This tracks with what I've observed over the years: -Cheap nozzles generally work fine unless the aperture diameter is drastically off. -Cheap nozzles are inherently more disposable compared to quality nozzles because they don't resist wear over time, in addition to not feeling bad about junking inexpensive nozzles. -All dimensions on cheap nozzles are suspect, including internals. Avoiding either high or low extremes on flow rate and line width covers up some of the deficiencies, but print quality can suffer when diameters are well out of tolerance. -The overall cost of using cheap nozzles can be fairly balanced with using nicer (E3D, genuine Prusa, Micro-Swiss) brands - they get replaced more often but the lower unit cost offsets the replacement rate. There's something to be said for hanging onto older nozzles for prints using larger line widths, but I don't know how that would work well, short of measuring the nozzle diameter over time (requiring measurement tools, calibrations for those measurement tools, and a healthy dose of giving a crap) and adjusting line widths in the slicer to account for those changes. The time invested in keeping records on the diameters of your nozzles - especially if you have more than one printer or jump around from size to size or from hardened nozzles back to brass - starts to be worth more than the nozzles are anyway. It's no surprise that 0.2 mm nozzles suffer from the greatest variation...it's hard to drill small holes, thousands of times a day, and do so precisely and consistently. I would think that the high-end nozzle manufacturers, who have better Swiss machines, better machinists, and more robust QA, would be better at this - and again, that's been my experience. 0.2 mm nozzles from no-name Chinese Amazon listings are hit-or miss, the handful I've needed to buy from Micro-Swiss have been generally good. Also, I am a "metalologist" (metallurgical engineer), and you are mostly right about brass. Lead as an element doesn't actually have a ton of solubility in copper alloys at room temperature, and when that material solidifies the lead stays liquid for a fairly long time (C36000 free-machining brass as a whole solidifies at 1,630˚ in freedom units but the 2.5-3.0% lead by weight in the alloy will stay liquid down to 621˚) and tends to end up as little nodules; these nodules help break up the chips during machining and lubricate the cutting tools, which is why leaded brasses have been so popular for machining applications for so many decades. I wouldn't use the word "amalgam," however, as that is a term specific to alloys of mercury and any metal elements not named iron, platinum, tungsten, or I believe tantalum. To me, the concern about tiny chips of brass nozzle material in the plastic leaching heavy metals into food is frankly pretty minor, especially if you live anywhere near a coal power plant or other source of heavy metal air/water pollution...however, people considering using 3D prints for food/medical/[redacted] applications should be far more concerned about microbes collecting in the layer lines. Most hobbyist-level 3D printing filaments cannot withstand thermal sterilization processes like using an autoclave, and nobody in their right mind would print a [water glass and totally not a personal pleasure device] out of PEEK or PPSU. Most filaments popular with hobbyists will even struggle with a thermal/chemical sanitization process like using a dishwasher or purely chemical sanitization by way of a bleach solution (PETG being a possible exception due to its robust chemical resistance), and do you really want to soak your 3D printed dishes in bleach before later scrubbing them with soap and hot water? Pontificating aside, I very much look forward to part 3. The concept of the Diamondback nozzle, with the thermal benefits as well as stupendous wear resistance, is very attractive to me and one of those will be the next nozzle I get for my SV06+...I have too many cheap nozzles for my Ender 3 to justify getting a Diamondback for that any time soon.

@@madmatrac "Much more versatile in terms of heat transfer"...that's not based in science. WC has a thermal conductivity of 110 W/M-k and diamond is over 2,000, so even though WC's heat capacity is higher (just under 40 vs around 6.5) the thermal diffusivity of WC is still poorer than diamond. Also, I definitely would harden 416 stainless steel (after machining) for use in nozzle applications. It'd be a vacuum HT to preserve the surface finish, but a 13 bar nitrogen quench followed by a temper at 750˚F strikes a nice balance between hardness (and therefore wear resistance) and toughness.

When you showed the prints where one of them had more stringing, I immediately thought cheap nozzle (which as you said correlates with inaccurate nozzle size). In the past, when one of my nozzles got worn down, it always increased stringing. After switching over to Obxidian nozzles, I haven’t experienced stringing in 6 months. The new generation of wear resistant and thermally conductive nozzles has been an incredible boon.

Seasonal changes in temp/humidity play a much larger factor than you would think. I am not saying that your results are invalid, but I have had nozzles that worked for everything but either summer, or winter usually. Tungsten in a hot or humid environment doesn't work well at all, and cht clones can get weird/extra bubbly during winter or in high humidity. I think obxidian are usually worse in summer, and diamond is worse in high humidity given their material properties.

I think any light damage to the end of a brass nozzle could be fixed with a drill press. A while back, I got a variety pack of cheap nozzles off amazon. When they arrived, I noticed the very tip of them didn't have much of a flat on them. In order to fix that, I picked some of the best looking ones and chucked them up in my drill press, turned it on and pressed them into some sandpaper repeatedly. When I was finished, the sandpaper looked like it had a bunch of little dots on it, but all the nozzles had nice flat on them.

