[Original]Anycubic I3 Mega 3D Printer Extruder Print Head

Easy install and for the price it’s a must have I have 3 that I rotate between clogs and I’m up and printing in no time

My old hot end was getting tired so I replaced it with this. Its fantastic and breaths new life into an old Anycubic Mega

I bought this to replace the current anycubic hotend that is no longer usable due to the set screws being stripped out. This leaves me unable to swap out broken parts such as the thermistor. But the new one has the same fn issue. The set screws are so tight and of such poor material that they just strip (internally round out) even if you apply heat to release any thread lockers that could be present (there arent). So now I have two useless hot ends. Joy.

A+ perfect fit

I know it’s cheap but I still expected it to be somewhat usable. The hot end was seized together and I could not get it apart, also the description used to say it was for just Anycubic which they seem to have changed because this does not work with the predator.

Works good as new and identical to what originally came with the printer

For the cost it’s just easier to swap the whole hot end then trying to clean it out. 5 mins no clog and printing like a champ

I have gotten 3 of these over time. They all start to leak from the threads about 10-20 hours of printing. While they will work you need to keep cleaning them and you get blobs. If you can just upgrade to an E3D v6 do it. Otherwise, you will need to rebuy the extruder multiple times if you print any moderate amount.

Id probably give this 3.5 stars. The only problem is that I needed to swap the heatbreak tube with an all metal one since I run ABS sometimes and it ends up burning the PTFE over time. However this is assembled with so much torque that it is very difficult to get the heat break tube out without stripping the threads (which I have not done). I had to cool the heatsink+heatbreak tube in the freezer and then was able to unscrew it, still with difficulty, using a vice grips while protecting the threads with some rubber wrapped several times around them. They do not have any thermal compound between the heatbreak and the heatsink, so it was just torqued too much. Other than than Im sure its great, as long as there are no plans to take it apart I guess. I am using this with an Anycubic Kossel and the dimensions of this are the same as the one I am replacing, so it is a direct replacement for the Kossel (aside from the electrical parts which I cannot use).

Well, I installed it today to find the thermistor is trashed. Smoked instantly. Unfortunately I looked and found my return window ended YESTERDAY. I was worried it might be the main board, but Ive got two other hot ends that tested fine on this machine. Please avoid. Buy an E3D v6.
