Clean clogged printhead on Ulitmaker 3

Recommended Posts

Posted · Clean clogged printhead on Ulitmaker 3


I started a print on our Ultimaker 3 and after 20 minutes a "blob" of PLA had built up around the nozzle. As the printer apparently had printed continously on one place, the PLA entered the printhead and everything is clogged.

On a side note, I started the print on our second printer and it printed fine, so it wasn't the file.

I can't remove it mechanically while applying moderate force. Do you have any tips for cleaning up the printhead in this case?

Is there a tutorial how to disassemble the printhead?

    I have no tipps about removing it other than heating the print core and carefully prying the filament from the nozzle.

    But you should definitely contact your seller and ask about a replacement of the nozzle silicone cover.
