About this item

  • Extreme Durable: Hardness of 9 Mohs, the same as Ruby nozzle, it provides highest hardness and far superior to ordinary hardened steel nozzle, so it could ensure continuous printing without replacing nozzle, especially printing with filament such as Carbon Fiber, PEEK, etc
  • High Temperature Resistance: Temperature resistance up to 550 ℃, which is the same as copper plated nozzle, but Tungsten nozzle is more wear-resistant than copper plated nozzle
  • Good Heat Conduction: Thermal conductivity of 130W/m·k, much better than Rubby nozzle(45W/m·k) and hardened steel nozzle(26W/m·k), the better thermal conductivity greatly speeds up filament melting speed in hot zone
  • Low Expansion: Expansion coefficient of 4.5μm/m·℃, much lower than copper plated nozzle(16.7μm/m·℃), so it can adapt to continuous high temperature printing without deformation, especially when printing large-scale molds
  • Compatibility : These 3D printer nozzles compatible with MK8 hotend of Ender / CR series 3D printers. Also compatible with CR-10 all-metal hotend, Prusa i3, Anet A8, Reprap, etc


Product Description

Tungsten Carbide 3D Printer MK8 Extruder Nozzle, High Temperature Printing, Super Wear Resistant

Tungsten Steel MK8 Nozzle

  • Tungsten carbide material nozzle, It is suitable for long-term continuous 3D printing, avoiding precision reduction caused by nozzle wear.
  • Compared with other material nozzles, it has advantages of High Temperature Resistance, High Heat Conduction, Low Thermal Expansion, High Hardness.
  • The whole nozzle is cemented carbide formed by High-temperature sintering, the material is tungsten carbide (94%) and zinc (6%). The thermal conductivity of tungsten carbide is second only to nickel plated copper and superior to brass, which ensures the speed of nozzle heating. Which solves hardened steel nozzle shortcomings like poor thermal conductivity and long heating time.
  • The hardness is comparable to diamonds (9 Mohs), it solves the problem of poor durability of copper plated nozzle, especially for abrasive material filament such as carbon fiber, Peek, glass, wood.
  • Compared to other materials, it has the lowest expansion coefficient. So the nozzle hole has the smallest deformation during printing, which can achieve better wire output accuracy.
  • The highest working temperature (550℃) allows it to work on most high-temperature printing.
  • It is MK8 1.75/0.4mm nozzle, fits for most Ender and CR series printers whose extruders using mk8 nozzles like Ender-3, Ender-3 V2, CR-10, etc.
  • Dawnblade is committed to providing novel, practical and high-quality 3D printer accessories, most of which are matched with Ender and CR series.

I bought this to print abrasive media, but it is hardened steel at best, and a scam at worst. I'm going to try it out, and I know tungsten can be mildly magnetic based on processing, however the strength of the magnetism is the same as my hardened steel nozzles, we shall see.

This is a great replacement nozzle for anyone looking to skip replacing cheap nozzles or needing the hardness for abrasive materials. However, we don't know what grade of tungsten carbide this is. Nonetheless, it's safe to say this should be lasting years and years with the intended use. Also claims better thermal conductivity than brass but this shouldn't be the case. Tungsten carbide seems to be around 85 W/m.K, still better than steel or ruby. Would Recommend.

Tested this nozzle before printing something big. Printed a benchy and the benchy that was printed was better than the nickle copper plated nozzle that came with the spider 3 hotend. Brass on the other hand, it looks very similar. I just printed something for over 14 hours and so far it prints really well compared to hardened steel.Only time will tell but so far so good, I only bought this nozzle because I just want to set it and forget it. I don't like changing nozzles. Call me lazy but got tired of changing nozzles from brass to hardened

I have used cheap Brass and hardened steel nozzles in the past to varying degree of success. I have NEVER gotten any hardened steel nozzle to lay down CF-PETG as smoothly and constantly as this nozzle. I have only had it for a few hours on the printer but switching from a quality steel nozzle to this Tungsten Carbide one (after doing a PID Tune) This is the most consistent nozzle I have used to date. The $24 for one nozzle is kinda a killer but this is a nozzle that will stay for likely the life of the printer, even if it gets clogged its worth while to unclog it with a torch and needle.Iv used PLA, PVB, and CF-PETG on this with great results in the little time iv had with it already. |Highly recommend, If anything changes expect an update, otherwise assume everything went perfect.

So far it's going well. I have not yet done any harsh firaments, but for PLA, it matches brass for temperatures. I got a project using wood filament and I'll see how it handles that, but for now, I like it. I just wish it came in a 0.6 so it has less risk of clogging.

This is a great lifetime nozzle. I originally ordered my first one about a year ago. Installed on my Creality Ender 3 Pro. I screwed up the installation and severely clogged the nozzle along with lots of burned on filament. With the help of a heat oven, heat gun, nozzle pin, nylon filament and steel brush, I was able to make it good as new. Nothing can scratch it, so I took the chance, and it paid off. I have since upgraded to a Sprite extruder and installed this nozzle. The Sprite has a differently shaped nozzle, but the threads are compatible, and the silicon sock fits the MK 8 nozzle just fine. I have been printing for about 7 months with this nozzle using wood, glow in the dark, PLA, PETG and TPU filaments. It will not quit. Each time I purge filament, the nozzle pattern on the bed is a beautifully symmetrical circle. The filament comes out evenly every time and nothing I've tried can dull it yet. It has not clogged since the initial incident (my fault). Thermal conductivity is better than brass in my opinion and it does far better than steel because I don't have to dial up the heat block temperature to get results. It also seems to purge easily when I change filament without having to do cold pulls.There is one warning I must give. I have ordered two more of these because I am buying a dual extruder printer. I received one which was the actual product. The next one arrived and contained a used and blocked brass nozzle. I do not think Dawnblade did this on purpose. I believe someone returned the brass nozzle to get a refund and kept the tungsten one. Dawnblade didn't check that they had been ripped off and sent the returned item to me as new. I have returned it and have another on the way. I hope Dawnblade catches the thief.These are hard to get items. It can take some time to get stock in. Make sure the nozzle looks like the picture when you receive it and make sure the weight is heavy. That is the proof of a Tungsten Carbide nozzle. Test it right away to make sure it is the real thing. Nozzle temps should be similar to brass and they should hold up without wear with almost all filaments, including carbon added ones.Well worth the investment for a nozzle that will last. Just do an inspection as soon as you receive it.

This nozzle is awesome. I have been printing PLA exclusively for several years. I recently found myself needing to print a more durable and thermal resistant filament. I decided on a popular CF PC. I do have a all metal bimetallic hot end with brass nozzle. That carbon fiber tore up the brass nozzle within a dozen layers. I had already ordered this nozzle and thankfully it arrived the next day. Only took a few minutes to install it in my Ender style hot end and I was back in business. After the usual new nozzle calibration I tried again. What a difference! Part finished flawlessly. Very nice perimeters and layer adhesion. This is the product to use to print that nozzle eating polycarbonate or carbon fiber filament.
