Creality K1/K1 Max/K1C Extruder Without Motor, Upgrade K1 Max Extrusion Kit High Speed Direct Drive Extruder Dual Gear Feeding Extrusion Mechanism Kit for Ender 3 V3/Ender 3 V3 Plus/K1 SE

great product

I’ve had two Creality K1 printers, and after using the K1 Upgraded Extruder on both, I can confidently say it’s a solid improvement over the stock setup. If you’re running into inconsistent extrusion, filament grinding, or just want better performance, this upgrade is worth considering.Installation is pretty straightforward—it’s essentially a drop-in replacement for the original extruder, and Creality includes everything you need. Once installed, the difference is noticeable. Filament grip is stronger, reducing under-extrusion issues, and retractions feel snappier, which helps cut down on stringing. It also handles flexibles and abrasive filaments better than the stock unit, making the K1 more versatile.One of the best things about this upgrade is its increased durability. The stock extruder on the K1 works fine for standard filaments, but it tends to wear out quicker, especially with higher-speed printing. This upgraded version holds up better over time, giving you more consistent prints without needing constant adjustments.If you’re pushing your K1 to its limits or just want a more reliable, hassle-free extruder, this is a must-have upgrade. I’ve got them on both of my K1s, and they’ve made a noticeable difference in print quality and reliability. Definitely worth the upgrade!

Work as it should. Love it just got replace my bed and I'll be printing again. It tuff when buy a k1 and just say I'll print it my self whew was I wrong 7 month and only 2 successful print and one was the tiny boat. But the feed replacement is way better than factory one

Somewhat flimsy. Design of the gears look pretty solid otherwise.

Easy replacement for broken parts in a 3d printer. Cheap and simple to install.

I needed to replace an original extruder on a K1. This does the job perfectly.

My Creality k1 has been working flawlessly for months, and all of a sudden not one print would come out correct. The biggest problem was my printer was skipping groups of layers throughout the print, most noticeably on the first few layers. I first replaced the hot end thinking it may have been that. That didn't solve the problem. I then remembered that creality has had ALOT of problems with their hotends and extruders in their early models of the k1, so decided to try this. Just holding the two in both hands i could tell it was going to solve the problem, and it did! My printer is back up and ripping at full speed without any problems. If you're having layer problems and find out you have an older version of the extruder i would put money on this solving the problem.

I started a print one day on my K1 and came back to find what appeared to be a colossal dinosaur poo wrapped around the extruder, housing and everything. I guess the filament somehow went sideways and it was a nightmare. Using a heat gun, I was able to carefully remove the clump of filament and damaged extruder parts.Once this extruder arrived, I removed the old one. ***Note, carefully place your screws someplace safe because they tend to jump and land in very dark places*** Installed this one and bam, back in business. No issues since.I'm not very nerdy about 3D printing parts and accessories but this thing does the job.
