Ruby Volcano Nozzle Abrasion Wear Resistant High Flow 0.4 Sidewinder 1.75mm Hardened （Volcano, 0.4mm）

I really wanted to get into printing some glow-in-the-dark filament; and had seen horror stories of certain filaments just tearing through brass nozzles. There is certainly an argument to be made that brass nozzles are cheap and for the price of one of these 'exotic' nozzles, you could buy a dozen brass ones, but I don't want to deal with that. Waiting for print quality to deteriorate, then having to partially disassemble my extruder to get a wrench around the hotend (dumb design)... I tried hardened steel to really awful results. Even printing 20º over brass nozzle temps still somehow resulted in poor layer adhesion, poor bed adhesion - and all sorts of weird print quality issues. Most of these went away if I slowed down the print, but that's not worth it IMO. I really wanted to try a diamond nozzle after watching @ZachFreedman's review and factory tour on Youtube, but $100 is still real steep. Somehow only then I became aware of these Ruby nozzles and they seemed like the perfect combo of good thermals, durability, and price - so I took a shot. Long story short, I'm never going back. Print quality is amazing. I haven't compared the same print side-by-side, but I swear this nozzle prints silk/glossy filament better and leaves a shinier surface finish than brass. I've only run about 500g of glow filament through it so far, but so far, no nozzle wear. Still prints bang-on dimensions from when I calibrated my extruder just after swapping it in. I did wear a chunk out of a plastic trim bit at the top of my gantry where the glow filament was sliding over though! If you're here because you're not satisfied with your hardened steel nozzle - this is the fix. Is it an upgrade over brass if you're not concerned about wear? That's debatable. Also I've heard Titanium nozzles transfer heat better, too - but I haven't given them a shot. I don't have any reason to now!

I picked up the 0.6mm nozzle and have tried it on a few prints. Other than the different profile of the tip end, the physical nozzle does appear to be the same overall dimensions as my existing E3DV6 nozzle. I tried the 0.6mm on a PLA print I had done previously with a plain brass nozzle. I used the same gcode file and the print came out excellent, without any issues or poor quality. I then used it for an ASA print. I realize you can print ASA with a plain brass nozzle but I wanted to compare results with this nozzle. That print also print came out with very good quality and no issues. I like how these nozzles seem to be able to use the same settings as a plain brass at the same size and should last much longer due to the ruby tip. I will be trying some abrasive materials soon, so I went ahead and ordered 0.4mm and 0.8mm Ruby nozzles based on the performance I have seen so far. Being able to print abrasive filaments without the issues/stringing usually associated with hardened steel nozzles will be a big plus. Value for money: time will tell if these are with the extra cost. If they manage to last nearly as long as hardened steel, then I think they very much will be.

It worked amazingly well during the first month and a half, 2 months. I was printing amazing quality stuff and then it started getting clogged, then under extrusion started to become a big issue even though it's the same gcode/files. Tried clearing it up, cleaning it and it worked well for 2 days... then back to giving me issues. maybe it's just me? EDIT: Just wanted to update and say that the company reached out to me, gave me feedback and suggestions and was very helpful overall. Unfortunately my printer didn't make it long enough for me to properly try out the solutions. Overall, this ruby tip nozzle is amazing compared to the common ones. I will give it 5 stars because of the amazing quality it did provide.

I bought this after so much reading and research I thought it was impossible to go wrong but here we are. I bought it for our printer I run the most aggressive filament on, tpu, silks and clear filaments to help with clogs. The machine was running great when the new nozzle arrived but I really wanted to try it so we put it on to give it a go... and no go. IT WONT FEED FILAMENT. The nozzle is so small I can't get my cleaning needle in without it scraping and a ton of resistance and I can't get through even one line of brim on any print before it completely clogs and won't feed at all. Changed the nozzle back to the one that was on it when this one arrived and had no problems so I know absolutely its the nozzle. I'm so disappointed as this was supposed to be an upgrade and for the expensive price its very sad to literally never get to use it. I would never recommend this to anyone unless you want heartbreak and a broken printer.

Update: The seller contacted me after my review and offered a refund or replacement even though it was outside the return window. I have to say the customer service was fantastic and I believe the nozzle I had may have been a one-off issue. I'll update this review if the replacement nozzle which is what I opted for works well. I had a print that I just couldn't get to come out right. After trying different settings, I finally checked the nozzle. There was a chip to one side causing the PLA to extrude to one side. Maybe this onw was a fluke but they're too expensive to take the chance that it will chip again. I may give the tungsten or diamond nozzles instead.

I saw a comment on reddit that remarked a ruby tip nozzle handled silk filaments much better than traditional brass. Ruby tipped nozzles are kinda pricey so I was hesitant but this one was an affordable option and I am glad I tried it! I didn't need to change my profile at all and I have had good results printing with it so far. Usually matte filaments give me the hardest time, silk is a close second, but I printed a whole spool of matte without any problems and I've done several spools of silk. Not to mention zero issues with my usual PLA. We'll see in time if durability checks out, but so far I am not getting any signs of wear.

so first off,i bought a .6,but setting my slicer to .6 made gaps between layers,setting it to .7 fixed it. when using a steel nozzle,i was printing cf pla at 240c,230 and it wouldnt print,any higher than 240 and it would start to smell burnt,this nozzle let me print atan extremely low 170c,which is ridiculously low, with normal pla,which wouldnt extrude under 200 on a brass nozzle,it wouldnt extrude under 220 with the steel nozzle, the nozzle's print performance is very good,but thats not hard to accomplish,thats a requirement,not an expectation.

Bought this to print with carbon fiber PETG on AnkerMake M5C, the print went well. One gripe is that you need a 7mm socket rather than the 6mm the official nozzle uses, so you can't use the wrench the printer came with.

Highly recomended seller.

Ruby insert broke after clogging. Expensive rubbish.

Having had perfect prints with a hardened nozzle which sadly came to the end of its life i thought id invest in a ruby tipped 0.6 nozzle...BIG mistake, the quality is awful, despite the settings being for a 0.6 for some reason it isnt even able to join the layers together side by side, the nozzle says 0.6, the prints set for 0.6 the nozzle thinks its 0.4, my prints have gone from amazing to unusable. Needless to say its come out of the machine and bog standard nozzles that actually work have been ordered at a fraction of the price. This may be good for some filaments but wood pla no chance, dont waste your money.
