k1 Max Extruder Upgrade xirbbo 2Pcs Motor Extruder Gears k1 Max All Metal Filament Drive Extruder Gears for Creality K1 / K1 Max / K1C Nickel Plated Hardened Steel Plating 3D Printer Accessories Parts

I finally got around to adding these gears to my extruder. They seem to be working great and i don't have to worry about them getting damaged.

I upgraded to the Xirbbo Extruder Gears (Nickel-Plated Hardened Steel) for my K1 Max, and it made a huge difference! The installation was straightforward, and it immediately resolved my extruder issues. The build quality is excellent, and the hardened steel ensures durability. If you're having problems with your stock extruder, this is a must-have upgrade!

A great replacement on my Creality K1C. The exchange was very straight forward with a little mechanical knowledge. So far this has done well for multiple prints, except with TPU filament, which may not even be the feeders fault

First off let me start this review by saying I may have gotten a bad set, it happens, but being as that may I will be reviewing the set I got.I installed these on my K1 Max as I was starting to get more into TPU printing and had read that switching to all metal gears had helped another user's prints. However I also bought a second extruder just in case as I had also seen the review of it destroying someone's extruder. Well first thing I noticed was it was a lot easier to guide the filament down into the nozzle when loading.......that honestly should have been my first clue of the issue to come.I started a flow test to see how it preformed at a temp and speed I know the unmodified extruder could print at and had to stop before the first layer was done due to massive extrusion issues with it underextruding like crazy on chips that the original one printed just fine. Increased the temp by 10 and then by 20 and same thing.Switched over to the new extruder, which was harder to get the filament loaded, and ran the test from before with the known good temp. Printing just fine, my running theory is that the gears have a bigger gap making it so it's not applying the correct tension. Again could have been the set I got but definitely think before buying.

These all-metal extruder gears feel much stronger and more durable than the stock plastic ones that come with the Creality Ender 3 V3. I wasn’t having any major issues with the original gears, but I also haven’t been printing with the machine for very long and have only used PLA so far.Swapping out the gears was pretty straightforward and didn’t take much time. I didn’t notice any dramatic difference in print quality after the upgrade, but I have no doubt that these metal gears will last far longer and handle tougher filaments better than the old plastic ones. Definitely worth considering if you want a more bulletproof setup.

On my K1c, I was having a problem with my first layer. small blobs would appear causing the model to dislodge from the bed, After replacing the gears, the problem was gone. worked so well, I bought another set for my K1.Very happy with the results.

Purchase this upgrade for your printer. I have the K1 max and about 2 weeks after getting it a generic filament got stuck and people my extruder gear. After that I purchased this one and it’s made such a would have difference on my prints. My prints are smooth consistent.This is what you need in your life, make your printing confidence increase.
