Bent E3D Hemera Zodiac Bi-Metallic Heatbreak
-
Hi guys, I just got a $65 Bi-metallic heatbreak for my E3D Hemera, using it on my Ender 5 Plus/Supervolcano.... and I had a bad nozzle to bed crash and the thing is now bent ... in the past i have had this issue with the titanium heatbreak and when i have tried to bend it back straight Immediately while hotend is hot ... it snaps and breaks ....
Should i wait until the heater block is fully cool than try bending it back straight? or is it better to do it while hot? This thing was super expensive so i really do not want to break another one ...
Thanks!!

@rockydubb in reality unless your up near 1000deg to anneal the metal (depending on the materials) you're probably not gonna make any difference with having the hotend hot or cold.
Trouble is metals work harden when they're deformed which makes them less ductile. This means they are much harder to bend back into shape again without applying too much force and breaking them...
If you can get the metal hot enough to anneal it, that can help reset the microstructure so it becomes more ductile again, but with it being bimetallic, you've got 2 different metals which will need to be annealed differently and the thermal differences might cause other problems.
You might get away with bending it back as is, as steel and copper (I assume that's what materials it is?) may be more ductile than titanium. But even so, you might still have a kink on the inside which may or may not cause you problems when printing
Good luck!

@engikeneer Thanks for the info... i ended up using my metal ruler and than slowley applied pressure slowwwwwwly ...
it took like 2 hours but i got it back straight and it is printing and working great! Thanks again for the info.

@rockydubb You could use stall detection to do a emergency shutdown?
