Cleaning filament is the perfect solution for switching printing colors or materials. Once you are done using one material, simply use 3-8 inches of cleaning filament to clear things out in your hotend. We reccomend using cleaning filament after printing with metal infused filaments to help extend the life of your hotend and nozzle.
Please note that cleaning filament can't be used to print parts - it should only be used to clean out your print head. Additionally, cleaning filament requires that you manually adjust your printing software so that you start printing at the temperature of the first material you used and end printing at the temperature that you will need for the next material you are planning to use.
