PLA Leak

Recommended Posts

I have a problem with my ultimaker, it is leaking PLA between the aluminum heater block and the brass pipe.

I have tightend the brass pipe as hard as i can without breking it but it still leaks.

Any ideas how to fix it?

A slight leakage seems normal and many UM users experience that phenomenon. Normally that leak seals itself when the PLA degrades. Then it becomes dark or even black (unless you're already printing black PLA haha) and it gets hard and brittle sealing that tiny leak.

Nevertheless a photo would be nice so we can guess how strong that leakage is.

Hello Guys

Thanks for your answers, picture can be found in my album:

However after the last picture was taken i've taken apart the head and tigthened the brass pipe when it was still hot, and it seemes to tighten much more, so now there is very little leak any more, maybe its going to seal it self like "trion" said.

Thanks!
