The Hardest 3D Printer Nozzles In The Universe: DiamondBack. 

lasers, of course!

Yeah, laser was my first thought on how to cut them. You don't even need that much power. Diamond isn't heat resistant like other forms of carbon, it will start to burn into graphite at 700C if it's not pressurized.

"Sharks with frickin' DiamondBack nozzles attached to their heads" (sorry 😅)

Considering these are synthetic diamonds I might also guess that they are formed in this shape which might also be why they are smooth but still slightly fuzzy.

the cover was also already cracked :)

best drunk purchase ever

@@LostInTech3D it treated me much better than the 5 pound gummy bear!

I put a .6 and a .4 on my printers and haven't given a thought to nozzle tips since!

awesome, is it not recommended to use this type of nozzle with a glass bed?

@@TouchofDepth i suppose just never ever jog it too close to the bed

@@TouchofDepthonly if you plan on crashing it into the bed. But also, who still uses glass beds? To each is own but thats just old tech. Get a good reputable brand smooth pei and put that glass in the dumpster lol

@@gsdtdeaux7 Glass bedsare cheap and you can replace them with dollar store supplies I guess

@@TouchofDepth I use it with my glass bed on my CR 10 V3 just have to be sure you set Z offset right and do not crash into the bed, any nozzle can break a glass bed this way

Glad to help, yeah those bambu ones are brand new, you'll be one of the first owners!

Thermal conductivity*

The whole diagramm is totally messed up.

My son was surprised the first time he saw my diamond tile blade. I explained that pretty diamonds are expensive when you buy them, cheap when you sell them. Other diamonds are common in cutting tools.

Yup plenty of people think any diamond is expensive. I've had many people shocked when I told them they could buy like 10 pounds of diamonds for less than 100$ But this diamond is synthetic and formed which is why it's so smooth and shows no cut lines.

cody's lab recovered diamonds from street dust where constructors are cutting

who has them for bambu printers??

​@@LostInTech3D E3D does, can also be seen on the diamondback website

@@LostInTech3D revo

@@LostInTech3D Believe it's only possible when using the BIQU Panda. It would be great if there were a fully assembled Diamondback Bambu hotend (high flow), like there is for E3D's ObXidian.

@@LostInTech3D E3D sells them, but they seem to all be out of stock.

Pros and cons, as always. Personally, not accidentally breaking the stupidly expensive part because I was a bit rough on it is worth those cons.

Was probably meant to be a thermal conductivity scale instead.

@@roderik1990 That would make sense

Thanks! :)

Is it more prone to clogging than other nozzles, or is it just it can clog like any other nozzle can?

@@arthurmoore9488 It's probably about the same. Maybe a little more frequent since a diamond nozzle isn't going to wear like a bronze one so you can trust the orifice to remain at the specified diameter when the bronze ones start tearing itself open from the heat and pressure. The problem is that this is the kind of nozzle that you don't just throw away, so the extended use time means that it WILL clog eventually.

not sure, could be the brass I guess.

If the diamond part is shrink-fit (which seems reasonable), it could become loose at high temperatures? It looks like the theemal expansuon coefficient of PCD is a lot lower than that of brass.

its the Brass around the tip that is the limiting factor.

Brass could be the limiting factor, however Tungsten or hardened steel insert variants do not have the same limitation imposed.

I have the phaetus tungsten carbide waiting to do something with :)

@@LostInTech3D the pheatus one is not completly tungsten and way worse

​@@LostInTech3D As other have said, the phaetus WC and SiC nozzles use press fit inserts, and those are not good for a multitude of reasons. The best thing is a full WC (tungsten carbide) nozzle, like the bozzle/oston/undertaker/nanoflow/panzarnozzle

@@LostInTech3D I heard on the voron discord that many people had problems with the pheatus one since it is not a whole tungsten nozzle, just a insert

​@@adeowungsten carbide

Not really, but explaining why is quite hard and I'd probably get it wrong. The tip always wears disproportionately too as it's from being dragged over the printed surface

Good idea

Indeed you’re right. I’ve had to bump up my flush volumes in both my Voron and Bambu since equipping them with a cht nozzle. Especially black to white.

The wear resistance seems to be the major selling point. Especially when working with engineering plastics which are highly abrasive. The higher conductivity is good, but only if you have a good heater and thermocouple right next to it. Along with good control software. The problem with large thermal mass is the control system might not detect a problem until it's too late. A relevant comparison is soldering irons. The cheaper ones have a heater cartridge, a separate thermocouple, and a changeable tip which slides on top. The more expensive ones have all three integrated. The "tips" are a solid piece with at least three conductors. V+, Gnd, and sense. They have less thermal mass, so heat up and cool down quickly, but the controller can maintain temperature better. That's important as soldering large parts wicks all the heat out of a regular iron, and it takes too long to catch up.

