5pcs E3D V6 0.4mm 3D Printer Nozzles Hardened Steel Nozzle+Cleaning Needles Tool for Makerbot, Prusa i3, Anet8, Anycubic i3 mega

They work just fine, but because they're not a standard 7mm hex they're extremely difficult to properly install and remove. They only have two flat sides to grip onto, limiting what tools can be used.

I do a LOT of 3D printing. I had been buying regular brass nozzles and honestly they just don't hold up that well. I thought I would give these steel nozzles a try and I was not disappointed. The fit and finish is right up there with the better brass nozzles I have used. Calibration was no different than brass nozzles. Print quality looks good so far. All in all, so far so good. Time will tell how these hold up.

I have used these for a few weeks. I like the fact that I can use it with abrasive material without them wearing quickly. But these aren't my idea of a great solution.I wish these were hex drive instead of 2 flats. Since I can't use a socket, it is more awkward to put them in. And my Prusa frequently detects an out of spec heat load since it takes so long. That turns the printer off and I have to start over. Also, I can't torque them with my torque wrench to the proper tightness. I have to guess.My second complaint isn't with this product, per se. All steel nozzles have a couple of issues. They transmit heat less quickly than brass so you should print a little slower and/or use a slightly higher temperature. And they clog more easily that brass with many filament types. Steel is just a little "stickier".The criticism of this brand is the socket incompatibility. Steel just has fundamental tradeoffs. I am going quit using them due to the hassle. I'll try a jeweled one next. Jewelled nozzles are expensive, but I have wasted a lot of time cleaning and thrown out too many failed prints.

I only have experience with one of them, since they don't seem to fail like brass. My prints have been great. No complaints.

Honestly the best hot end tips I’ve ever bought. They melt PETG like butter, and make pla prints look molded.Easy to use. Make sure your using them for an MK8 clone!!Tech support has always been there. And on point when it comes to answering questions. And making sure I understood what was being said to me. Glad all 13 of my machines are using these as they make all my prints look pro.

The nozzle has been working fine, but they don't have the standard hex heads so I can't install these nozzles using my torque tool.

I purchased these tips to replace my copper tips that kept degrading when using polycarbonate w/ carbon fiber filament and ABS. After using one of the tips for a couple of weeks these seem to be holding up better.

Fast shipping wheels as needed. No complaints

Direkt im ersten Anlauf mit den SIMAX3D Zozzle habe ich mit Carbon und "Glow in the dark" Filament ein sehr gutes Ergebnis.Das Carbon (PETG) von Redline habe ich mit 235°C gedruckt.
