First-generation product — no release history to base predictions on
Bambu Black Friday 2026 — Bambu's sale runs from October 27 to December 1. The best annual sale event for Bambu printers.
| Model/Config | Build Volume | Speed | Multicolor Type | Best For |
|---|---|---|---|---|
| H2D (standalone) | 350×320×325 mm | 1000 mm/s | Dual nozzle (2 materials, AMS sold separately) | Soluble supports, dual-material production. |
| H2D AMS Combo | 350×320×325 mm | 1000 mm/s | Dual nozzle + AMS 2 Pro included | Dual-material plus multicolor printing. |
Key strengths
The H2D's toolhead carries two nozzles, each with its own material. Switching between them avoids most of the purge waste of single-nozzle filament changes and enables dual-material prints including PVA/PLA soluble support combinations.
350×320×325 mm gives more print area than the standard 256 mm Bambu models — suited for larger professional parts.
The H2D supports a wide range of engineering filaments including PA-CF, PETG-CF, and PC with its enclosed chamber.
The Bambu Lab H2D, launched March 25, 2025, introduced dual-nozzle printing to Bambu's lineup — a single toolhead carrying two nozzles, each loaded with its own material, for soluble supports and two-material prints with far less purge waste than single-nozzle filament switching. It also works with AMS units for multicolor printing, and the AMS Combo includes an AMS 2 Pro. It remains Bambu's active dual-nozzle model, sold in parallel with the single-nozzle H2S and toolchanger H2C, and saw a price drop following the X2D launch.
Both. The H2D has one toolhead with two nozzles, and each nozzle can be fed from AMS units — the AMS Combo ships with an AMS 2 Pro. The two nozzles let you keep two materials loaded (for example PLA with PVA soluble supports) and cut most of the purge waste of switching on a single nozzle, while AMS adds more colors on top. The single-nozzle H2S relies on AMS filament switching alone.