DiamondBack provided them 😁

I am, and I do 😂

@@LostInTech3D 😞I wish I could find one to buy, but searching is futile given the available terms. I have a 1"x3"x1/4" piece of pyrolytic graphite, ready to be split into knives, but I want actually use the diamond for heat distribution on an electronic component.

@@WaffleStaffel Just contact the company. It's probably not cheap, but they'll certainly sell it to you. Heck, I think this is the only product they sell directly to consumers. Which is a pity, because I want a 1/8in sandblasting nozzle made of the stuff.

@@arthurmoore9488 Good idea, it's worth a shot. I guess since a heat pipe has 3x-45X more thermal conductivity, diamond is better off as a novelty than a practical component cooling material.

Prusaslicer uses .45 for a .4 nozzle on most printer profiles, they kinda already are ahead of the game on this one 😁

Oh yeah, I'm 100% up for that. I might be the only customer though.

Not to mention you can reach high temps with TC. A PCD tip does nothing for you when you stick it in a brass nozzle. Have fun not going above 300C.

that's kind of how the flsun S1 is configured, and how it gets so high flow

I'd say yes

But would that actually work, and is it worth it vs just ordering one from a custom manufacturer? Seriously, I know Tennessee Abrasives does custom orders for not too much.

I suspect it's imminent

Well slice engineering just released the Mako

they have, revo diamond

not sure - Tom Sanladerer did some pretty exhausting testing on those.

Metallurgist here - polishing surfaces and then looking at them under high magnification absolutely is a thing to look at the crystalline structure at the micro scale. While there are certainly applications where inspecting samples in the as-polished state is useful (looking for inclusions in steel and evaluating graphite structures in cast iron are just two examples), it's usually more helpful to use a process called etching to better reveal the various grains (crystals) and the boundaries between them. This process got its name from the most common method of revealing the grain structure - applying acid to the sample, which preferentially dissolves some grains more quickly than others depending on their orientation to the surface. There are other methods that can be material- and sample-specific, including "optical etching" by way of polarized or oblique lighting techniques. I'd love to be able to comment specifically on diamond, but my best reference book for ceramography (something I haven't even accidentally done once since 2011) is at my desk at work while I'm off all week for our annual plant shutdown. It's not impossible that something in the grain structure could be revealed in the as-polished condition under polarized light, especially if impurities collect at the grain boundaries, but a tint etch, heat etch, chemical, or electrolytic etch may be necessary to really make it pop. And it's highly likely that higher magnifications would be needed - most macro imaging equipment tops out in the 50-80x magnification range, whereas my inverted microscope at work has objectives at 50x, 100x, 200x, 500x, and 1000x and some specialized models can go well past 2000x, into "poor man's electron microscope" territory. And now I'd love to see someone put a Diamondback nozzle into an electron microscope to see what can be seen at extremely high mag, and to run a spectral map via EDS to look for impurities and how they may be distributed.

@@justinchamberlin4195 SHHHHH with this talk hes going to need to buy more gear. Im am impressed at the quality of the shots he has in this vid tho. Maybe "Breaking Taps" could throw some electrons at it? IDK Yeah to see the structure is cool like a carbon opal type conglomerate but without a matrix? Maybe Im just mixing up stuff and this can be explained easily differently. like its just rough diamonds pressed to be a bigger one 😅. Either way that tech/process is really cool.

Yeah

tungsten filled petg prusa sells would be bad ish for tungsten nozzles

I only ask this because I really do appreciate your content, this should be a way bigger channel x

I think it's more about just being obsessively curious about things I'm interested in. No engineering qualifications unfortunately!

He's too modest to tell you, but it's 'just a smart mofo' option ;)

Skip the revo it’s really slow

Yes, I have the revo version and I'm disappointed by the mediocre flow rate.

@@michaeleitel7186 get the v6 nozzle you will have more options for hot ends and its the most supported thread size

I'm guessing that might be one of the things that sets them apart - I've not seen any first hand accounts of broken diamondback nozzles.

@@LostInTech3D I can't believe the "cheaper" guys get any sales at all, because they're not actually that much cheaper. $80 instead of $100, and you get shoddy workmanship or QC while still spending quite a lot for a nozzle

I've added a correction, it's the order of the labels that messed up

I made a video about it 😁

@@LostInTech3D cool! I wish there were more wacky, exotic filaments like that around

Nothing sticks to it but if you get a bigger blob started it will stick to the brass portion above the diamond tip

@@cameronheinricks8571 I've been debating getting one as I print lots of CF PETG for products I sell. PETG blobs have messed more than a few prints for me

there's a correction :)

Tungsten filled filament that is used for radiation shielding...

I figure it'll have to happen at some point but....at the moment I don't even have room in the studio unless I get right up in the camera and nobody needs that lol

you'd have to call that machine "Sisyphus"
