As nice as they are, I prefer a solid carbide nozzle for one reason- the body of the diamondback is brass, and that part can still wear over time.

i have one of these on my K2 Max and i love it, it prints fantastic and allows me to print CF HTPLA for automotive parts. i have noticed the quality and consistency of my prints is very good as well. well worth the $100 IMO

I have one of these I purchased inebriated about 3 years ago. 4,000 some odd hours later, across 3 machines. Printing every filament. Zero issues. None. It’s a fantastic piece of kit.

I’m no expert but I don’t think the graph at 2:16 makes sense. Copper and brass are harder than tungsten? I use tungsten tools to cut copper and brass at my job all day.

Watched at 2x speed and there's still so much nonsense and fluff. Just get to the point.

I love my diamondback nozzle. Can you do a macro shot from threaded side of the nozzle to see what the diamond looks like?

There's a different brand on Amazon that sells what it claims to be diamond nozzles. If it's actually polycrystal diamond as claimed, it doesn't seem to be manufactured to the same high standard because most of the negative reviews I've seen of it is about how for some people the diamond tip has fallen out of the brass. I wonder if you can abuse genuine Diamondback nozzles until that happens to them as well

I have many of the Diamondback nozzles, and they are absolutely the best nozzles. They are worth it!

The fuzzy inside and outside is because they're cut with a laser. Carbon might have a high boiling point sure but dump 100KW of laser power in a single point and you'll make anything disintegrate. You can use diamond lapping compound to smooth it out if you want, but it's a lot of process time (and consumes a lot of diamond in and of itself (fun fact, the industrial diamond factory I did work for a while back was their own largest customer. 60% of the diamonds they produced went right into lapping compound and grinding wheels so they could cut their own diamond parts)).

Been wanting a Diamondback Revo nozzle, I know the tip won't wear but I'm afraid I might bend it by accident and I'll have to buy another one... lol

Hahahhaaa, love this video and its many many side comments. So just to be clear, the 1mm nozzle has superhigh flow, compared to other nozzles? How much higher?

I bet in the future Chinese shops will sell nozzles like this for less with the same or better quality. 🤔

You can get in every shop in the uk bananas without any problem in many kilograms if you wanted.

How can they make almost 69000 bar and keep the prossure under control for artificial diamond making 🤔

I'm interested in tungsten carbide nozzles and their lifetime. And other thermal conduct properties. I have 3 different sizes of Phaetus' nozzles made out of TC and for now, I haven't changed the nozzle. Only hotend. It's been great but I recommend filming those with macrolenses. Rough surfaces but job well done.

I have been using a diamondback in my v400 for a year now. It's amazing.

I'm dying to get my hands on one of those diamond discs! I'll buy it from you once you get bored with it. Unless you're like me, and you tend to accumulate toys and never let them go.

Is glass filled TPU actually a thing :o

Hardened steel nozzles seem to last me forever, I have had them on my Ender 5 Plus machines for over 3 years and haven't worn yet. It would cost me a small fortune to get a full set of Diamond back nozzles and just for one printer!

There are actually materials harder than diamond, though they are not usually naturally occurring. Lonsdaelite is one and can be found along with diamonds in some meteorites. Others are carbon buckyballs or nanorods, and graphene. But these last, while harder, can only be synthesized artificially, and as far as I know don't create solid compact structures.

Wow impressive flow rate- it just occurred to me that if you get the nozzle size close to the filament diameter you really don’t really need the filament to melt all through way through… hmmm

This thing looks amazing... but calling it a nozzle that "lasts forever" (as many people do) is a bit of a false point. the tip will last forever, sure... but the interior MUCH softer brass will get worn away over time, especially when printing CF. it'll last longer than regular brass nozzles... that's about it. you will have AMAZING prints... and then suddenly a catastrophic failure as the tip literally just falls out, or the wall behind the diamond tip just... blasts through as it gets worn thinner and thinner... like those ruby and sapphire tip nozzles. the brass behind the gem tips just get... worn away... Oh, and also, a lot higher risk when doing cold-pulls. I... really don't think they are all that worth it. Because of the brass "body" I physically cannot see them lasting as long as people advertise them to last. atleast when printing abrasives.

Polycrystalline just means that it is not all one single crystal, but a whole bunch of smaller crystals that grew into each other.

You should change your name to lost in nozzles at this point

I have a tungsten Carbide nozzle from Dawnblade on my V2 neo and have 0 issue with it and love it, have printed many abrasive things like CFPETG and glow in the dark pla. 0 issues. Only complaint is that there isnt a V6 version so i can use on my other printer.

2:16 - Wait, copper is harder than steel and tungsten carbide?? :O

I want your pitcher plants at 8:40! haha

till you get a clog and soften the blass by torching it trying to get the clog out and ruin the nozzle, tungsten carbide nozzle all the way

Unfortunately this definitely not a "forever nozzle" the brass will be damaged over time. By filled filaments, nozzle cleaning etc. A full tungsten nozzle will last way longer and may be the real "forever nozzle". If you really want a diamond nozzle, I would recommend the Trianglelab DLC copper one. At least more wear resistent than bradd.

"soft diamonder" LOL.

ok ok take my money!!

I guess I still would by Ender 3, instead of one nozzle tip = ))

sadly all multipart nozzles are flawed, they will eventually break apart. or they leak from the seal. full body tungsten carbide (oston, bozzle, deez) is significantly cheaper and while on paper isnt as good as diamond, id go with them anytime. remember theres no real benefit to use harder nozzles unless you are actually printing with abrasives. theres also the Gammamaster that ive seen quite a few people recommend but ive not used it, and the warranty excludes glow in the dark filamen.t the CHT is still the best if you aint using abrasives

As an employee and 3d printer hobbyist they made these for our own 3d designs for cases and custom organization on the production floor of drill bits being made, tool holders etc, when hobby 3d Printing took off that's when they came up with the idea to ramp up production of the nozzles and sell them. I have been printing with the same nozzle for 2.5 years now and its still clean and perfect, thermal properties are much better too that helps with layer adhesion among other things. The heated presses used for this manufacturing process are mind boggling and incredibly dangerous.

How much of the nozzle are Polycrystalline Diamond? It just says diamod tip the site. The inside walls of the nozzle would still wear and probably most of the thermal transfer are down with the copper parts?

I think your hardness scale at 2:19 seems off, Copper is harder than ruby????

You need to test it with PETG and especially with ironing top layer

I think your hardness chart was mixed up with the conductivity chart

just curious if you plan on testing the obxidian nozzles since they are a bit more affordable for the average user.

Great videos as always!

Interesting 🤔 would be good for very abrasive filaments

A HUNDRED QUID FOR A NOZZLE????

I watched the outro so I won't leave an angry comment about you destroying a perfectly fine phone screen

@2:18 the graph is incorrect - hardness of copper is second only to diamond?? Carbide, ruby, steel should be harder than copper as well

The graph you show at 2:14 is not the correct one. I think it might be the graph for heat conductivity, but definitely not hardness

I have a tungsten nozzle for my m5c in use now as well as a diamond 0.4 haven't used it yet $94.00usd is crazy but no need to change unless I'm changing diameter

Extrusion honing is a thing.. which is what’s happening.

Where's my diamond filament?

Great video as usual

"Diamonds! These are real! You probably don't believe me-" Huh? Is there still really people out there who think diamonds are expensive or uncommon? lol
