Bambu Lab PAHT-CF Filament on Spool
Description
Bambu PAHT-CF is a composite of PA12 and carbon fiber. Inheriting the advantages of low water absorption from PA12 and high-performance carbon fiber, Bambu PAHT-CF offers excellent mechanical and thermal properties that can be maintained well even when the prints get wet. Higher Z adhesion layers and flexibility make it ideal for creating engineering parts such as functional prototypes, machining fixtures, injection molds, jigs, and low-volume production parts.
Printing Tips
- Drying conditions: 80℃ for 8 hrs. PA6-CF is highly sensitive to humidity. To achieve optimal printing performance, it is recommeded further drying before use and after storage. For more details please refer to: Filament drying instructions on Bambu Lab Wiki.
- Bambu PAHT-CF has high thermal insulation requirements during the printing process, making it unsuitable for use with open-frame printers.
- For better print results, please refer to: Printing tips for Engineering materials on Bambu Lab Wiki.
- Fully impregnating the surface of the prints with paint, wax and other water-proof coatings can inhibit water absorption and prevent them from becoming soft.
- Bambu PAHT-CF comes with a high-temperature resistant spool, which is not prone to deformation in the drying process. Continuing our concept of reducing plastic waste, the spool can also be reused with other Bambu refills.
- All printing parameters are embedded in RFID, which can be read through Bambu Lab AMS (Automatic Material System). Load and print! No more tedious setting steps.
