Upgraded Titanium Heatbreak Thermal Printer Review

I was having issues with heat creep causing my Prusa Mini to jam, after switching to this thermal break and steel nozzle I had no jams!

which I bought about a month ago. I had no traffic jams or crawling problems. After weeks of fiddling around and trying a different hotend and extruder to no avail, I stumbled across this thermal break and decided to give it a try. Thermal paste, and since then my mini hasn't been sticking anymore. I use 1.75m of standard PTFE tubing from the extruder for the thermal break with no bevel. If you look at the CAD drawing you will see a flat area in front of the neck, this is where the PTFE tubing…

Of the two I received, one was 5.32mm and the other was 5.28mm. The stock Prus heatsink was 5.5mm thick. This provides poor contact and thus leads to poor heat conduction from heatsink to heatsink, which is NEEDED to prevent heat leakage (which is the reason for the 'upgrade'). I still have problems with heat creep and constipation. I used thermal paste to fill the gap but not enough to prevent thermal creep/clogging. I do not recommend this product until they can test tolerances of 5.475m +/…
