E3D K2/K2 Plus DiamondBack Nozzles, Nozzle Diameter: ⌀ 0.40 mm

The E3D DiamondBack Nozzles for the Creality K2 Series are designed for users who demand exceptional durability, precision, and long-term performance. Featuring a genuine polycrystalline diamond tip, these premium nozzles are built to withstand even the most abrasive filaments while maintaining consistent print quality. As a direct replacement for both the Creality K2 and K2 Plus, they offer a simple yet highly effective upgrade for demanding printing applications. Key Features

• Genuine polycrystalline diamond nozzle tip
• Exceptional resistance to abrasive filaments
• Maintains nozzle accuracy over extended use
• Excellent thermal conductivity for reliable extrusion
• Reduced material build-up and nozzle maintenance
• Compatible with Creality K2 and K2 Plus printers

Engineered for Abrasive Filaments

Printing with carbon fiber, glass fiber, metal-filled, or other abrasive materials can quickly wear down standard nozzles, leading to reduced print quality and frequent replacements. The DiamondBack nozzle features a genuine polycrystalline diamond tip, one of the hardest materials available, providing outstanding wear resistance and significantly extending nozzle life. By maintaining its original geometry even after prolonged use, the DiamondBack nozzle helps ensure consistent layer quality, dimensional accuracy, and reliable performance throughout its lifespan.

Consistent Print Quality Over Time

As conventional nozzles wear, the nozzle opening gradually enlarges, affecting extrusion consistency and print accuracy. The DiamondBack nozzle is designed to resist this wear, maintaining a precise nozzle diameter even after thousands of printing hours. This results in more predictable material flow, consistent extrusion, and repeatable print results, making it an ideal choice for professional users, production environments, and serious enthusiasts.

Excellent Thermal Performance

Unlike many hardened nozzles that sacrifice thermal conductivity for durability, the DiamondBack design combines both. The nozzle efficiently transfers heat to the filament, helping to maintain stable extrusion and smooth material flow across a wide range of printing temperatures and materials. The result is reliable printing performance without compromising on speed or print quality.

Cleaner Printing with Less Maintenance

The polished diamond surface naturally resists plastic adhesion, reducing the build-up of molten material around the nozzle tip. This helps minimise nozzle contamination, improves print consistency, and reduces the need for routine cleaning. With fewer interruptions and less maintenance, users can focus on printing rather than replacing worn components.

Direct Upgrade for the Creality K2 Series

Specifically designed as a drop-in replacement for both the Creality K2 and K2 Plus, the DiamondBack nozzle installs easily without requiring modifications to the printer's hotend assembly. Whether you're printing engineering-grade composites, production parts, or everyday models, the DiamondBack nozzle provides a durable, long-lasting solution that helps maximise printer uptime and maintain outstanding print quality.
