[Sintron] 3D Printer MK8 Extruder hotend 0.4mm Nozzle Latest Upgrade Print Head for 3D Printer Reprap Mendel MakerBot, Prusa i3 & rework (3D-MK8)

Overview:

The extruder is almost the most important part for 3D printer, also the most difficult part to calibrate. we have made necessary design to prevent “jammed” problem. I can’t emphasize anymore how important this is, other sellers don’t have this and would cause many problems.

Features:

(1)The extrude is with thermistor sensor.
(2)Compatible with ABS and PLA 1.75mm.

Tips:

While using with PLA filament, please always remember to keep the fan on, otherwise it might get jammed and ruin the hotend. PLA is more easier to get jammed, so it might require some patience to practice.
For ABS, we would also suggest to keep the fan on, as this is also better. also remember to purchase filament from good reputation seller, as the filament is very important!

  1. Worked great from day 1, no issues at all. This is my first hotend purchase since I am just getting into 3D printing. Read a lot of reviews and decided to get this one. Was not disappointed. Came fully assembled and has worked right since I installed it. It has never jammed the filament once in the weeks I have been using it. The only complaint I have is that it can be hard to refeed the filament when I accidentally retract it too far, but that’s only because of how I have it mounted on my frankenprinter, so not the fault of the…

It does not come with a push-fit connector to…
