Topic: Filament oozing - what happen to my nozzle?

Hi.
I was doing some maintenance on my Solidoodle 3, and I suddenly saw that there was some filament oozing out over the heat block, and it was coming from the cold end of the nozzle(from the top).
The threads on the cold end was fine, so it doesn't look like the plastic is coming form the extruder part.

As you can see, there is some leftovers from some green filament I'm been using, so it looks like the thread pipe has been really hot, since the filament has escaped from the top of the cold end.

Any thoughts? smile
Ps, I have only been printing ABS.

Re: Filament oozing - what happen to my nozzle?

I recently had the same (but less drastic) thing with my E3D.
In my case, it was because I didn't have everything tightened enough.

Thanks. I will try to reassemble my nozzle and see if I can get it any tighter.

I have been having the nozzle in several parts from time to time, because of clogging, so it can be that I have been lazy on my last cleaning smile

When you put it back together, heat your hotend up through RH up to 210. Be sure you do not feed filament in it yet since you will be heating it just so it tightens up snug but don't force it. You will certainly want a good pair of thick leather gloves to do this since you don't want to burn your hand. I am failarly certain good thick gloves can be found in Norway big_smile

Thanks for the assambly tips smile

Btw, can I clean the plastic part of the nozzle with aceton, or will it be broken/dissapear? There is some ABS leftovers that I can't get out with normal tools.

I "believe" the PEEK is made with nylon. If so, a little acetone and a pipe cleaner should do the trick.
