Product notification

This product has been discontinued and the end of service has passed. The information on this page remains available, but is no longer supported.

If material is not consistently flowing from the nozzle, this can show as little gaps in the print, irregular layers, or missing layers. In the worst case, no material extrudes from the nozzle at all anymore. 

There can be several causes for extrusion issues. This page contains some tips for your Ultimaker 2 or Ultimaker 2 Extended.

Material Feeder Nozzle PTFE coupler

Loading the material correctly and choosing the right settings are important to ensure good extrusion. Check the tips below:

Load material

When loading a new material spool, ensure that you follow the steps on the display correctly. When the filament is visible in the Bowden tube above the feeder, select Ready to start fast-forwarding to the print head. If you wait too long, this can cause grinding.

Material settings

Ensure that the selected material in the menu matches the material type installed on the printer. You can change the material type or customize the temperature settings via the Material > Settings menu.

Filament diameter Ultimaker 3D printers are designed for use with 2.85 mm filament. When using a third-party material, ensure that the filament diameter is correct and consistent. 1.75 mm filament cannot be used on the Ultimaker 2.
Move material It can help to manually move the material through the feeder. Go to Maintenance > Advanced > Move material and wait for the nozzle to heat up. Use the controller button to move the filament backward and forward and try to extrude some.
