Any Thoughts, Ideas or Theories of the Bambu H2D that they have been teasing? (lemmy.blahaj.zone)

Even with all the Controversy that rightfully surrounds them, I still think that this could be well worth Discussing given thier Track Record.

While it is likely just Marketing Jumbo, the Whole "Rethink Personal Manufacturing" stuff does make me think that this double extrusion stuff is more than just 2 Lossless Filament changers. What do you folks think? What will be the Killer Feature of the H2D?

I doubt that it'll really have killer features.

You'll most likely be able to exchange the 2 Hotend-Toolhead for a Laser-Hotend, it'll have a heated AMS, it may have a vinyl-cutter head.

I don't really think I'd want to Laser on my heated bed, or cut on it either. The Fumes from lasering will impact durability of anything in the printer, without really lots of ventilation it will produce lots of dust (well, ash).
Cutting on the same head is weird, as a cutter needs to resist a bit or cutting force.

The dual-nozzle-design is interesting, but I think it's still vastly inferior to multiple toolheads, with anything over 2 materials there is still cutting required. Depending on how they solved the issue with feeding the two hotends, I'm not sure how there won't be quite a bit of added complexity for loading the AMS, where you have to think which head needs which filament.
Using a single extruder gear for both hotends also increases chances and risk of cross-contamination. I've never had a printer who didn't occasionally chew filament.
Moving the Hotends on linear rails, having a mechanical drop-stopper on the hotend all increase complexity, I'm not sure how bad blob of dooms will get here.

If they use their touted servo-design actually on the corexy kinematics, that will be interesting, because conventional wisdom says it doesn't really improve 3d-printing performance. At least not until you get to ridiculous builds (think minuteman)

Cost will be interesting, as apparently the H2D was touted to "be above current X1 line", if that were to include X1E and the $2500 price tag it would be... rather expensive.
But even when it's "just" more expensive than the X1C at $1200/$1450, coming to... idk, $1500 in it's bare configuration, that's rather big chunk of change for a hobbyist. And they will (hopefully) have lost lots of enthusiasts with their firmware-stunt.

Something kinda cool that could theoretically be done would be print smoothing with the laser. Print it, change the tool, laser (at least) the stairstepping on top away.
