Diamondback Nozzles – V6 Compatible – Polycrystalline Solid Diamond Tip 3D Printer Nozzles, Improved Extrusion, Any Filament, Long Life, Wear Resistant, USA Made (Brass) (0.25mm)

I'm using a 0.4 nozzle for everything. I get such good prints with PLA, that it is worth buying for that alone. Of course the incentive for getting it was nozzle hardness. That it delivers on that goes without saying.When I ordered it, due to a lapse in attention or something I ordered the 0.4 instead of 0.6. Over the last year I've printed the equivalent more than 2 spools of carbon fiber consisting of PLA, PETG, ASA, and PC from 5 different manufacturers. All of them chopped, not ground fiber. So far zero, 0, clogs! I'm not 'recommending 0.4 over 0.6 nozzles with carbon fiber but I seem to be getting away with it.I've had one rather bad head crash which it survived undamaged. Also although the brass part of the nozzle has gotten gunked up on occasion, the diamond portion remains clean.The price is eye-watering (wallet-watering?) but if you can get it on sale as I did, jump on it.Note: if you're new to 3d printing, maybe hold off. When you're new and perhaps don't have the best printer, you can have a lot of accidents that it might not survive. Also it would be a waste of money if you find fdm printing isn't for you.

I've been 3D printing for a few years. Over this time I've done countless upgrades to my trusty old ender3. Of all of the upgrades I've done, none have made a bigger impact than this nozzle.I can't rave enough about how much this has improved my print quality and consistency. The reliability alone has made me a lifelong customer. Is it expensive? Yup. But the time I've saved is worth the price.Before buying this I felt like dealing with clogs and nozzle replacements was just a necessary evil. Having to pull off the tool head and clean it all up was a pain that I just thought was the norm. But in the 4 months I've had this thing I haven't had to touch my toolhead once. No clogs, nothing. I've been pushing ABS, ASA, PETG, and even some carbon fiber PETG, all of which have printed perfectly. I seriously couldn't ask for a better upgrade.

Alright. So I've tried a good swath of nozzles through my modified Ender 3 and most have been suitable but I wanted something I could just leave in without having to adjust for the different temperatures of hardened steel or the softness of copper nozzles. Had a Vandium and Bridgemaster from Slice Engineering and while both were fantastic, they just didn't fit with what I needed.Found this nozzle a few weeks ago and sat on it for a while. Reached out to their customer service with some questions and they were more than helpful. But the bullet and bought it. I can confirm that this was the right choice.Without optimizing the profiles for this nozzle prints already come out super clean aside from the top layers, and this is the first nozzle I've ever had that actually doesn't have anything stuck to it's tip. The polished surface of the diamond tip makes layers go down extra smooth, and it shows when it prints. Temperatures are stable and the quality of construction is fantastic of course.(When looking at the picture of the cubes listed from left to right)Did some test cubes with PLA, Wood Fill, TPU, Silk PLA, Carbon Fiber PETG, Glow in the dark PLA, and Regular PETG. Every single one print d fantastic aside from adjustments I need to make in my slicer for this new nozzle. I'm honestly shocked. if you're on the fence about this nozzle, do it. You will not regret it. This is a premium part that offers premium results and one to the very few that I've rated on Amazon giving it 5 stars. SIMPLY SUPERB!Update:8/11/2022This thing is still working flawlessly. Have put about 2 kg of carbon fiber PETG through it without issue. One thing to note is to NOT USE A WIRE BRUSH WHEN CLEANING! If a fiber gets caught within the nozzle and gets bent, it can put pressure on the polished diamond edge and break a small sliver off. Didn't happen to me, but happened to a friend. Just use a junk rag to wipe off the nozzle. Do this and it'll last for for a long time to come!

I love this thing. Before this, my best nozzle was a long volcano style ruby clone I paid 45 bucks for. You can debate all you want on what you really need for abrasive materials. All I know is I print in lots of stuff so the nozzle has to also do PLA and PETG well. Most of the other options like hardened steel or e3d's wonder nozzle mess up bad on petg and leave weird artifacts on PLA because of it sticking to the nozzle. You don't have this problem with diamond or ruby, and you are good to 300F. So you can waste your money on CF-NL you probably don't need. What I know is, even if I'm printing polyterra (I usually am now) I'm going to destroy any all brass nozzle within six months. Just with PLA. People don't understand that those silks and woods and just some dyes in PLA will erode brass nozzle openings. Silks are the worst. How do you think they get them to shine like that? It's not as bad as CF but it is still abrasive. So I just want to never have to replace this part again, and I want good finish on my prints. You get that with this nozzle. Things don't stick to it. It doesn't wear out. I have put a bunch of CF-PLA and CF-ASA through it, then gone right back to cheap polyterra. No changes. I printed enough CF that I'd have ruined a cheap plated brass nozzle. I'd have gotten through the nickle. I'd have started to wear on a steel one. This one is just like the first print. Every single time. So don't buy this just because you want to print exotic materials. It's an upgrade for simple PLA. You get a better surface finish than you will with any all brass nozzle. This thing is expensive, but it goes above and beyond what you are expecting from it. If they made it in the longer volcano size I'd have two of them.
