32PCS Mk8 Nozzles 3D Printer Extruder Nozzles Hardened Steel, Stainless Steel, Brass High Temperature Pointed Wear Resistant Nozzle 0.4mm,Compatible with CR-10, Ender 3/ V2 Ender3 pro,Prusa i3

Well I was hoping to not need these for a while and just have them at the ready just in case. Then suddenly I come home to a failed print and it would appear German Shepard hair in the print and a clogged nozzle....was it from the dog too??? I dont know what I do know is I pulled these out looked them over and swapped out the nozzle as soon as hot end was warmed enough. This was followed by a sigh of relief when the next print was flawless. Good job manufacturer!!!! When I get my all metal direct extruder I will likely get to try a few more before I get it dialed in. Bottom line, good price, great product buy without fear.

This was a really nice kit of assorted nozzles. I thought it was an assortment of brass and steel but it was various sizes as well which allowed me to discover a whole new world of printing. I love a .6 nozzle and would have never have intentionally tried/ordered a .6 nozzle. Not sure what other products this seller has to offer but I am very satisfied with this purchase. Happy Printing.

Nice kit that includes hardened nozzles for more abrasive filaments. I run wood infused PLA though them with no issues. Good price too!

The nozzle stem is too short, so the nozzle tightens flush against the face of the heater block before it makes a seal with the heatbreak inside. Because of this, the hotend oozes filament around the threads and out of the top and bottom, leading to clogs and failed prints.

I’ve expanded my horizons trying out all of the different sizes nozzles- some prints that don’t require a lot of detail are printing in half the time now feom usi mg the larger nozzles. Awesome!

Ive relied on a buddy who lives in the 3D printer world for advice and technical support. He quickly realized his call me any time offer when he suggested the ENder 3 pinter would come to haunt him. Ive had issues with the Ender that come down to the nozzles. Hes been over, cleaned and replaced nozzles and used all sorts of technical language that I pretended to understand, repeated back in the following sentences and did a lot of nodding. He then told me to watch him replace a nozzle and told me that this kit was what I needed. What I did not realize is that he was training me to be less reliant on him to fix my printer issues. With the kit in hand and him traveling for work, i had to replace a nozzle. Thanks to Google, I was able to determine the correct size and YouTube led me to videos that showed me how to do it for my printer. This kit had all I needed to change nozzles. The new nozzle worked better than the original and I was able to tell my mentor that the replacements viscosity coefficient was small. Im new to all of this but found this kit recommended by my mentor who works in the 3D printing field, had what was necessary to change nozzles and the new nozzle works well. Lots of options here.

Great Kit! I am not the greatest with knowing information with 3D printers but mine was clogging at first and now it works great. And I also thing I got some extras.

No matter what 3d printer you have, you will eventually need to replace the extruders as they wear or you encounter an issue. This kit provides a decent variety of steel and brass replacements in several sizes, so that you can adjust your extruder to both the type of filament and size of filament desired...some filaments are more abrasive than others and sometimes a wider filament does a better job depending on what you are printing. The extruders are reasonable well finished, and the interiors (where it matters) were smooth on the kit I received. The threads were clean and swapping out the extruders did not come with the feeling of imminent cross threading, which would have required replacing the heads.

When using the steel nozzles, there were a whole host of issues, most likely due to a difference in the hardness of the nozzle and the increased thermal resistance of steel, as a word of warning- if you are running a stock heating block - it may not be powerful enough to overcome the thermal resistance of the steel used

Good variety pack for a good price.
