Because it’s partially composed of water-soluble material, Caverna ST may absorb moisture. Always store your filament in the resealable bag it arrives in and ensure that it is sealed after each use.
The metal bag should contain a desiccant. Don’t throw it out, and consider adding another desiccant if available for additional moisture protection.
Never expose the desiccant to moisture. Otherwise, you’ll need to replace it.
If Caverna ST absorbs moisture while in storage, print quality will decrease. If that happens, dry at 70°C in a low-humidity environment for three to four hours.
Never store Caverna ST on the back or side of the printer.
