This is an modified MK8 extruder, which features outstanding quality and ensures better performance for 3D printers. Compared with the previous version, there are some differences on design of this new extruder. The feeding device of this MK8 extruder uses double “V” design which can ensure stable and constant feeding, and such design is much more convenient for you to load the filament right to the end of the barrel. The heat-resisting PTFE tube inside the barrel ensures fluent feeding and helps avoid blocking problem thanks to its self-lubricity. The brass nozzle ensures accurate extrusion, realizing excellent printing effect.

By simply adding an extruder holder, you can use it on most 3D printers such as Reprap Prusa I3 and many other types of 3D printers.

    Hi, after tons of satisfactory printing I have problems of feeding, probably clogging. I believe is the barrel of the hot end, the internal PTFE pipe became one with the filament......where can I find a spare of the barrel? Thanks and regards Maurizio

    • Jocelin Jia | 11/28/2018

      yes, it works. can you tell which additional parts you needed? may i have the specification?

      • Michael Kartner | 11/28/2018

        The small brass gear that advances the Filament (mounted to the shaft of the stepper motor). Mine has a developed a groove from heavy usage so that the Filament starts slipping.

    Hello, the pulley in the MK8 is made with aluminium? Thanks

    • Jocelin Jia | 06/23/2018

  • Jean-Christophe SALMON | 02/07/2018

    The MK8 extruder I have on my Prusa i3 Pro B does not work correctly anymore. I experienced problems, and thought the source was a bad connection. So I soldered the wires directly on the motor pins. But after a while, I still have problems : the extruder motor's speed is too slow and too little filament is extruded. I hope the problem comes from the extruder or cable, if I still have the problem with the new extruder I ordered, I'll ask you to send me a new GT2560 card (still under guarantee). Thanks for your answer JC

    • Jocelin Jia | 03/15/2018

      Hi Jean,sorry for late reply.Could please email to me:jocelin.jia@geeetech.cn,I will resend you replacement and please feel free to contact me if you have any problems.Thanks

  • kamil oliwer | 02/10/2017

    Hello, Is it possible to order RIGHT extruder? I Have PI3B (single left extruder) and would like to upgrade to dual extruder. I have geeetech gt2560 MB and free space for thermistor, stepstick, and stepper engine. Is it possible to make such upgrade? Greetings from Poland!

    • Zina Luo | 02/13/2017

      hello,this one is the short distance right hand extruder .

  • Timothy Good | 12/28/2016

    is the tension spring for this unit available separately? The spring on my i3 is beginning to weaken and the filament was starting to slip. I did a complete tear down of extruder and replaced nozzle and worn out tube, but filament would still slip. I inserted a washer under the spring which restored performance.

  • David Hannaford | 12/01/2016

    I have a Geeetech mecreator original model. Will this extruder head fit it OK? Does it have the same amount of heating in it. As I often get print failures at present due to the head temperature dropping too low when printing, after the first 5 or 6 layers being done OK.

    • rita xiang | 12/04/2016

      hello David, this extruder can me mounted on your printer. The two extruder use the same heater. If the extruder failed to extrude for the first 5-6 layers, you can add a brim or skirt to the printing model.

  • Samuel Bishop | 09/08/2016

    Just bought one of these and I can say it's a much better design than the original one. I've had to screw a heat sink onto the barrel/throat to keep it really cool but otherwise not a bad upgrade from the Mk 1.

  • Momme Krahn | 06/21/2016

    Can you please provide specifics of the gear used - is it the same MK8 gear? can you please provide number of teeth, outer diameter and hobbed / effective diameter? Thx!

    • rita xiang | 06/23/2016

      yes, the same with this one http://www.geeetech.com/mk8-drive-gear-p-990.html, teeth number is 35
