Creality K1/K1 Max/K1C/K1 SE Extruder with Motor, Official Upgraded K1 Extrusion Kit Direct Drive Extruder Dual Gear Smooth Feeding High Speed Printing Extruder for K1 SE/Ender 3 V3 Plus 3D Printer

This upgraded extruder made loading filament so much easier in my printer, its held up for another 300 prints with zero issues. I have done several prints at 1000mms just to test the quality of the extruder and i was blown away with how well it held up. This is the best option for your money.

Fixed my issue with the original one failing to properly feed, causing filament to get stuck in the hotend. I would probably be more upset but I did print a decent bit in the 8 months it lasted and its affordable at least. Not everyone sells replacement parts at decent prices (cough apple) so I can appreciate a company that doesn't tell me to pound sand when I need a part.

Great replacement part and very easy to install very happy so far no clogs.

Solved my extruder issue prints great now before and after pics

The stock extruder on my K1 started grinding filament after a few months of heavy use so I went with the official Creality replacement kit. It dropped right in with no fitment issues and the feeding is smooth and consistent now. The grinding and occasional skipping steps are completely gone. Not the cheapest fix but using a genuine kit means you know the tolerances are right.

Worked perfectly as a replacement part. My original part began to have issues at around 1600 hours. Turned out that a wire had pulled loose from the harness. Drop in replacement. Easy fix.

JUST WHAT MY NEPHEW NEEDED TO FIX HIS 3D PRINTER!

Yes yes yes! My k1 max wasn’t extruding. Bought this once I found my motor was bad. Popped right in, works great and my max has now printed 100 hours since purchase! I can stand on this review!

開封しようとしたらシールが切られていた 買う時に中古品の表記が一切無かった 使用した形跡がある商品が届いてガッカリ

Fit like a glove no issues but it squeaks so idk what to do

The motor connection is very weak. Few weeks after getting it, a small incident broke the wire. There's no connector so there is no way to fix it. Ordered another generic motor. The extruder also has a very bad standing for many of the pla I use. The material break in easily and I had breaks often. Changed to a full metal extruder, never jammed since. So basically, good enough for the price, but I would recommend going for higher end.
