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

Product is as advertised and shipped well before it said it would. Be warned, this one DOES NOT FIT THE PREDATOR! The heartbreak on the Predator specific one is longer to work work the effector plate. Also, swap the PTFE to a higher temp one before you install it. It’s way easier that way.

I already messed up one print head by overtightening an extruder which resulted in it breaking off. I was not able to extract the remains with a screw extractor, so a spare print head comes in handy. Hopefully I will not need it, but you never know.

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).

A+ perfect fit

Forgot to check the size, came as .03mm, now I have them in case I want to change from 4s

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.

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

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.

Its the real deal

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