New Bambu Lab H2D 3D Printer details finally leaked!

Dec 7

Bambu Labs new and upcoming “flagship” 3D Printer is just around the corner. It’s been postponed to 2025, but already some very credible details seems to have been leaked.

Let us analyse and discuss the leaked image, and what it indicates.

This appears to be a document to be inserted into the new Bambu Lab H2D 3D Printer that has a picture of the actual machine. There are some obvious things that we can read and see directly.

Please note that the image hasn’t been confirmed by Bambu Lab, so we don’t know if it’s real. It looks very credible. But from it, we can extract a lot of knowledge and thoughts. These are all based on the leaked image.

There are TWO nozzles inside! And they seem to be on the same gantry. Let’s discuss that a further down.

We can also see there is a new AMS 2 Pro which is probably a redesigned AMS with a PRO-approach for those two nozzles. I would argue X and P-users will get some sort of AMS 2, with more features/reliability/serviceability in a near future as well.

Looking at the AMS, it’s much smaller compared to the 3D Printer when compared to a X1, meaning the Bambu Lab H2D has a bigger build volume.

Overlaying a Bambu Lab X1C, it appears the Bambu Lab H2D is larger, but assymetricly so with X and Y axis being the same, while Z is higher.

Bambu Lab H2D Combo Build size

If we place a Bambu Lab X1C on top of the H2D 3D Printer and to try align it. We can take the known build size and estimate the additional, which isn’t really 1/3, but looks closer to 50-80mm larger in one axis. If we apply some “bambu Lab numbers” to the build plate I would assume it’s between 325 to 333 mm in X/Y. However, it does look like it’s a bit taller than the X1C, meaning we could see 333 x 333 x 366 (where 366 is in Z).

Dual Nozzle Bambu Lab 3D Printer

If we enhance the Nozzles, it appears there are two nozzles at different heights. This would indicate to me that we’re getting something similar to Ultimaker S3/S5 design. These have one rigid and one moving nozzle, that can be either lower or higher than the rigid nozzle. It swaps height by using a mechanical maneuver to “flip a switch” which H2D could do in the nozzle-wiping movement.

This design works well, but was quite slow on the Ultimaker 3 that I used. With the newer era of 3D printers, it’s probably much faster than a full AMS-purge cycle, and would save on waste as well. While not being as fancy as a full IDEX system.

Exect for purge (AMS changing material) speed increase, this design could allow you to use different printing temperatures, nozzle sizes and types depending on needs. For example one all-metal hotend for engineering materials at high temperatures while the other is optimized for support-material at other temperatures.

*A Bambu Lab Patent for something that looks like a AMS-hub with 2 outputs.*

Having a look at this patent of an AMS-hub (or similar) we see two outputs. There is also a motor to switch “tracks” and/or cut filament.

With some imagination, we could see how this would use two materials into the H2D Combo 3D Printer and run it to either nozzle, meaning you could potentially swap colors only by a simple retraction command, while the AMS can purge the other material while you’re still printing at full speed.

This would speed up multi-color printing immensely!

January 2025 updates

We’ve also seen this image leaked, which appears to show two filament tubes going into the extruder/hot end. Whats weird is that the tubes have different colors.

It could be some accessibility reason. For example if you’re not using an AMS, the colors might help indicate which spool holder goes to what extruder.

This image adds to the speculation of a dual-nozzle system as mentioned earlier.

Is this the 3D Printer we wanted?

If this is the new Bambu Lab flagship 3D Printer it definitely looks like a great evolution of the X1 series. We’re getting a bigger build volume and what appears to be a new multi-material upgrade in terms of nozzle design and AMS. We' expect features from all other Bambu lab printers, like the easy-to-swap A-series nozzles, X1-series sensors/AI and X1E temperature to also make into the H2D.

Looking at the “competition”, H2D doesn’t seem to be as large as the Creality K2 Plus 3D Printer, while it’s closer to Prusa XL, which may be the two only relevant competitors.

The Creality K2 is just big(bigger?) and potentially cheaper. Although a ton of users seems to be happy with the K2 Plus, Creality don’t have the same reputation of reliability and support as the others.

The Prusa XL with 2 (or more toolheads) is potentially bigger, but probably a bit less refined and might cater a bit more to those who want control, upgradability and custom features. Where Bambu Lab has been more “plug-n-Play”.

Theoretical Bambu Lab H2D Combo Pricing

Looking at the current top Bambu Lab 3D Printer, the X1E’s pricing, which currently is $2499 I would expect the H2D to have be the same or higher, here’s why.

Bambu Lab knows that there are ton of professional users with deeper pockets ready to throw money at a “bigger X1”.

The Prusa XL with 2 extruders (and prebuilt + enclosure, which is the target customer group) is $3,469 (5% discounted) which still leaves a lot of room for Bambu Lab to crank the price even more.

The Creality K2 Plus is “only” $1499 at 350x350x350mm with CMS (Crealitys AMS) combo. This is a very budget-friendly price, but you’re not getting the dual nozzles and overall Bambu Lab performance, so I would assume they will dare to price themselves quite a lot higher.

If we’re not getting the “engineering” compatibility that X1E offers, a very aggressive price could be $1999 for the H2D Combo, which would be incredible, and very reasonably compared to X,P and A series features. If the H2D Includes build chamber heating and “engineering-grade” hotends, it’s reasonable that it’s more expensive than the X1E at around $2799-2999.

Potential Lower End versions?

Could we see the H2D body being used for a P or X-series budget printer as well? I’m sure that there could be a configuration with cheaper motherboard, single extruder/hotend gantry with other features removed to allow for a cheaper model. The question is if the H2D design is the optimal for this, or a bigger A-series 3D Printer is better to develop for making it cheap.

Bambu Lab already made an A-series “bed slinger” as it was cheaper to produce for the masses. If we’re getting something big for “enthusiasts” I’m betting it’s an open A-series design.
