What Is A Bozzle Nozzle?

[@natalyakeane]

this is literally the perfect balance between the diamond/ruby nozzles and cht nozzles. feels like the perfect tool for carbon petg. would love to get my hands on one at some point, as id love to switch over to a material with the balance of printability and strength/rigidity/heat deflection specs like that as my daily driver material.

[@ModBotArmy]

I have been running the Diamondback nozzles for a bit and have been quite happy with them. However, I still much prefer a full TC nozzle as I feel the life expectancy will be much longer with one continuous alloy versus an insert. Also the added flow is a definite plus.

[@alejandroperez5368]

Why would you print in carbon fiber filled PETG? It's not even stronger...

I have been running a Dyze design tungsten nozzle for years on all my machines. I love them so much and have never had a clog.

[@JonS]

Thank you for covering this. Not many people seem to know about this nozzle. I bought one a couple of months ago because I was concerned there was going to be a patent fight that could see it disappear. Good to know their splitter hole pattern isn’t covered by the 3DSolex patent. I haven’t put it on yet. I’m still using a CHT on a Dragonfly BMO and haven’t needed to print any abrasive materials on that printer so far. Your video gives me new impetus to put it on and start playing.

[@ModBotArmy]

I have been interested in this nozzle for some time. I had originally seen Vez make a high level overview of the nozzle but aside from that I did not see much info out there other than in Discord. Glad I was able to shine some light on it. Due to its price it definitely isnt the nozzle for everyone but for those wanting a high quality nozzle for pushing abrasives with increased flow it is a solid option. When you end up installing it let me know your thoughts after some time.

[@truantray]

The funny part is that knockoff bozzles seem to work better.

[@SpartanLeroy]

@okleydokley I don't think there are bozzle knockoffs out there man. If they do exist I need proof it's a clone of the bozzle and not a cht

Love my bozzle nozzle! Have blow torched the thing a couple of times to clear out gunk. And the WC has withstood several kg of PCCF without showing any signs of wear, while still outputting at crazy flow rates!

[@ZombieHedgehogMakes]

I've been using West3D's Undertaker nozzles for the last few months and it's a great balance between never needing to change out your nozzle again, no temp drop like hardened steel, and about the same flow as brass.

[@stonecraft745]

A few years ago I machined a pair for myself, thought about producing these, but the price in comparison to hardend steel nozzles would have been like the factor of 8. So I ditched it, glad I can buy some now, if one of my nozzles ever wears out.

[@NickNick2024]

At higher flow rates, you can definitely run into limitations based upon the extruder. Hotend isn't always the bottleneck. Thank you for sharing info on this nozzle. I've been looking at the Undertaker nozzle (from West3D) for a while. It is solid tungsten carbide, without the cht type feature, for ~$50.

[@Tedlasman]

Hotend is a bottleneck. Higher flow hotend will allow for the extruder to work less. Everything works together

[@Tedlasman]

@@wyattutz I agree. gotta have a good extruder.

[@MrRocksalt]

This test seems relative. Put .5 nozzle on X machine, compare to bozzle. That's it.... if you need to use a different extruder that means that the nozzle has more back pressure than the standard .5 nozzle.

[@AmixLiark]

I really like the sharp, abrupt tip on this one. I bet it prints PETG much better than most nozzles because there's not a whole lot of surface area for the petg to stick too and slide up the side of the nozzle. I use a diamondback and i don't think it's great for petg for this very reason.

[@AndrewAHayes]

I have had 0.6 Prima Creator hardened steel nozzles on 3 of my printers for over two years for 16 hrs per day 5 days per week printing Nylon CF and PETG CF and they are still going strong, I get excellent quality prints from them so see no need to change as I cant see a reason to!

[@petercallison5765]

[@roTechnic]

Fantastic video, thank you! Any idea how the flow compares to the CHT nozzles?

[@ModBotArmy]

I don’t have first hand experience with the CHT but based on their claims of “at least an increase of 30%” and CNC kitchens tests I would say they have higher output. The trade off will be abrasion resistant. I did see they released a bi metal version but it doesn’t look as structurally solid as the bozzle due to it not being made from one alloy.

[@daliasprints9798]

For me, bozzle flow is somewhere between 0.4 CHT flow and 15% above that, almost enough to go same spatial speed even with the wider extrusions, but not quite. You can see it in action in some of my videos.

[@WhiteWulfe]

The bozzle is definitely tempting, that's for sure.

[@karellen00]

I have one and I'm really happy with it! Also no one mentions, but despite the complex geometry it's way easier than other nozzles to do cold pulls. Also with this nozzle I have been able to reduce quite a bit pressure advance and smooth time!

[@ModBotArmy]

I had someone ask about cold pulls so this is great to hear :)

Even at very high temps I cant print it as fast as say inland pla+ which can print at least as fast as my printer is capable of printing.

[@oxtx9885]

You forgot the biggest advantage over steel: The higher lubricity. Much lower chance of clogs with fiber filaments. Really cool, although unless I need to print over 300C I would probably go with the diamondback. But it is good to support small companies.

[@lennynnnnnn]

I think one of the best benefits is layer adhesion with this nozzle. Any better luck printing materials that crack (abs)? I also wonder if there is less curling / warping since the center of the extruded material should more uniform when compared to the ends. What are your experiences?

Daniel... you re-ran you tests on the Ender 5 Pro with the Microswiss NG extruder based on the manufacturer's recommendation related to tensioning. However you also changed another variable... the filament. Since changing two variables at once doesn't let you determine with certainty that the tensioning was the only impact on the first test, did you ever end up testing on the Ender 5 Pro with the original filament?

[@ModBotArmy]

I did not. Although I was quite confident that the filament was not the issue I wanted to essentially start with a clean slate when I switched printers. I did use the .5 brass vs .5 bozzle with the new filament on the NG to make sure they had the same test environment but I did not go back tot he original filament. Based on what I saw on the CW1 I do feel it was the extruder and not the filament but this is something to keep in mind for future testing. Thank you for the feedback.

[@AnIdiotwithaSubaru]

Do you know how the Bozzle nozzle performs with Petg? I print with mostly e3d NozzleX hardened steel nozzles and though they do a great job, the Pet loves to stick to the steel. I wonder how Pet would work with Tungsten Carbide?

Great to see your experience with the bozzle! Have you had any trouble with the nozzle coming loose in your hotend? After 1 or maybe 2 small prints, the bozzle has been coming loose in my v6 and leaking. I just ordered a rapido to see if that works any better. :/

If the block is aluminum replace it with a copper plated one. I could never get it to tighten properly with the aluminum block and ended up stripping the threads since it's so soft. The copper block I've never had an issue with and it's tightened up perfectly.

Very thorough to repeat the flow tests. It seems this nozzle geometry offers greater surface area to quickly melt the filament core at high flow rates, reducing resistance at the nozzle tip. However, this geometry is more restrictive at the throat, especially at low nozzle temperatures.

[@twanheijkoop6753]

It's the same with the clone cht nozzles. Since both dont feature any knife like edges at the start of the split/geometry change they work better in longer hotends where the material is already soft before it reaches that point.

Very nice vid! I have been waiting for a hardened version of the CHT nozzle so that you can get high flow and also print abrasives. This looks like a great option! A bit pricey at $75 US, so I will probably wait for a high quality clone. Also, on the tensioner.. I have had similar issues before on stock Voron extruders. I really like the LGX lite for that reason, because there is just a simple lever- it's either tensioned or not, there is no in between.
