nylon good for jigs and fixtures?
Yes. It is stiff, wear-resistant and stable, which is why it is the standard material for printed assembly jigs, drill guides and soft jaws.
