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)

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

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.

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.

Leaves a very smooth top surface

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.

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.

I wanted to be able to print with whatever material is available, specifically carbon fiber and marble PLA. Because I’m new to the hobby, I figured a Diamond top would allow me to eliminate one variable when troubleshooting.

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.

This nozzle is awesome but can throw you for a loop in one regard. Much like steel nozzles it can change the temp needed to print but unlike steel you wont see a potential increase in temp but a potential decrease in it. Definitely worth the money in my opinion
