PEEK thermal insulator Melt?!

[creativecode() 0]

Hi there,

perhaps some can tell me if this is normal. My Peek Insulator just look like its melted, and some of the PLA is going through some holes.

The Pictures should show what i mean.

Thank´s for the help.

Peek has a melting point of over 340C, I don't think the current heater could even reach that. At which temperature do you print?

I do have a tiny bit of oozing of PLA out of between the heater and the peek, but nothing like you see in your photos. So it's not normal I think.

Hi,

hmm i print at 200 - 230. Perhaps it was a software failure or something like that and the temperature goes over 340 °C?!

The problem is that the hole head (Alluminium block with nozzle and the brass pipe) doesn't hold on the PEEK insulator and so it fall of.

Hmm i try to fit it with some PFTE tape, but i think i need an new PEEL insulator.

230C shouldn't be a problem, I've printed at 250C, at which point the PLA starts to get a bit smelly.

You should contact Ultimaker for a new Peek part. But you better find out what's wrong with your machine before you replace it. Maybe you just have bad peek which melts at a lower temperature. Or your temperature sensor is not working correctly (but not going wild, as the machine will abort if it sees temperature over 275C or below 5C)
