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

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

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.

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.

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.

It works awesome on my Neptune 3 Pro. The best thing about this nozzle is filament will not stick to the diamond.

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.

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
