I am new to 3d printing having only recieved it for christmas. The filament is jammed somewhere in the extruder of my Wanhao Duplicator i3 Plus. I have tried removing it with the included hook but was unsuccessful. Is there anything else I should try before I before I dismantle the extruder, which i very much want to avoid.

I follow the techniques spelled out in this video on Tom's 3d: Basics: Cleaning out a clogged nozzle!

Essentially you:

  • Heat up the hot end past the point you normally print at.
  • Manually (gently) push filament out of the hot end.
  • Turn off heat & continue applying pressure to the filament, until it quits extruding (it has cooled off).
  • Set the heat on the hot end to normal printing temprature for the filament & immediately start pulling firmly on the filament, but not too hard.
  • As soon as it melts enough, it will just "slip out" & bring any stuck crud with it.

I went ahead and bought some white nylon filament so I can heat it up hotter (good for cleaning out ABS) and since it's white, I can see the nasty crap it pulls out.

Try to preheat your printer, the temperature should be above 180°C then push the filament to come out from the nozzle just 4 to 7 mm, then take out the filament from the extruder. With this step the plastic lump will get soft and will release the filament.

Then use the tool to clean the nozzle pushing the residue inside the nozzle.

This is a common problem if someone tries to change the filament without feeding a little bit (3-5mm).
