Feeder Jamming and spilling

[andyg1002 0]

Hello everyone,

 

I'm looking for some help with my ultimaker 3 extend. When printing a nylon 3D model the feeder jammed spilling the material and practically destroyed the main feeder housing (see pictures). Has this happened to anyone before hand and if so is there I resolution to this? I am aware it is needing replaced but does anyone have knowledge on how to get it fixed?

 

Thanks in advance,

It's called a "head flood".

 

There are 2 possible causes - your door might not latch well and it could flop open during a print.  Or much more likely - your part came loose from the bed when it was wider than it was tall.

 

The solution is to make it so that the part NEVER COMES LOOSE.  This is harder than it sounds so I made a video.  Nylon is particularly easy if you squish well and use wood glue (or other PVA glue as shown in the video).  Also I like the bed at 80C for Nylon or even 100C but that's the least important detail.  Squish is most important.

 

Also it's important to replace the rubber silicone gasket that is missing on your print head.  They are very cheap.  Something like 5 for 5 dollars/euros.

 

Also your fan bracket is cracked - plastic parts are also very cheap from ultimaker.  Electronics and other hardware not so much.
