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)

So far it is mind blowing. There is so much good to say about the nozzle. First running at a lower temp is great and prints are much neater. Best though is after using many many rolls of various filaments the head still looks brand new and perfectly clean. I have tried so many different types of tips before and never have I had the results and ease of this nozzle. Well worth the cost and I have been telling all my printing friends about 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

Running a 3D printing business can be demanding on your printer's consumables, especially when printing abrasive materials constantly. Before I bought this nozzle, we were going through 2 - 3 hardened steel nozzles a month from printing mostly Carbon Fiber Polycarbonate and Carbon Fiber Nylon PA-6 / PA-12. This nozzle has lasted several months and through about 30kg of abrasive materials so far without any drop off in quality. The extrusions are consistent and clogging doesn't seem to be an issue whatsoever. If you're someone who prints abrasive materials often, this nozzle is definitely worth the upgrade!

When I bought my Ender 3 S1 Pro last year, before I even assembled it, I bought one of these polycrystalline diamond tipped nozzles because of the recommendation that Zack Freedman had made on his YouTube channel. The first thing I did after assembling my 3-D printer was to remove the stock nozzle and replace it with this one. I haven’t looked back since.Being new to the 3-D printing hobby, I did not know that glow-in-the-dark filaments were extremely abrasive, and could destroy a brass nozzle after only a few prints. This polycrystalline diamond nozzle handled it with aplomb. Not only did it handle the abrasive filament with no wear or damage whatsoever, it also managed to stay reasonably clean, since nothing seems to stick to it. There’s no need to add line to your printer’s G-code for the nozzle to run through a brush after each print.It extrudes filament beautifully since the thermal transfer of diamond is 543W/m-K, far superior to brass, tungsten carbide, and hardened steel.I expect it to outlast my printer, and when I get another printer to replace it, I’ll probably just install the same tip and keep printing.

Before I installed a Diamondback nozzle onto my Ender 3 Pro, it had some of the poorest temperature conductivity of any of my printers. A particular filament I constantly need to print is Overture brand light gray PETG, and my poor E3 could only succeed in printing that as high as 255 C, or else the extruder wheel would skip and make a horrible, nightmare-inducing knocking sound as it struggled to push the plastic through. Nuts.I installed a Diamondback, and printed a temperature tower in the same filament, and it succeeded without any flaws all the way down to 220. In fact, previously I had also turned down speed to guarantee first layer adhesion, but with the new nozzle, I started suffering heat creep. I was printing too slow. Now, I print at 225, a full 30 degrees lower, and I can print the first layer at 50% speed rather than 5%. This thing has been a saving grace, and I can print objects faster and prettier for my small business.I actually bought two and fitted my new Sovol SV01 Pro with it as well, but I got ahead of myself and started turning temperatures too low after my experience with the E3. Prints were failing or looking extremely flawed, and I thought I'd broken the printer somehow. Nope, just needed to turn the temperature back up about 10 degrees. It still prints a full 15 lower than expected for PETG, but, don't make my mistake. Just print the damn temperature tower. It wastes less filament than busting out ugly unextruded or overextruded failures. Every printer has it's own preferences.It's also a huge plus when you know that the nozzle will never flinch when printing abrasive materials. That polycrystalline diamond tip means you never have to replace it. I might come back to get another for my tiny little Ender 2 Pro, or if they release one that's compatible with Qiditech printers, but I'm not holding my breath since they're proprietary. But yeah, if they have a size that's compatible with your printer, do it. You might need to do some temperature and PID tuning afterward, but most likely you'll be able to print both faster and at lower temperatures. You won't look back.

Legit the best nozzle I have ever used. Nothing sticks to the tip and lays down buttery smooth. The heat coefficient is no joke you can dial your Temps back quite a bit. Just make sure your bed is level and z-offset is dialed in.... no forgiveness on build plates!

Delivery was very fast(1week) nozzle came in a steel container and was well protected. Prints came out very clean and smooth. Unable to judge how it stands up to abrasion, but after about 15 hours of glow in dark filament prints, still looks and prints exactly the same as when I first had it.

I found out about this product on 3d musketeers vidéos and after a couple of months I finally bought one. It's been a few days but I had no problem so far. The packaging is very well thought off and the nozzle is of great quality.

Was printing perfectly before installing this nozzle but have had nothing but headaches since. The nozzle oozes constantly despite reducing the temperature and everything sticks to it badly, creating terrible stringing and blobbing. Prints are practically unusable. Completely regret buying.

Bought this nozzle in the hopes that I can improve print quality and have a nozzle that'll last years. Since installing on my ender 5 plus I've had under extrusion and clogs. I've tried printing at higher Temps to no avail. Wish I could get my money back at this point.
