Your cart is empty.The tip of the nozzles are made with polycrystalline diamond PCD, an ideal material for 3D printing due to its extreme hardness and superior thermal conductivity. Its superior abrasion resistant property makes it suitable for highly abrasive materials eg. CF, GF, Metal filled etc. Work as an drop-in replacement of regular brass nozzle. It also works well with regular materials eg PLA, ABS, TPU, PETG etc.

I received the 0.4 mm diamond nozzle for my MK4S. I tested it, and so far it is great, but one thing needs to be improved to address my issue. The top, where the filament is going to in the top hole, needs to have a chamfer. I compared the stock nozzle from Pursa, and they do that for "smooth feed.". The issue that I have is the filament sometimes won't move as stuck because there's no chamfer.

It's been great so far. Good value. I would plan on chamfering the inlet side like the original Prusa nozzle if you buy it, otherwise the filament can catch sometimes being fed in. Easy to do with a regular chamfer, or a diamond cone shaped chamfer would work ok too as the metal is hard, but not too hard for decent hardened chamfering bits. I probably won't ever have to order another once, which is the point of the diamond tip, but if I needed another I would confidently buy more. I also purchased the 0.8.

It only was 14 hour of use with NYLON and PETG. I also started having issues as well. It had extrusion problems and bad inconsistent it was lousy. My brass nozzle would have printed a lot better then this nozzle.Mine started to leak too, take a look at the pictures! It was the Tungsten Carbide Nozzle 0.4mm.Mind wasn't free either!Don't believe those reviews. So be warned by buying this nozzle!UPDATE!Just wanted to give you and update. It's not a good one unfortunately it has the same problem take a look at the pictures! This is only 17hrs I printed with Nylon, wood filament and petg only and it started to happen again. So at this point there is a problem with the nozzle that's for sure, if I let it go on it well get worse and maybe ruin the hotend and loss 2x as much. The filament I using is eSun ePA12-CF , Wood , SunLu Petg.

Works well, no issues yet. Only time will tell if there's any faults or long-term issues, but so far, so good. Comes in a very stylish package, to boot.

This is a great nozzle, its well-built and solid for what it is. It fits my Prusa XL perfectly and works great. I don't have anything negative to say about it. I've ran several spools of carbon fiber filament through it with no problems. I inspected the tip and there was minimal wear, if any. It does take some tuning since tungsten carbide is kind of a pain to heat but once heated to the right temps, it worked flawlessly. I'd recommend picking up at least one of these if you plan on printing any abrasive filaments.

I have a Prusa MK4 and while I haven't used any particularly abrasive filaments, I always want to be prepared if I ever want to. When I saw this ruby replacement nozzle for the MK4, I ordered it immediately. Here are my thoughts.- Well packaged. The DUROZZLE ruby nozzle comes packaged in a nice plastic sliding case, cushioned by some soft foam. This part arrived in perfect condition.- Easy to install, mostly. I had never swapped out my default nozzle from when I first built my MK4, so this was new for me. I went ahead and first printed the MK4 nozzle replacement tool to allow me to more easily swap the nozzle without removing the whole hot end. (This is definitely the way to go, and I strongly recommend doing it this way.) I did have an initial issue with the filament not loading correctly. The extruder gear was clicking during loading...like it was not able to push the filament through the nozzle. I removed the nozzle, and ensured that the filament could actually slide into the nozzle. It did, but it was pretty tight. I was eventually able to slide it back and forth in the nozzle a bit and it seemed to loosen up, so I reassembled the nozzle. I struggled a bit to get the nozzle aligned with the extruder head as the printed tool came free from the printer, so I had to fuss around a bit, but eventually got everything lined back up and re-attached. After that, it worked as intended. Filament loaded correctly, and I was able to print without a problem.- As noted above , the nozzle diameter seems just a little smaller than the stock nozzle. Time will tell if I have any further issues with filament not wanting to slide in, but I was able to unload the PLA filament I used to test without issue after printing a benchy.- The benchy I printed in PLA looks good. No noticeable defects.I am happy to have this more durable nozzle in my MK4, and am eager to use it to print some more demanding filaments.

I've been collecting Durozzle nozzles for my various printers for a while now and have had great results with the tungsten carbide (TC) tipped nozzles especially. I haven't ran a whole lot of carbon fiber PETG through this nozzle like I have on my other printers, but looking at this nozzle, its obvious they use the same TC insert as the others, so I imagine the results and outcomes to be comparable.So, as I've found on my other examples, the TC should tolerate abrasive filaments extremely well without no obvious wear even after passing an entire spool. Brass nozzles have always showed significant boring out after a full roll, as have hardened steel. I haven't cut one of these open to see if the inside of the nozzle is also beveled to help with filament flow, but their marketing images show it is, and with their ruby nozzles I have, I can shine a light through it and see evidence of a non-flat insert, so I imagine they're not fibbing about the TC nozzles.The guide tube and copper (brass?) bushing aren't as polished as the marketing photos, but I doubt that's any issue at all.I also like the little cases Durozzle nozzles arrive in. I remove the extra foam inserts and store similar nozzles together......actually that might not be a good idea as I realize I have no idea which nozzles go to which printers now. But I also re-zero after nozzle changes, so it probably doesn't matter. :)