So i have a toy microscope... for kids... little handheld pocket one... purchased it in the 80s for the price of 7.90 Soviet Roubles, which i know because the price is moulded into the carry case, my memory isn't that good. It has an integrated scale etched into a piece of glass embedded in the cover, so you can measure small things. So i did measure my nozzles. They do come out correctly sized, the ones i do have. The microscope also has an integrated incandescent side light, and is specified to have 30x magnification. I hear you can get a piece of glass, i don't know if it's maybe a microscope slide or something, with a scale like that etched into it. If you hold it with the etched side onto your subject, you shouldn't have much trouble reading the size. Also i bought a cheap and spectacularly nastily made microscope attachment for a phone. It was one dollar shipped. It's just a single plastic lens, an LED, and a coin cell holder, with an automatic switch that turns the LED on when you put it on, but i have had success making nozzle photos with it, which i had done when i nickel plated the nozzle. The nozzle opening has reduced slightly but visibly from plating, but i don't remember whether i concluded it from looking at the nozzle purely from microscope photos, or from looking at it with the scale of the toy microscope. The photos are sort of ugly but you can see the nozzle surface and opening clearly. I should take the nozzle off now and see what it looks like. I do have extra nozzles, i mean they're so cheap. But i haven't plated them yet. I don't know if i want to, i can't make up my mind whether it actually helps anything. Maybe i should paint a thin layer of HT silicone on the nozzle to try to make PETG stick to it less. I tried to season a nozzle with oil, like one may season a skillet, but it wasn't very successful.

The results are pretty much as I expected from what I knew about nozzles. They have to be pretty messed up to dramatically affect print quality, though actually meeting advertised specs can vary, hole size is key, and the internal design will obviously affect flow. Length, mass, and material will all have an impact too. BTW at 10:30 your image says 0.2975, your subtitles say 0.2075 (lol), and you say 0.28, so which is it? XD

The nozzle with the groove that left a clean ridge on top of the the extruded line opens up an interesting opportunity for creating cross linking between layers that goes beyond the normal standard single planar surface. Having it shaped like a + or * would ensure ridges are created regardless of orientation of the line relative to the nozzle groove. It could act like chopped fibers do to create linkage between layers.

Perhaps try a three-point lighting setup? I’m no expert, but I’ve been deep into 3D printing for the past few months and have absorbed as much educational content as possible. In that process, I came across one of Zach Freedman’s videos where he discusses and demonstrates three-point lighting, and the results are impressive.

I suspect it has something to do with nozzle wear or damage, but I don't have the tools to investigate further. Would love to see how your different nozzle work on an overhang test. It would also be interesting to simulate nozzle wear with abrasive filaments. A few hours of GITD or CF filament should ream out a brass nozzle a good bit.

Hi What a super deep dive video. I'm looking forward to your upcoming Diamondback video. I own an original Revo Diamondback 0.6 and I'm not very happy with my decision to spend that much money. First is that the performance is only on the level of normal brass, despite of the talking of super thermal conductivity of diamond as material. Second my print results are somehow not looking very well. What astonishes me is that when I do free flow test ( f.x. to find optimal flow rate ) the outcoming string measures ca 1.2mm instead of expected ca 0.6. I have never seen such swelling on f.x. my Bontech nozzle. I wonder if there might be higher stress of the material because of inserted diamond shape. Do you see whether there is a very different "compressing" form that augments the material stress ? P.S. All in ASA with different temperatures tried.

I assume the bubbles from the wedge are because the printer is extruding the amount needed for a specific thickness. If you have a wedge, in ever direction but one (tip moving with the high end in front, low end in back), the printer will be laying down more filament than it's supposed to, so you will get thick areas and then every so often it won't have enough filament to cover the area which will leave a gap. It will also blob up a lot, as it will be almost like you have the tip too far from the build plate.

I always assumed they where so good that they didn't get worn out but maybe the wear simply doesn't matter.

I honestly bought a cheap pack of 20 brass nozzles (0.4mm) and... really haven't had issues. I mean I had other print issues, but I never thought "it was the nozzle" causing it. looking for wear, or probing with a 0.4mm needle or anything can quickly tell if it is time to change nozzles, and i've always kept old ones. The reasons why are .. I always figured I'd get equipment to drill them out to larger sizes to use. It may no longer be 0.4, but 0.56 or something, so drilling it out to 0.6 - makes a new 0.6 nozzle to use. And drill bits/drill aren't actually that expensive - even if you buy the better quality ones, for this 'light work' (brass isn't a particularly hard metal to work) - best part is.. you can even 3d print brackets, holder and a 'drill press' device to do it.. sure it's not 'as cheap' as just buying some 0.6mm nozzles, but... your also re-using (the second most important of the R's) the old brass... without having it sent out to be re-melted into something else.

