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)

This thing changes the game! Don’t even waste your time with anything else, nothing is harder, hotter, or smother going in and out! (that’s what she said)

I got this nozzle as a luxury gift for myself and to help get my printer prepared for abrasive and high temp filaments. I am running it on an almost stock Ender 5 Pro with the Creality hot end (POLISI3D all metal heat break), but with an E-Fit Direct Drive mod, inside an enclosure tent. Pros: It does absolutely everything advertised. Manufactured and sold in the United States. Cons: It is pricy. Hardened version of the nozzle is still in development. They do not make versions for proprietary hot ends like the Creality Spider. So far I have ran cheap PLA, eSun PLA Pro, and JAYO TPU through this, as well as Amolen Dark Blue Glow in the Dark filament. The PLA came out pretty standard, although I did most of my prints at the low end of the manufacturers recommendations. Before I got this nozzle, I had a lot of problems with the Amolen filament due to the abrasiveness and viscosity of the filament. This nozzle alleviates many of those issues because the diamond conductivity and low friction coefficient really helps the flow. Each nozzle has a laser engraved serial number and a lifetime warranty. The metal nozzle case is neat, and so is the sticker. The 3DMusketeers interview with the US Synthetics design team was extremely informative. Found out from that video that the dark color of the nozzle tip is because the sintering process includes using cobalt to fuse the polycrystalline diamond. I really want more of these, but I only managed to get the .4mm nozzle thanks to a holiday gift card

A diamond nozzle, sounds silly. Sounds like Im going to get a nozzle that sparkles, sputters, and then proves to be just like every other nozzle. I was so happy to be wrong. This nozzle is exactly what it says it is, in an industry with very little accountability for claims made by manufactures. It is a lot of money for one nozzle. Buy it anyways. I havent had to buy a new nozzle in almost 8 months now. I ran this nozzle into my magnetic PEI sheet and gouged a canyon in it. The nozzle was unscathed. No jams, no clogs, and I still get the smoothest layers running at the lowest temperatures of any of my brass, plated, or hardened nozzles.

The nozzle has the best qualities in every category. Thermal conduction is fantastic. The polished, small end squishes the filament bead perfectly and just glides over the lay down. The price is $$$, but the old saying- you get what you pay for definitely applies. Longevity is next, but that is unknown, but being diamond, I would assume very long. Love it!!

Make sure the threaded section matches you current nozzles. It was too short for my Ender 5 S1 and caused it to get clogged.

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.

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

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.

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.

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.
