DiamondBack Nozzle for Creality K2, K2 Plus & Hi, 0.4 mm

The E3D DiamondBack Nozzle is an official collaboration between E3D, DiamondBack and Creality, developed specifically for the Creality K2, K2 Plus and Hi 3D printers. With its polycrystalline diamond (PCD) tip, it sets new standards in service life, print quality and material compatibility.

Why diamond?

Diamond is the hardest material in the world, and it is this property that makes it an ideal choice for a 3D printer nozzle. The PCD tip consists of thousands of tiny diamond crystals that are bound into a matrix with direct diamond-to-diamond bonds using a special binder. The result is a nozzle that remains virtually indestructible, even when used with the most abrasive filaments. Whether it's fibre-reinforced materials, metal-filled filaments or ceramic composites, this nozzle can print them all without constant maintenance or concerns about wear and tear.

More precise print results

The solid diamond tip not only significantly extends service life but also noticeably improves printing precision. Compared with a standard nozzle, typical artefacts are greatly reduced, surfaces appear more even, and the overall print result is cleaner.

Long service life

When printing with abrasive filaments, the nozzle tip is the first part to wear. Since the DiamondBack Nozzle is reinforced exactly at this point with the hardest available material, it can withstand even extreme loads over exceptionally long periods.

Smooth surfaces and strong layer adhesion

PCD offers outstanding thermal conductivity. The nozzle transfers heat to the filament very efficiently, improving layer adhesion and producing mechanically stronger parts. In addition, the extremely low coefficient of friction of the polished diamond tip creates ultra-smooth top layers, with an effect reminiscent of classic ironing.

Plug & Print, installation without modifications

The DiamondBack Nozzle is precisely designed for compatibility with the mounting system of the Creality K2, K2 Plus and Hi. No adjustments to the holder or changes to the fan duct are required.
