M6 High Temperature High Flow Hardened Steel Nozzle 0.4mm Compatible with 1.75mm 3D Printer Volcano Hotend Heat Block Sidewinder X1 X2 AC Vyper Kobra Max Print PEI PEEK Carbon Fiber (0.4mm)

I bought this nozzle and a brand S nozzle in .6 width to use for printing TPU. I suppose because it was nice and shiny, I ended up using the brand S nozzle. My TPU prints had a distinct graininess to them, but I figured that was normal. Well, one day the brand S nozzle clogged and I switched over to this nozzle. Wow, what a difference in print quality. I don't know if the steel holds the heat in better or what, but my TPU prints are smoother and shinier. A most definite improvement. This will be my go-to nozzle for TPU going forward. If you level your bed when you swap out nozzles, you won't have any z-height issues or gouging of the bed.

If your review mentions the nozzle is too long, it's time to return to 3d printing school. Those with nozzle based auto leveling will simply need to run the auto level. If you have a manual bed, you manually adjust. If you have a bltouch or other leveling sensor, Google how to modify its height. Never clogs, hasn't worn, still working well. I'd say it's a good product in general.

I was trying to print PETG and kept getting issues with it not adhering and stringing. I'd printed the same exact model out of PETG previously with no issue. I thought perhaps I'd tinkered with something in my slicer that was causing it. So, I tinkered with the slicer settings and tried multiple prints, multiple times and just could not get it dialed in. Then a light bulb went off...I'd forgotten I changed the nozzle to this one. I put my old nozzle back in and printed the first time flawlessly. Stay away from this one, you will get print quality issues.

It ultimately didn't work in my machine, and I'm not entirely sure why? But the nozzle itself seems great! Solid build quality for sure

Ok, so some have complained that the tip on this is different/longer then the normal nozzle, and to that I have to say "so what?" it is no big deal, just level your bed properly as you should each time you change the nozzle and you will find that this nozzle works great, matter of fact I almost like it better then the coated stainless I use. This nozzle prints like a dream with all sorts of materials, but I primarily use it for wood and carbon fiber materials and it works great for that. So don't let the other reviews scare you about odd length on the tip, if you know how to properly level your bed (build surface) then you won't have any issues!

Have not yet installed this hardened steel nozzle, but noticed that its cone is significantly longer than every other volcano nozzle I have. The thread length is the same, as are the flats on the end nut, but the cone angle is steeper resulting in the extra length - measuring just by eye, it is somewhere between 2 mm and 3 mm longer than a regular volcano nozzle cone. The impact of this, since the rest of the hot end will remain unchanged, is that the nozzle tip will wind up 2 to 3 mm closer to the print bed, and the print bed will need to be lowered by that much whenever this nozzle is installed (and the inverse when changing back to a regular nozzle). This is at best inconvenient, for those like me who use manual bed leveling, and at worst a potential disaster, if inattention allows damage due to bed contact. Maybe I am ignoring something potentially useful with this cone difference that makes any extra changeover effort worth it - maybe there is less chance of filament curling back and sticking to parts of the nozzle with a steeper cone? Perhaps this nozzle will print both abrasive and regular filaments equally well so that the need for nozzle changes is reduced or nearly eliminated? I don't know, but until I get the time to find out, two stars off for being physically different from normal cones with no explanation or installation warning.

The flatter nozzles get all gunked up with extra plastic and make a mess randomly. This one seems to self clean and brushes anything off easily. Less maintenance, less worry, excellent prints. Totally worth the 11$. Nuff said.

This hardened steel nozzle shows no sign of wear after more than eight kilos of carbon fiber nylon and three kilos of glass fiber nylon. No complaints at all.

El último filete de la rosca no está bien hecho, además de ser diferente al de la foto(acaba recto y no de forma tronco-cónica dificultando así el montaje. La forma no es hexagonal,necesitando una llave fija para montarla, lo que dificulta algo el montaje(es más cómodo usar una llave de vaso pero ésta boquilla no lo permite) El orificio de salida parece bien perforado, centrado y con el diámetro correcto Una vez montada , de momento no he tenido problemas. El material parece bueno y resistente Espero que las fotos puedan servir

Install and forget - you're not going to wear these down anytime soon! Got these on my Sidewinder X1 which runs a volcano to 100mm/s and had no issues at all with these. With them being hardened steel rather than brass, remember to re-PID tune the hot end and maybe bump your print temp up 5C to account for the difference in the thermal transmission.

The tip of the nozzle sits lower than the stock volcano nozzle, so it's frustrating swapping between nozzles. It prints really well though, so if you're only going to use this nozzle you'll be fine after making your initial adjustments. But I don't think I'll be using it again because it means re-levelling, changing z-offset, and using an adapter for the fan to make the fan's airflow go lower and onto the print, rather than blast the nozzle. None of my other nozzles hang that much lower, and they all sit very close to the same height as the original volcano nozzles.

Tête de bonne qualité mais je trouve chère pour ce que c’est. La tête a réalisé de très bonne impression depuis son installation.

Au bout d'une quinzaine d'impressions la point de la buse s'est émoussée de 0,3 mm . J'ai du effectué un nouvel Z offset avec mon BlTouch de 0,3 mm . Si cette buse était en acier trempée elle n'aurait pas perdu 0,3 mm . Très déçu de mon achat , je me suis fait tromper sur la description de cette buse . Passer votre chemin.
