Filament is leaking above the heather block

Recommended Posts

Posted · Filament is leaking above the heather block

We have a brand new UMO+. The first prints looked fine, but we probably made an error when we putted the nozzle in the heather block.

Now it's leaking filament above the heather block.

I tryed to fix it. But because there's filament every were I can't get it loose or tighter.

Is there a trick to solve this problem.

I think I have to get it all loose en clean it and then put it together again.

But i can't get it loose

Just heat it up and you'll be able to take it apart. The leaked plastic in the threads acts as a very strong glue when it's cold.

I used bottle of air to push the leaked filament with the head hot. But for safety reasons this is something you shouldn't do. But it worked for me. But don't do it :)

After that it was just a matter of atomic pull and tight the nozzle properly. (Don't overdo or the bozzle/heater block) can suffer.

Heat the block to 180C and then just start removing the extra PLA and then you can unscrew things while hot. Be gentle using wrenches as brass and aluminum are not as strong as steel.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