Why actually? I don't get it. The flow comes from the extruder not the nozzle. If you have 0.6mm extrusion width specified, you will receive a material flow equivalent to 0.6mm whether your nozzle is 0.55 or 0.35mm in width. Then you have max volumetric flow which is safe for a given nozzle, temperature and extruder combo. You can't calibrate underextrusion out by flow% if you exceed that, because you always have print features which run at different speeds, and also you don't always print with the same layer height.

PLEASE DO CHT STYLE NOZZLES!!! DIY PERSPECTIVE has done some fantastic videos testing them and I would LOVE to see if the results are repeatable. especially with the coated brass nozzles and the hardened steel ones with copper inserts. especially with the comparison of cheap CHT clones and replacement hotends for bambu printers, as well as the new E3D High Flow ObXidian hotend for bambu as well. he also tested layer adhesion at higher flows which had some insane results! thank you for these videos, they are extremely enlightening. I am relatively new to 3d printing (followed them for ages, only bought one late last year when the p1s was 699) and there is so much to learn, even more when you consider how many innovations the space has gotten recently that isnt just "new printer cheaper and poopier!"

Thankyou for the videos. I do love the images you are producing. I was wondering if you could do a discussion about the other end of the nozzle as well. Leakage of the filament from poorly seated nozzles against metal or PTFE tubing is also a real issue. I am surprised they go for completely flat rear ends when a grooved circular cut (for metal) or having and internal shelf (for the plastic tube), would have sealed things better.

tbh - this hasn't been something I've seen since the ender 3 (OG) days. Most (all?) printers sold now use metal heat breaks so there's no PTFE. I mostly use brass which is sort of predisposed to compress against the fitting (why it's used for plumbing I guess). Not seen any leaks though at all, in the hundreds of nozzle changes I seem to find myself doing, so if you see one, I'd be interested to know what might have caused it.

If the printer used nozzle probing, a longer nozzle should be fine, other than cooling. CNC kitchen had a video on just using a volcano nozzle on a regular hotend. Shorter may work, look for clearance. Upgrade the whole hotend, I think microswiss makes a drop in replacement.

This episode reminded me of a Mosin Nagant I had that would consistently jam with steel cased ammunition. When diving into why this would be, I found that the cause was the chamber was narrower as the reamer that reamed it back in 1936 was likely worn down from use. I ended up having to abrade very small amounts of material and polish the chamber little by little to get it working flawlessly. Trying to drill or ream holes in metal, even precise holes, is never as exacting as we'd like it to be. Reamers and drill bits get worn down as they are used in a factory setting and the first hole you drill with a brand new bit will be larger by some degree than the very last one drilled before retiring that drill bit. I imagine in a factory producing thousands or millions of nozzles, this is something that will come up. A factory producing nozzles that is very interested in absolute precision will swap out drill bits much more frequently than one that is not (and there will likely be an added expense to compensate for that). On the other hand, what you've shown here is that variance may not matter as much as we think it might, to a degree obviously, but it's still fun to nerd out over it.

Any chance you can also test a TC nozzle? I've been using a 0.6 from spool3d for 2+ years, as I print glow in the dark tpu for business. It's doing as good as the day I got it (I think), but I always wondered if the orifice is the right shape/size, and if I'm better off with something less durable but from a reputable source like e3d. Awesome video btw. Thank you so much! And more sub jokes please :)

Increase your flowrate and don´t go crazy with the tolerances when calculation max. vol. flow. No wonder my prints are always great, I don´t care about the nozzle at all, it just provides an opening for the filament that´s it.

The Prusa vs generic I guessed correctly on all of because of the minor defects which appeared more prevalent on one print than the other (I assumed the better results came from the Prusa nozzle). The E3D vs 8 generics I failed spectacularly on, but I think that print is a bit too simple to really weed out the bad nozzles from the good. I’m not saying there’s huge differences, but there appears to be some nuanced benefit to using the genuine nozzles as the print gets more complex. Okay. Haven’t seen the rest of the video yet. Will update at the end

Dude! You have a very sharp British humor. I like it! So, maybe I missed it, but does a square orifice have any effect on corners? I notice that printing something like a cube creates roundish corners that bulge out just a little. It seems to me that a square nozzle hole could improve that. What do you think? Also, just wondering, but is "extrudate" a real word?

This is a topic in 3D printing that comes up constantly. My position on the subject, it depends. I believe cheap nozzles have their place, for me it's usually on cheap printers. If I'm printing something and I really don't care how it looks, as long it's dimensionally accurate then cheap nozzles are adequate. If I'm using a more expensive printer and print quality is important then I'll spend a bit more on my nozzles, generally around $15-$30, E3D, Micro Swiss, Slice Engineering. I've never really spent much more than that on a single nozzle but I'd consider a Obxidian from E3D.
