シリコンカーバイドノズル-K2シリーズ

Received the item within the deadline and all intact, it seems to match the exact size of the original item manufactured by Creality. Once I have used it, will add more reviews.

K2 Plus
Stock Hotend
Upgraded Heated Bed

Observations:
Not exactly what you would call an overly professional reviewer for this. I would still say that I am in the beginner to intermediate phase of understanding 3D printing. So giving a Folsom review of this particular nozzle compared to the stock nozzles that I received with the unit is going to be difficult.

I can say that it doesn't allow pla to stick to the nozzle during printing. Installing is exactly the same as removing the stock nozzles. You will need to apply thermal grease around the heat break just as you would for virtually every nozzle for every 3D printer.

Thus far it's performance is at par if not better. I still need some more time to give a perfect review, but I am extremely happy with the quality of the unit itself.

​If you do a lot of technical 3D printing with abrasive materials like carbon fiber, glass fiber, or wood-filled filaments, you know exactly how fast a standard brass nozzle can wear down and ruin your print quality. I picked up this Phaetus/Creality Silicon Carbide nozzle for my K2 setup, and it has completely transformed my workflow. Right out of the box, the build quality is exceptional. It handles the brutal abrasiveness of technical filaments like a champ, boasting a massive 7X service life increase that gives me total peace of mind during long, overnight print jobs. I no longer have to constantly check my first layer or recalibrate my z-offset due to premature nozzle wear.
​What really blows me away, though, is the incredible thermal conductivity and high-flow capability. Pushing a 30mm³/s max flow rate means I can ramp up my printing speeds significantly without worrying about under-extrusion or extruder skipping, even when melting dense, composite materials. The filament glides through smoothly, and the layer adhesion on my structural parts has been rock solid with zero clogging issues. If you are running a K2 Plus, K2, or K2 Pro and want a heavy-duty, set-it-and-forget-it nozzle that delivers high-speed performance and flawless reliability with engineering-grade filaments, this upgrade is worth every single penny.

This seems to work well and I've had no issues as to the longevity I'm not sure as I have only been using it for about 3 weeks now.

Good ideas can be poorly executed. This is one of them. First the positives - deliver was quick, nicely packed and came with a mouse pad! Now install is quick and easy, the reprogramming of your K2+ easy. But that’s about it. Negatives - cutter issues, retraction issues, feeder issues, on and on and on. I will wait to reinstall it after going back to the OEM. 3/5 if you like tinker it’s worth a try
