Using the Ultimaker cleaning filament is the most effective way to unclog and keep print cores in optimal condition. 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.
