Consistent extrusion at high speeds

I run my K1 at maximum speed and this nozzle maintains consistent extrusion without clogging. The brass core ensures good thermal conductivity while the steel exterior provides durability.

Great quality, easy install

Installation was straightforward and took less than 10 minutes. Print quality is excellent. I deducted one star only because the packaging was slightly damaged upon arrival, but the product itself was fine.

Saved my print head

I accidentally ran abrasive filament through a standard brass nozzle and ruined it. This hardened steel replacement is much more forgiving and has lasted months so far.

Best value for money

Compared to original parts, this offers the same performance at a better price point. My PLA and PETG prints look smoother than ever.

Perfect upgrade for carbon fiber prints

This hardened steel nozzle handles carbon fiber filament without any wear after 2kg of printing. The high-flow design really speeds up my production time on the K1 Max.

Solid performer

Works exactly as described. The high-flow capability is noticeable when printing large volumetric parts. Just make sure to recalibrate your flow rate after installation.

5 FAQ

Q: How often should I replace this nozzle if printing PLA only?

A: If you are only printing non-abrasive materials like PLA, this hardened steel nozzle can last significantly longer than brass nozzles, often upwards of 6-12 months depending on usage hours.

Q: Does this come with a heater cartridge and thermistor?

A: This package includes the print head block and the nozzle. It does not include a new heater cartridge or thermistor; you should reuse your existing ones if they are in good condition.

Q: Is this nozzle compatible with the standard Creality K1 non-Max version?

A: Yes, this print head assembly is fully compatible with both the Creality K1 and the K1 Max models.

Q: What is the recommended temperature range for this nozzle?

A: The nozzle is rated for temperatures up to 300°C, making it suitable for most engineering filaments including ABS, ASA, PC, and Nylon.

Q: Can this handle glass-filled nylon filaments?

A: Absolutely. The hardened steel construction is specifically designed to resist abrasion from composite filaments like glass-filled nylon and carbon fiber.
