Using Bambu Lab PAHT-CF Filament is easy. First, dry the filament at 80°C for 8 - 12 hours before printing. Keep the container's humidity below 20% RH with a desiccant. Set the nozzle temperature between 260 - 290 °C and the bed temperature (with PVP glue) at 80 - 100 °C. Print at a speed of less than 100 mm/s. Remember, this filament has high thermal insulation requirements, so it's not suitable for open-frame printers. For better drying, you can dry it at 80 ℃ for 5 hours in a filament dryer or 90 ℃ for 10 hours on a heat bed, but don't exceed 100 ℃ to avoid melting the spool. Check the Filament Drying Procedure on WIKI for more details. Also, refer to the Printing tips for Engineering materials on WIKI for better print results. After use, store the filament in a dry place to maintain its quality.
