Description
These premium HotEnds are an official collaboration between E3D, DiamondBack, and Bambu Lab - bringing the most extreme abrasion resistance possible for your H2D, H2C, H2S or P2S printer. E3D are very proud to be the only officially approved manufacturer of aftermarket Bambu Lab HotEnds.
Why Choose Diamond?
Thanks to being made from the hardest material on Earth, the Polycrystalline Diamond (PCD) tipped nozzles on these HotEnds deliver unmatched wear-resistance and versatility compared to all other options on the market. They are composed of thousands of tiny diamond crystals with a proprietary binder that forms a matrix of crystals joined with diamond-to-diamond bonds.
And what does that mean for you? With this upgrade you’re getting ultra-durable nozzles that withstand even the toughest 3D printing challenges. You'll be able to print ANY filament – from fibre-filled to metal and ceramics – without needing to worry about destroying the nozzle and endless maintenance.
Precision Printing
The nozzle’s solid diamond tip also significantly improves the printing precision of the filament so you can expect more aesthetically beautiful prints compared to the stock HotEnd’s output. You heard that right, a SOLID diamond is going to help reduce unwanted print artifacts make your prints as pristine as they can be.

Longevity
When printing with abrasive filaments, the primary wear mechanisms on a nozzle are at the tip. Thanks to being bolstered with the hardest material on earth, these HotEnds can withstand insane amounts of wear which in turn significantly increases their lifespan over any other options on the market. In essence, once you’ve installed this upgrade you won’t have to worry about getting a new one again. Better for your pocket, and the planet.

Smooth and Strong
The PCD used in the HotEnd also provides best-in-class thermal conductivity which improves interlayer adhesion for stronger prints. And to top it all off the low coefficient of friction combined with a polished tip creates ultra-smooth top layers with an ironing-like effect.
Effortless Upgrade
These magnetic HotEnds couldn’t be easier to install. The heater and temperature wires are built into the tool head so all you need to do is unclip the existing HotEnd, slot in the new one and you’re good to go. No physical adjustment to the mount or part-cooling is required.
Buying outside the UK?
Avoid additional charges and lead times by ordering from your local E3D Reseller.
Please note:
- Some filled materials contain particles that are close to, if not larger than, some of the smaller industry standard nozzle sizes, including up to 0.4mm. Attempting to print such materials through these nozzle sizes significantly increases the risk of a jam. Please check your filament manufacturer’s datasheet for recommended minimum nozzle orifice diameter to ensure that the nozzle/HotEnd you choose is suitable for your use case.
