So far it's been a great nozzle. I've used it with abs and asa, so nothing too harsh, but it prints well so far. 4 starts due to price, as it's a bit expensive. Will be trying some glass or cf filled fibers soon.

I recently purchased the Diamond Nozzle for my custom-built Voron 2.4 3D printer, and I’m absolutely thrilled with its performance! This nozzle is a game-changer for my printing setup. The abrasion-resistant design is top-notch, handling a variety of filaments, including abrasive ones like carbon fiber, with zero issues. It’s incredibly durable, maintaining precision and consistency even after extended use.Installation was a breeze, and it fit perfectly with my Voron 2.4’s hotend. The print quality is outstanding, delivering crisp, clean layers every time. I’ve noticed a significant improvement in reliability and reduced maintenance compared to other nozzles I’ve tried. For anyone running a high-performance printer like the Voron, this nozzle is a must-have. Five stars, hands down!

Installed fine with no leakage. I have multiple Ruby nozzles of this brand for both Prusa and QIDI and they all work well. This one however, was impossible for me to tune - leaked out the (proper) end before and after printing - played with the nozzle temperatures in a wide range without success. 1st layer always poor. Put a Durnozzle Ruby back in and same filament worked perfectly. I sent this back in the return window. My son has one and thinks his works well - same QIDI X-Max 3 printer to be fair (why 3 not 1 star). I have a Tungsten one of theirs in now and it works better, but Ruby still the best.

It is working perfectly so far. Long term use with determine if the diamond was worth the cost.

My husband has one of these on his K1 and he wanted the same for his custom printer. He loves that you can print any filament through it and not have to worry about changing the nozzle out ever again. He prints a lot of Carbon Fibre filaments with his other printer and now he can as well on his custom printer.
