Due to the carbon short fibers and peeling short fibers in filaments, nozzles will wear during extrusion. After printing a certain amount of filaments, the nozzle diameter will increase, leading to a decrease in print quality. Therefore, it is necessary to replace nozzles with more wear-resistant materials. Hardened steel nozzles are usually chosen as print nozzles for fiber-reinforced filaments.
Since nylon filaments easily absorb moisture from the environment, printing with wet filaments will cause serious stringing. Therefore, it is usually necessary to dry the filaments before printing and keep them dry during printing.
We recommend using glass with a smooth surface and applying glue (or spray adhesive) as the printing bed surface. This will ensure sufficient adhesion to guarantee a high printing success rate.
The following are some key parameters for the filaments we tested, and we also provide print configuration files that can be directly imported into Luban.
Filaments | Printing Temperature / Bed Temperature | Retraction Distance | Retraction Speed | Printing Speed | Travel Speed |
---|---|---|---|---|---|
PA6-GF | 280 ℃ / 50 ℃ | 1.5 mm | 30 mm/s | 60 mm/s | 200mm/s |
PA6-CF | 280 ℃ / 50 ℃ | 1.5 mm | 30 mm/s | 60 mm/s | 200mm/s |
PA12-CF | 260 ℃ / 50 ℃ | 1.5 mm | 30 mm/s | 60 mm/s | 200mm/s |

It should be noted that the printing temperature and heated bed temperature of different filaments will be quite different, please read carefully the recommendations provided by the filaments manufacturer.
