Bambu Lab’s H2D and H2S share the same chassis, the same roughly 340mm-class build volume, and the same 65°C heated chamber. They ship in the same generation for a reason: the H2S is the H2D with one part removed. Here’s whether that one part — a second nozzle — is worth $650 to $800 to you.
Bambu Lab H2D vs H2S by the numbers
- 1 nozzle vs 2 nozzles — the entire mechanical difference between the two machines, per Bambu Lab’s own spec sheets. Every other core spec is shared.
- $1,249 vs $1,899 — the solo starting price, a $650 gap for the second nozzle alone.
- $1,499 vs $2,199–$2,299 — the AMS 2 Pro Combo price, a $700–$800 gap at the multi-material tier.
- 340×320×340 mm vs 350×320×325 mm — build volume is essentially a wash; the H2S is slightly taller, the H2D slightly wider, per Bambu Lab’s spec sheets.
- 65°C / 350°C on both — heated-chamber and hotend ratings are identical, so carbon- and glass-fiber composites print the same on either machine.

| Laser Full Combo | ~$2,799 (10W) / ~$3,499 (40W) | $2,099 (Laser Full Combo) |
| Best for | Regular multi-material prints with soluble/breakaway supports | Everything else — same chassis for $650–$800 less |
Bambu Lab H2S: the same chassis, minus one nozzle
The H2S exists to prove the H2D’s build volume and heated chamber don’t require its price tag. At $1,249 solo, it prints a 340×320×340 mm volume — actually taller than the H2D’s 350×320×325 mm — and matches its 65°C actively heated chamber and 350°C hotend exactly, per Bambu Lab. That means carbon- fiber nylon (PA-CF), glass-fiber nylon (PA-GF), PC-CF, and PPS-CF all print without the warping and delamination that trips up passively enclosed machines like the P1S or P2S, on either the H2D or the H2S.
Bambu Lab H2S
- 340×320×340 mm build volume, 65°C heated chamber, 350°C hotend.
- 1,000 mm/s rated toolhead speed — identical to the H2D.
- $650–$800 cheaper than the equivalent H2D tier for nearly the same machine.

Bambu Lab H2D: the second nozzle, for a price
The H2D’s entire reason to exist over the H2S is its second, independently-driven nozzle. One nozzle carries your model’s structural filament while the other dedicates itself to a soluble (PVA) or breakaway support material — eliminating the purge waste a single-nozzle system like the H2S generates every time it switches materials mid-print. That’s a real, measurable savings for workflows that use dissolvable supports regularly; it does nothing for ordinary multi-color printing, which the AMS 2 Pro Combo handles the same way on both machines.
Bambu Lab H2D
- Two independently-driven nozzles cut purge waste on multi-material prints.
- Same 350×320×325 mm build volume, 65°C chamber, and 350°C hotend as the H2S.
- $650–$800 more than the H2S for the second nozzle alone.
How to choose between the H2D and H2S
- Do you print soluble or breakaway supports on a regular basis? If yes, the H2D’s second nozzle pays for itself over time in reduced filament waste and cleaner prints. If your multi-material needs are occasional, or you’re really just switching colors, the AMS 2 Pro Combo on the cheaper H2S covers that already.
- Does $650–$800 matter more to you than convenience? Since build volume, chamber temperature, and hotend rating are identical, that premium buys exactly one feature. For most hobbyists and prototypers, the H2S is the better default; the H2D earns its price only for a specific, recurring workflow.
For nearly everyone printing large-format or high-temperature parts, start with the H2S — it delivers the same core machine for hundreds less. Reach for the H2D specifically when soluble- support multi-material printing is a real, frequent part of your workflow, not a one-off.
Bottom line
The Bambu Lab H2D and H2S are the same large-format, heated-chamber printer wearing two different price tags. The H2S matches the H2D’s build volume, 65°C chamber, and 350°C hotend for $650–$800 less, giving up only the second nozzle’s purge-waste savings on soluble-support prints. Buy the H2S by default; step up to the H2D only if that specific multi-material workflow is one you run often enough to justify the premium.
