💡About the Bambu Lab H2S
The Bambu Lab H2S, announced August 26, 2025, is Bambu's largest single-nozzle printer — succeeding the H2D with a 340×320×340 mm build volume (220% the volume of the X1C), 1000 mm/s peak speed, and active 65°C chamber heating. Unlike the dual-nozzle H2D it replaces, the H2S uses AMS 2 Pro for multicolor printing, supporting up to 24 filaments across multiple AMS units.
- 340×320×340 mm — Bambu's largest build volume
The H2S offers 220% the print volume of the X1C. At 1000 mm/s it is also Bambu's fastest printer, making it the top choice for high-throughput professional production.
- Active 65°C chamber heating
The enclosed chamber with active heating handles the full engineering filament spectrum — ABS, ASA, PA, PA-CF, PC, and PPS — with consistent results across the full build plate.
- Up to 24-color AMS multicolor
The H2S supports up to 12 AMS units (4 AMS 2 Pro + 8 AMS HT), enabling 24-filament printing for large-format multicolor production.
🎯Who is this for?
Professional makers and studios who need Bambu's largest enclosed build volume for high-throughput production, engineering materials, and optional AMS multicolor — without the complexity of dual-nozzle printing.
❓FAQs
H2S vs X1C — which professional Bambu printer should I buy?
The H2S has a 220% larger build volume (340×320×340 vs 256×256×256 mm) and prints at 1000 mm/s vs the X1C's 500 mm/s. The X1C adds LiDAR first-layer scanning and AI spaghetti detection — useful for unattended printing on complex jobs. For maximum volume and speed, the H2S. For the best monitoring and reliability on high-value prints, the X1C.
Is the H2S a dual-nozzle printer?
No — the H2S is single-nozzle. The 'S' in H2S stands for single. It replaced the dual-nozzle H2D with a single high-speed nozzle and AMS 2 Pro compatibility for multicolor. If you specifically need dual-nozzle printing (for true simultaneous two-material output), look at the Bambu H2C instead.
How does the H2S compare to the H2D it replaced?
The H2D used dual nozzles printing simultaneously — ideal for soluble supports and no-waste two-material prints. The H2S switches to a single high-performance nozzle at 1000 mm/s with AMS multicolor support. The H2S is larger, faster, and more capable for most high-volume workflows. If true dual-extrusion is essential, the H2C (Bambu's toolchanger at $2,399) fills that role.
Can the H2S print PA-CF and engineering composites reliably?
Yes. The active 65°C chamber, 350°C hotend, and support for hardened steel nozzles make the H2S one of the most capable consumer printers for PA-CF, PETG-CF, and PPS. The build volume advantage over the X1C makes it particularly suited to large engineering parts.
