Important features

• Handles abrasive filaments, including metal, ceramic and fiber-filled types

Why choose DiamondBack?

The DiamondBack HotEnd is made from the hardest material on earth – diamond. Thousands of tiny diamond crystals, bonded together with a specially developed binder, form a tip that can withstand materials that would quickly destroy conventional nozzles. Whether you’re printing with fiber-filled, metal or ceramic filaments, this nozzle delivers without compromise.

Precision and quality

The solid diamond tip provides exceptional precision, sharper details and smoother surfaces. The low friction and polished tip ensures consistent extrusion and top coats that look almost smooth.

Built for longevity

Unlike brass or hardened steel nozzles, DiamondBack is designed to last indefinitely under normal use. Once you upgrade, you no longer have to worry about wear and tear and frequent replacements – saving both money and resources.

Easy upgrade

Installation is incredibly simple. The HotEnd is magnetically mounted with integrated heater and temperature sensors. Simply click the old one off, insert the new one, and you're ready to print – without any further adjustments.
