In this video, I'm sharing with you my findings after putting a high quality $100 Diamondback nozzle under a microscope to see how good they are.
After testing a bunch of different nozzles, I found that the Diamondback nozzles were the best quality out of all of them. I strongly recommend you invest in a set of these bad boys if you're looking for a quality brass nozzle!

Thank you so much for this detailed microscope analysis! I'd bought a Diamondback nozzle and fitted it, but I've been having issues with rippling on surfaces that I was utterly unable to dial-out. I even had to drop my flow rate multipliers down to 0.8 just to get prints to be somewhat decent, and even then for large surfaces I had to drop it as low as 0.75x at times. Basically it's behaving like if printing with a severely worn nozzle.
Your microscope shot of the stock 0.4mm nozzles next to the 0.4mm Diamondback nozzle gave me the answer. I took a still frame of your image and compared the diameter between the two nozzles by counting the number of pixels across the orifice diameter. The Diamondback Nozzle came out to 15% more pixels/diameter than the brass nozzles, and then suddenly everything made sense after I found forum discussions of people resolving issues of rippling/pillowing due to nozzles being worn and having a larger than normal diameter.
I went back into the extruder settings in the slicer, and set the nozzle diameter to 0.46mm (So 0.4mm + 15%) and made all line widths be a relative percentage of the nozzle diameter (100-125% depending on the line type). After performing (yet) another flow re-calibration test everything is now printing as it should be and the uncontrollable rippling has gone away.
So, once again, I thank you for this analysis. You've helped me to find out what was going wrong at my end. I wonder if the US Synthetics crew are aware that they're shipping nozzles that are larger than advertised and the issues that this can cause customers who don't compensate for that in their settings. My experience with dealing with these issues has somewhat soured my initial excitement with the nozzle as I've spent about two weeks now and 2 rolls of filament trying to isolate the issue and restore print quality back to what I was getting with the hardened steel nozzle I was using before.
This legitimately might be one of the most detailed analysis driven comments Ive received to date. I love this comment and Im even more excited that I was able to solve your problem. Now I wonder this, what if they are shipping nozzles with the correct diameter and the cheap brass nozzles are shipping poorly specced nozzles yet all profiles in cura, prusa, etc. are dialed into the incorrectly sized nozzles. That seems like a very real possibility.....or well...maybe it's just me play devils advocate. In either case, Im very excited I helped you out because this is definitely not a video you'll find elsewhere and you wouldnt have been able to see that yourself with any camera! Hopefully the diamond back works well for you now!!! :D

I prefer Occam's Razor here to reason out what's going on. There are many manufacturers of nozzles. It is known that worn nozzles start to produce bad results and require lower flow multipliers to continue to produce anything somewhat decent.
Cura has its default extrusion width typically set to 0.42mm. We can surmise that this is to compensate for small variations in nozzle diameter. It's easy for a smaller diameter nozzle to act like a larger one by pushing more filament through per mm traveled. For example, a number of flow rate tests use a 0.75mm extrusion line width with 0.4mm nozzles. It's much harder to make a large nozzle act like a small one. How do we ensure that the filament only comes out the center and not to the sides and thereby producing a line that has inconsistent edges.
If we think of it like using paintbrushes, it's easy to use a small brush to look like a bigger brush, but not the other way around.
I've used perhaps a dozen nozzles from different makers, including reputable brands. I've always been able to dial them in to print well just by tweaking the flow multiplier a small amount. The Diamondback is the only one I've used that gave me this much trouble, and especially so when asked to print 0.4mm width lines like Prusa Slicer defaults to for the top layer.
Occam's Razor says either the rest of the world is wrong (barring truly bad exceptions), or that Diamondback has slightly larger nozzle diameters, especially when under a microscope confirms such to be so.
On top of this, after setting the nozzle diameter to 0.46mm in the slicer, the flow rate multiplier is now back to the same sort of levels as every other nozzle. If it looks, walks, swims and quacks like a duck, it's almost guaranteed to be a duck.
Bought the Diamondback 0.4 along with my Ender 3 S1 Pro. Never bothered with any of the stock nozzles. It's been the best investment I've made for my printer; consistent and has never given me any reason to question its quality. Being able to focus on other things that affect print quality has really flattened the learning curve since I don't have to be concerned about the quality of the nozzle. ChampionX manufactures and uses their own nozzles in their factory in Ogden and have a long history of using polycrystalline diamond in a variety of industries. I strongly recommend their nozzles.
Have you looked at copper nozzles with hardened coating? There are multiple manufacturers. The selling points are copper has better heat transfer so you can run hotend temps lower while the hardened coating allows you to print abrasives without a nozzle swap. I tried one of the ez flow nozzles from TH3D and after a few weeks of use replaced my steel microswiss nozzles with these. I imagine most manufacture nozzles perform similar, and the hardened coating also is pretty nonstick so cuts down on filament clinging. I paid $14.99 each for mine but I believe they range from $15-$30 from most companies that handle them.
I have not done much experimentation with nozzles other than basic brass and hardened steel. I've used high flow cht nozzles, but in terms of material, no i have not experimented much. After this I'm seriously considering branching out to really check many brands/materials for performance and quality. I've had these diamondback sitting around for months and I'm about to finally get one of them loaded up. I want to dump a few kg of CF through them to check the degradation.
Will you do any more videos with this nozzle, showing off print quality and any tuning you had to do to temps/speed?
Yes I absolutely will! I have 2kg of CF on order and will run 1 through a standard nozzle and one through the diamond back then check the results. I will also do other tests!! :)
@@ThePrintHouse Awesome, can't wait!
link to miroscope?
Love your content you inspired me to start 3d printing!
Seriously? That's amazing!! I hope you enjoy the content!!
What's the microscope you're using?
This is the beaver labs microscope! It is reallly nice!! Works very well and reliable. The app is janky but I dont use it often, so it works for my purposes!
I believe there's a tiny chamfer at the tip of the exit of the nozzle, so the hole looks a little bit bigger than it is due to the reflection of the top surface. The best thing to do is probably to have a reference to actually measure the hole diameter other than purely using visuals.
Yeah that could be very true. From my perspective it was just to see the quality of the nozzle rather than get an accurate measurement, but now I'm interested in getting a measurement 😅
I hear the .4 is actually a .45-.46
Please send me an MK8 diamondback nozzle
I would love to work a deal out with diamondback. I might try!!
Wow that diamondback looks messy inside. It’s definitely not worth $100. Thanks for sharing this truth with us! 👍
