TL;DR E3D and Bambu unveil a HotEnd that allows you to print 60% faster with your Bambu X1 and P1 Printers. Read more to find out how it came to be, and to find out the full specifications!
When we first got our hands on the Bambu X1 printer, we were delighted by its overall performance, and blown away by the speed of its motion system. However, as we started to push the printer to its limits, we found ourselves bumping into the melt flow rate limit of the HotEnd.
We had just launched E3D Revo High Flow off the back of some fastidious research into the perfect internal geometry to deliver maximum flowrates in small packages: it was obvious that we should try our hand at “upgrading” the X1.We designed a version of the Bambu HotEnd that made use of E3D’s High Flow geometry, quickly manufactured the prototypes in our in-house workshop, fitted them onto the rather un-suspecting Bambu printer that we had in the workshop, and delighted ourselves with the performance improvements.
We were able to hit flowrates >60% higher than standard, which enabled us to push the productivity of the Bambu X1 to new heights.It would be an understatement to say: we were excited to be able to bring these improvements to the "Consumer printer of the year" (2023 3DPI awards).
When we visited Bambu in July 2023, we took some of our samples along and left them with Dr Tao, we agreed that if the product lived up to our claims it surely had the potential to delight his users. To get the project moving, Dr Tao dedicated some highly proficient members of his team (including project managers and engineers) to help us bring a product to market that would meet both Bambu and E3D’s quality standards and delights our customers.
High Flow + ObXidian!
From the initial sample handed to Dr Tao, we enhanced the specification to include a hardened steel High-Flow insert (we initially prototyped using brass), a copper heater block (versus the brass Bambu use), and topped it all off with an ObXidian coating to ensure that the new product was in no way a regression on the standard Bambu design, and instead pushed the envelope in every way.
The product is higher flow, more wear resistant, and many plastics will build up less on the nozzle.

An easy upgrade
“ …pushing the boundaries of what our printers can achieve” Dr Tao, Bambu Lab CEO.
Upgrading to the E3D ObXidian HF Bambu Hotend is designed to be very easy. You do not need to make any modifications to the firmware, mount, or part-cooling fan; and you can reuse the existing temperature sensor and heater pads from the stock Bambu Hotend.
The E3D ObXidian High Flow Bambu HotEnd comes in nozzle diameters of 0.4 mm and 0.6 mm. The Bambu team supply us HeatSinks that are engraved to make it very clear which product is which, and to differentiate this product from the standard Bambu HotEnd. .

With the finalised design, approved by Bambu, we moved onto production: We buy HeatSinks from Bambu; we manufacture the Nozzles and Inserts; then we assemble them together here in Oxfordshire.
We are delighted to bring you this product, and hope it delights you as much as it does E3D and Bambu.
We are very grateful for Bambu's support and are proud that we have been able to make meaninful improvements to their already excellent products. A huge thank you to the team at Bambu, it's been great working with you, and I look forward to our next collaboration!
Yes, you can! The ObXidian coating is designed to withstand the force of a cold pull, however it can be a little bit challenging compared to a typical nozzle as the printer cuts filament very close to the heatsink. While it is possible to clear blockages using the cold pull method, it is not always possible with the Bambu Lab printers. We recommend following the Bambu Lab procedure to unblocking the nozzle.
There are no material limitations. Any material that can be printed with Bambu Lab hardened steel nozzles, our Revo and V6 ObXidian nozzles can be printed with the ObX HF nozzle, and faster.
No, you don’t need to!
These Hotends are designed to maintain the exact same form factor as the stock Bambu nozzles and are therefore not compatible with the revo range of nozzles. If this is something you are interested in, we recommend you have a look at the Revo Panda, a Revo compatible hot end by Biqu.
