For Ultimaker print cores
A pack of ten 20 cm long cleaning filament pieces to ensure your Ultimaker print cores are always in optimal condition. Especially effective for cleaning a print core BB.
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.
