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

The nozzles are exactly what you would expect. They are brass, they are cheap. Youll run through them like any brass nozzles. The reason I am giving this 5 stars is because the wrench that comes with it is an unexpected highlight. It is far better than the little wrenches that come with every printer I have owned.

I never could get my ender 3 Pro to print with the steel nozzles.

This is a handy mix of nozzles in the most common sizes. The hardend steel is particularly useful for slightly abrasive filaments. It would be nice if the pack had 0.6 and 0.8 in the hardend as well, but for most people this set has all you need.

Ever since I got these I thought something had gone wrong with my printer. No amount of adjustments would help. Regardless of whether the steel or the brass, the prints would always come out awful. I started noticing that when I did get good prints, it was from old nozzles I had. Finally I started testing these nozzles with the same configuration against others I had of the same size (the only difference was making sure the bed was leveled each time.) Without exception I had great prints with other nozzles and awful with these.

Good variety pack for a good price.

A++++

These are pretty nice nozzles look forward to use some carbon fiber pla with the hardened steel ones.

While the product comes with ample replacement nozzles and needles, the quality of the individual parts is poor. I feel as though they have to include a larger amount of items to make up for the lack of quality. The nozzles seems to be the proper size, but they clog incredibly easily and produce poor quality prints with no smoothness to them. In the image, it was a stainless steel nozzle used with black PLA that got incredibly clogged and made the print quality worse on top of the rough extrusion. I ended up switching back to my slightly abraded Creality brass nozzle and got a higher-quality print without changing any settings. The only thing about this product that was worth paying for were the needles.

Got what I asked for, my printer was acting crazy bubbling all my plastic figured it was a jammed nozzle put on one of these new ones and bam problem fixed.

I watch a lot of videos and read a lot regarding 3D printing, but I just dont see that much discussion of nozzles. First of all, nozzles are consumable. Especially brass nozzles. These nozzles last a while but do have to be replaced. This is especially dependent on the filaments that you are using. Many filaments that contain extra ingredients such as glitter or wood fiber, will put more wear on your nozzle and require you to change it more frequently. So have an assortment of extra nozzles on hand and swap out your nozzle when you start seeing issues. This kit is a great start. A good assortment of nozzles. Not only brass but all stainless steel and hardened steel. With this assortment, youll be set for quite a while. The cleaning needles will help prolong the life of your nozzles as well. Taking a nozzle off for cleaning or swapping in a new nozzle is really simple. These nozzles appear to be of good quality and so far Ive had no issues. It is a good price for a good collection of nozzles. This is an essential item for your 3d printing tool kit.
