Works With Your Prusa Nozzle E3D DiamondBack - 0.4 mm
Why Choose Diamond?
These premium DiamondBack Prusa nozzles bring you the most extreme Nextruder Nozzle solution to date, designed and optimised in collaboration with E3D.
The rapid development of fibre, metal and ceramic filaments has increased the need for abrasion-resistant nozzles. Compared with all the nozzle options on the market, DiamondBack’s diamonds deliver unmatched wear-resistance and versatility.
Smooth and Hard. Unlock extreme wear resistance thanks to DiamondBack’s Polycrystalline Diamond (PCD) tips. These diamonds are composed of thousands of tiny diamond crystals with a proprietary binder that forms a matrix of crystals joined with diamond-to-diamond bonds. They retain the hardness properties of diamond whilst reducing the inherent brittleness of a single-crystal diamond, making them a fantastic choice for printing with engineering grade metal and ceramic-filled filaments.
Precision Printing. DiamondBack nozzles rely on a solid diamond tip to improve precision 3D printing. The tip is not a diamond coating, but rather a solid diamond insert made from the hardest material in the world.
Longevity. The PCD used in these Prusa Nextruder Nozzles significantly extends nozzle life. It provides best-in-class thermal conductivity which improves interlayer adhesion for stronger prints, and the low coefficient of friction combined with a polished tip creates super smooth top layers with an ironing-like effect.
Effortless Upgrade. These HotEnds are a drop-in replacement for your stock Prusa Nextruder Nozzle, no adjustment to the mount or part cooling is required.
