Cleaning 3D printer filament is not used to to print objects, but to clean 3D printer extruders. It’s purpose is to remove any material in the hot end that might have been left over from previous prints. Especially useful when transitioning between materials that have different print temperatures or colors.
The cleaning filament is used for both regular maintenance and unclogging of the print core. Regular maintenance should be done once every three months and the print core should be unclogged when material is not flowing from the nozzle for at least 10 minutes.
- “Print” temperature depends on whatever 3D printer filaments you used before, as well as on the one you want to use next. (Cleaning 3D printer filament is stable anywhere between 150 and 280°C.)
- It’s not typically necessary to use more than 10 cm of filament at a time.
How to use cleaning filament?
Regular maintenance of the BB print core should be performed once every three months. Using the Ultimaker cleaning filament is the most effective way to clean and unclog the BB print core on the Ultimaker 3. If you don’t have the Ultimaker cleaning filament at your disposal, you can use PLA instead.
Cleaning filament can be used to clean the print core on an Ultimaker 3 by applying hot and cold pulls. Hot pulls are used to get the biggest parts of dirt or carbonized material out of the print core and are especially necessary when a print core is clogged. With a cold pull, the remaining small particles will be pulled out, ensuring the print core is completely clean.
