Tungsten Carbide 3D Printer MK8 Extruder Nozzle, High Temperature Printing, Super Wear Resistant, 0.4mm/1.75mm

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.

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

This is a size larger than most E3D V6 type hot ends use. SO the price is great, but beware the length is significantly different. You will gouge your bed if you don't account for the z-change and that may have to happen in the Flash, so better to just get the right size to begin with.

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.

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.

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.

Full Tungsten Carbide unlike competitors ( TC Tip only ) - Almost as hard as Diamond tip at a fraction of the price. I'm expanding to more exotic filaments like wood, glow, and metal infused, and I wanted to future my printer. I would highly recommend this nozzle over any hardened steel or ruby. Conducts heat just as well as brass too.I also went ahead and got me a copper heat block and a bimetallic heatbreak.

Tried installing this in my printer, took 2 days trying to calibrate it to work and no luck. First thing to do installing new hotend parts is PID autotune & calibrate e-steps. No problems there. Printing PLA behaved exactly like a $0.50 hardened steel nozzle, not a $40+ tungsten carbide nozzle. Flow was poor at best. The wide nozzle tip dragged across the material on the first layers and seemed like it was too high by layer 5. Consistent symptoms of underextrusion as well. Increase in temperature by 20-25 degrees and increased flow by about 15% seemed to make it work, but I bought Tungsten so I could use the same settings as brass. I don't want to waste time slicing everything twice for two different material nozzles.
