Ultimaker print cores should be cleaned periodically for optimal results. Material can sometimes get stuck to the outside of the nozzle and degrade. Although this will not damage your printer, it is recommended to keep the nozzle clean in order to achieve the best print results.

Using the Ultimaker cleaning filament is the most effective way to clean and unclog print cores. If you don’t have the Ultimaker cleaning filament at your disposal, use PLA instead.
Tip: The AA print core does not require preventative maintenance. However, it is recommended to clean the print core when changing between materials that require different printing temperatures.
