This was posted on Reddit a hours ago. Cutting manual has directions for the H2D and a H2S. It’s the same printer as the leak photo. Does the S stand for single? Could be.

It’s not exactly the same as last leak, hope the first leak is more correct or there’s several variants coming. Specifically what I liked on the first leak was that it had dual filament feeds just like the H2D, even with single nozzle that would reduce time for color change alot since it’s basically just cut and purge and then prepare next color while printing.
While I somewhat, I think it makes more sense from both a cost and complexity (and weight) perspective to eliminate the dual extruder setup and just have it prep the filament to the dual buffer in the back. You still eliminate the (usually) longest part of the path (from the ams to the inside of the machine) this way.
I find it hard to believe they would keep the dual extruder in the H2S merely because of what I mentioned above, specifically cost. If you need/want faster multi material swapping, that is why the h2d exists.
Will this make much difference in price from H2D?
Does this hurt the H2D?

Probably. Im guessing it will hit the advertised speeds of the h2d, while being higher quality. Probably fix whatevers causing the bad layering on the h2d and be less break prone also. Easier to work on and cheaper to fix. Only downside being 2 color prints over a certain layer count. I personally hope theres another toolhead not in the picture. One purges at the end of the x axis, while the other prints. For truely fast multicolor printkng with any number of colors and true multi tpu printing. May only get 300x325, though. I would sell both h2d’s and switch over.
Just wanted to comment on the layering issue, since I brought it up. In my h2d review, I did a benchy that had no hull line visible. In the same review, you can see layering issues on other prints. Its not just a hull line problem. The h2d actually prints perfect benchies wothout a hull line
Im Inn!
Would switch instant.

Bambulabs sucks at keeping secrets
It definitely won’t have dual nozzles.
Well they aren’t called SecretLab and besides, have you ever tried hiding in bamboo?

You’re new to this type of marketing right? haha Try reading about Apple trying to hide “secrets” about iPhones and their iterations… left on Starbucks for example.
Properly functioning H2Ds don’t have such a problem tho. I don’t have a theory on why there are lemon ones but the correct solution would be replacing people’s lemon, fixing whatever manufacturing issues, and/or tweaking the default parameters since many relies on it, not reversing back to more basic designs unless it’s some kind of “too expensive to fix, impossible to manufacture with consistency” issue.
I’ve worked on the cleaning the toolhead and at least imo it’s not really a hassle. (still better than the thermal paste days)
If the leaked image was correct, that it’ll revert back to A1 hotends, then it’s only logical that it’ll have A1’s tiny extruder gear as well, since H2D’s higher max flow required the much bigger gear (and housing). The servo motor could go either way. As a owner of two A1Cs, it’s not bad, but there were some major/minor disadvantages not related to the enclosed chamber/dual nozzles:
- the tiny gear struggles with high intensity batch/large sized printing (bigger plate huh) even with a dedicated fan mod keeping the motor cool;
- a lot more filament grinding when doing the above with abrasive filaments;
- a lot worse flow control when printing anything PETG on big (0.6+) nozzles. This has to do with the viscosity so should apply to other engineering filaments as well.
- less sharp corners (might be a servo motor factor);
- If you want big structural prints fast, have to go with big layer heights, which comes with its sets of disadvantages; H2D can do fast speed + lower layer heights and still archive similar or faster results without said disadvantages.
In other words, batch/big parts printing capacity/consistency/flexibility, big nozzle/high temp filament quality, and some smaller improvements on sharpness/VFA (contingent on manual tuning). I’d say, The big gear + servo + upgraded hotend combo is exactly what a big printer / farm machine would want even with just single color prints, so the prospect of H2S losing much of that seemed disappointing. Of course, none of that means anything to a lemon machine lol.
not sure if they are trying to keep secrets, wouldn’t be surprise if their leaking the information themselves as a marketing scheme
