Diamondback Nozzles – MK8 Compatible – Polycrystalline Solid Diamond Tip 3D Printer Nozzles, Improved Extrusion, Any Filament, Long Life, Wear Resistant, Layer Adhesion, USA Made (0.4mm)

Leaves a very smooth top surface

Nozzle kept clogging despite the companys claims that the diamond insert made this impossible. Swapped it out with a hardened steel nozzle so I could get back to work. Not worth the price.

I’ve been using their other offering on my all metal e3d v6, but my Creatbot F430 hasn’t gotten the same treatment. That’s all changed now, and the wait has been worth it. Beautiful prints, my only wish is it went up to 500c so I could use it for PEEK.

All I can say is wow this nozzle prints absolutely perfectly. I have a Voxelab Aquila (Ender 3 v2 clone) with Ender Sprite DD extruder and the MK8 version of this nozzle works perfectly. Seems like nothing sticks to the nozzle and prints are silky smooth. Nozzle is not cheap but way worth it IMO.

Installed in the QIDI I-Fast standard extruder, adjusting the tempts took some time to dial in, but once adjusted, works great

I dont have the skill set to verify their claims.... But I absolutely love the nozzle, it works amazingly with everything Im throwing at it.

The Diamond end delivers the heat all the way to the tip. Typically, you have a higher internal heat with the tip being colder. The high thermal conductivity lets the heat to be delivered to the tip letting you drop your internal temperatures. The polished end make for some beautiful ironing moves. Im using this 0.8mm on a volcano head and made a gold plated copper core to act as an insert adapter. Easily running >40mm^2/sec (still pushing it higher in testing). Use this machine for printing equipment boxes to hold components, covers, etc.. It is a big machine and needed to push some material accurately.

Maybe i received a bad 0.4 mk8 nozzle or not sure but im having A LOT OF STRINGING problems in different prints and some defects. I tried multiple Filaments (brand new and sealed), and i keep having the same problem. I tried different profile settings. The only reason i purchase this nozzle was for hoping to even improve the quality of my prints but this is clearly not the case. Im having way better results with a simple brass or Hardened steel nozzle. The only reason i give it two stars is because the parts are still usable, otherwise one star.

Worth the price? Maybe? Honestly I just got tired of installing new cheap nozzles after the softer ones would degrade and ruin my prints :P

I dont give 5 star reviews, but this nozzle has done nothing but perform, and is working flawlessly for a couple of weeks now. Diamondback nozzles are the way to go in my book for now on.
