AI1 Leak - Plastic leaking Jan 3, 2016 13:51:14 GMT

It can be troublesome if like this picture your AllInOne hot end is leaking from the top of the heating element.
What might cause this:
- The bottom screws not properly tighten
- It's also important to make sure to tighten the screw when the hot-end is still hot as all the metallic parts are expanded.
- One of the internal part is not properly inserted or missing.
How can you Handle this situation?
The plastic mess that is located near the heating element and the metallic parts will be easy to remove.
- Just preheat the hot end and remove most of the plastic using metallic pliers.
- If the plastic is stuck inside the heat sink block, a heat gun can help, or a candle. Heating up the metallic body will help you to extract the plastic from inside.
- If you have a dremel you can also use a very small drill bit (1 mm) in order to drill in the middle of the plastic. After a few seconds the plastic will melt by the friction of the drill with the plastic. You should then be able to extract some of the filament from inside the body. Caution to drill in the very center. if you are slightly offset when drilling you may hit the metallic body damaging it's smooth surface. This can cause troubles later on when the filament will slide inside the hot end.
The plastic located around the thermistor and heater cartridge is more tricky
- If you have a heat gun you might be able to soften the plastic enough to remove it. Remember that a heat gun can heat more than 200°C and can damage some other components doing this. SO go easy with the gun.
- You can also try using a lighter locally during a very short period of time.
I hope this can help some of you.
