Using the Ultimaker 3 cleaning filament is the most effective way to unclog and keep print cores in optimal condition.
When to use the Ultimaker cleaning filament
The Ultimaker cleaning filament is used for both print core maintenance and unclogging procedures. We recommend performing regular maintenance once every three months. Unclog the print core if there is no material extruding from the nozzle for at least ten minutes.
How to use the Ultimaker cleaning filament
This filament can be used to clean any Ultimaker print core by applying hot and cold pulls. Hot pulls are used to get the biggest parts of carbonized material out of the print core and are highly recommended when the print core is clogged. With a cold pull, the remaining small particles will be removed, ensuring the print core is completely clean.
