PRINTING TIP(S)

Store filament in a dry environment.
Drying filament before printing is required. Actively dry it with a filament dryer at 65°C for 8 hrs.
- If drying on AMS 2 Pro or AMS HT, dry at 65°C for 8 hrs.
- If drying on a Bambu X1C / X1E / H2D / H2D Pro printer's heated bed, dry at 75°C - 85°C for 12 hours.
- An airtight storage container with desiccant is recommended before, during, and after printing.
An abrasive-resistant nozzle (hardened steel, tungsten carbide, ruby-tipped, etc.) is required.
- Using a non-abrasive-resistant nozzle is possible, but will very quickly degrade the nozzle, leading to frequent replacements and print quality issues.
For streamlined filament extrusion, composite-reinforced filaments must print out of a nozzle that's, at minimum, 0.4mm in diameter.
For stronger Z-axis adhesion, increase the infill density. Avoid using an open-frame printer and refrain from setting the cooling fan speed too high, as overcooling can reduce layer bonding.
For a shinier appearance, use lower printing speeds and slightly higher nozzle temperatures.
The refill filament variant needs a reusable spool cartridge. See video below for instructions on swapping a refill onto a spool cartridge.
