Ultimaker 3 Extruder Piece Melting

Recommended Posts

My office has just set up our Ultimaker 3 and have made a few successful prints. I have noticed today that this white piece on the underside of the extruder head appears to be melting. I'm not exactly sure what this part is called, or what it's purpose is, but I wanted to see if anyone else had seen anything like this.

I think you are pointing to the silicone nozzle cover.  It is a consumable.  Melting is normal and OK.  After a while you might like to replace it though.  That is not normally needed very often, but it depends I suppose on the printing temperatures you tend to run.


In Canada, it is a $3 part.  I keep a couple of them back.


You might find this article of use.



I hope this helps!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
