TCMUK3D Titanium Heat Break (1.75mm) compitable with Prusa i3 v6 Hotends and compatible 3d printers

The heat break didn't work well at first and kept clogging. This was down to my e3dv6 suffering from heat creep. After adjusting my power output on my 3d printer, the heat break is working flawlessly.Original score: 3/5Now : 5/5

Seems to be a very lose fit into my E3d block as if the threads have been filed down to take off the high spots, broke when trying to take up lose wobble. Incredible weak considering it's apparently Ti.

I ordered this in conjunction with the ‘s’ upgrade for my prusa mk3. I have used TCMUK bits before (thermistor, heater cartridge, fans and pinda probe) all previous bits have been great with no problems. The titanium heatbreak however was a different story. I have the E3D copper block and standard heatsink the titanium heatbreak was a very poor fit with excessive wobble almost like the thread was a size too small. Once fitted I was plagued with blockages on PLA PETG XT nGen HT CF20. I changed nozzles twice (both brand new E3D 0.4 ones) I got a print done in the end using 0.6 nozzle. I stripped and rebuilt the hotend multiple times with new PTFE liners cleaned and redone thermal paste but nothing worked. In the end I fitted the original heatbreak and all was fine. It was a shame as I noticed that when unloading the filament the end was very well defined (although the bulge was off centre) and with PLA you had no stringing when removing from the extruder so looks like it had a very well defined hot zone. Sadly I had to return it as it was in usable.I will say my friend who has the same printer and copper block/nozzle combo as I do has had complete success with the titanium break and is very happy. Perhaps I got a duff one or perhaps Jupiter was not aligned with mars and the wind was blowing in the wrong direction (a well known problem with 3D printing!!!)All in all it was a great shame as everything else I have brought from them has been absolutely fine and fits/works perfectly. It just happens that for me in this instance it didn’t

good

fantastic company to deal with ,totally honest and very good prices for what is top notch kit.these throats are way way better than standard e3d throats
