Creality Official Upgrade K1 SE/K1C Extruder, 50N Strong Extrusion Force & Dual Gear Design Provide Smooth and Precise Feeding，OEM Replacement Parts

Review: Creality K1 Extruder Upgrade – A Must-Have Enhancement Upgrading the Creality K1 with this new extruder has been a transformative experience for my 3D printing workflow. Right out of the box, it was clear that this extruder was engineered with precision and reliability in mind. Performance The upgrade immediately resolved the occasional inconsistencies I faced with the stock extruder. With better filament grip and smoother feed control, prints now come out with sharper details and fewer layer issues. Whether working with PLA, PETG, or even flexible filaments like TPU, this extruder handled them all with ease. Ease of Installation Installation was straightforward, taking about 20-30 minutes. The instructions were clear, and the components fit perfectly with the Creality K1’s design, making the upgrade process hassle-free. Results What stands out most is the improvement in print quality. Layer adhesion is noticeably better, and the overall precision has increased, even on more intricate designs. The reduced clogging and under-extrusion mean I can leave longer prints unattended with confidence. Why I Love It This extruder upgrade has breathed new life into my Creality K1. It’s not just an enhancement—it feels like a complete performance overhaul. For someone who focuses on intricate, customer-designed devices and articulated miniatures, the difference is night and day. My print success rate has significantly improved, and the time I save on reprints alone makes this investment worth every penny. Verdict If you’re serious about getting the best out of your Creality K1, this extruder upgrade is a no-brainer. It’s a solid, reliable addition that turns a good printer into an exceptional one. Highly recommended!

Improved extruding. Easy to install. Worth the rather low cost of upgrade.

My initial release K1 had all of the typical issues with the hotend and extruder that you could find everywhere online. I think the primary detractor to this extruder design is the PTFE tube that comes out of the bottom of it and butts up to the hotend. I think more of the extrusion issues are related to the PTFE tube not being fully aligned to the hotend. I paired this new style extruder with the Unicorn hotend found on the K1C and I couldn't be happier. This allowed me to get rid of that PTFE tube from the bottom of extruder and run the hotend directly into it. This pairing immediately solved my under extrusion issues and my K1 now prints beautifully.

It extrudes better than the last one when it encountered a waterlogged filament that broke off and jammed. My prints are good and it fits the machine well. Definitely worth getting to keep your machine operating!

This extruder is a piece of junk. Buy the original instead! I think people have hyped it up before actually testing it, because it didn't take long for it to fail on me. The plastic gear that connects to the filament-gripping u-wheel started slipping! The gears turn but they won't push the filament anymore because they're sliding on their own shaft! I'm very disappointed, clearly a lot of thought was put into this extruder, but it looks like they didn't even bother to glue the gears on, they're just slid on there. I returned it and got another unit and it did the exact same thing. If they had just made the gears out of steel and threw some loctite 638 on it this wouldn't have happened. When the extruder did work, it did in fact print much nicer than the original and eliminated VFA, but that means nothing if it breaks after 2 prints! I can easily separate the gear using a pair of pliers on this thing. Compare that to the original, which I couldn't remove even using all my strength. I tried supergluing it back on, but that didn't work.

Perfect fit, easy installation, came faster then if I ordered from the company,

Easy to install

Factory replacement part, excellent price, fit is perfect and original. Easy to install even without instructions. No issues with print quality afterwards, it cleared up the filament jamming issue I was having with the worn out part it replaced.
