H2S

Last updated

Bambu Lab H2S

A different tier entirely. 1,000 mm/s, 350°C hotend, 65°C actively heated chamber, and a build volume that finally gives you real room. The H2S is the single-nozzle way into Bambu's engineering tier.

Should I buy the H2S?

Yes, if you print high-temp engineering materials: with the 350°C hotend and active 65°C chamber, Bambu's filament list adds PPS and fiber-filled PPS, and the heated chamber cuts warping on PC and other warp-prone grades (a capability shared with the H2D and H2C). For PLA/PETG/ABS/ASA, the P2S at $449 is a better fit.

Who should buy the H2S?

  • Engineering materialsGood fit

    A 350°C hotend and an actively heated 65°C chamber for warp-prone engineering filament, in a 340 × 320 × 340 mm build volume. X2D vs H2S

  • PLA, PETG, ABS and ASALook elsewhere

    The enclosed P2S prints all four; the H2S earns its price with 350°C materials and size. P2S vs H2S

  • Two materials or soluble supportsLook elsewhere

    The H2S has one nozzle; the H2D carries two on the same toolhead. H2S vs H2D

  • Laser engravingDepends

    Takes Bambu's 10W laser and the cutting module; the 40W laser kit is only offered for the H2D and H2C. H2S vs H2D (Bambu store)

Known issues

  • PTFE tube detachment detection is temporarily disabled; Bambu lists it as a known issue of the current firmware 01.02.00.00. (Bambu release notes)

Known issues only from Bambu's own wiki, firmware release notes, FAQ, blog and recall pages, checked October 2, 2026. Specs: our table above and Bambu's spec pages.

Verdict

The H2S is a fundamentally different machine from everything else in Bambu's lineup. The combination of 350°C hotend, 65°C actively heated chamber, and 1,000 mm/s print speed adds materials Bambu does not list for its current 300°C printers, such as PPS and fiber-filled PPS, and gives PA-CF, PC blends and other engineering polymers sustained chamber heat instead of a passive enclosure.

It launched in August 2025 at $1,249, just $50 above the X1 Carbon (the X1C is discontinued since March 2026, superseded by the X2D), and now sells for $1,049 in the Bambu US store. For that money: faster print speeds, higher-temperature hotend, active heated chamber, and a larger build volume. The X1C's Lidar quality sensing was the only reason to pick it instead, and with the X1C out of the lineup that choice no longer applies to new purchases. The H2S is heavy (30 kg) and draws up to 2,050W at 220V (1,170W on 110V models). For PLA and PETG it's overkill, but for engineering parts it's the right tool.

Pros & Cons

Pros

  • 350°C hotend: PPS and fiber-filled PPS on top of PC and PA-CF
  • 65°C active heated chamber: reliable engineering prints
  • 1,000 mm/s: Bambu's top speed (shared with the X2D and the other H2 models)
  • 340 × 320 × 340 mm: large, useful build volume
  • Hardened steel nozzle stock
  • Up to 24 colors (4× AMS 2 Pro + 8× AMS HT)
  • 3-stage filtration: G3 pre-filter, H12 HEPA, activated carbon

Cons

  • Heavy at 30 kg, not portable
  • Up to 2,050W draw at 220V (1,170W at 110V), check your circuit
  • No Lidar (X1C has this)
  • No dual nozzle (H2D has this)
  • Overkill for PLA/PETG printing
  • AMS 2 Pro / AMS HT sold separately

Material compatibility

Filled circle: works well. Half: capable, or only with upgrades. Empty: not recommended.

MaterialSupportNotes
PLA / PLA+WorksOpen the door partially for cooling. Overkill but functional.
PETGWorksFine, but the H2S is not the machine for PETG day-to-day.
ABS / ASAExcellentThe active chamber makes these even more reliable than on P2S.
PA-CF (PA12-CF, PA6-CF)ExcellentThis is what the H2S is designed for. Reliable with 65°C chamber.
PC (Polycarbonate)Supported350°C hotend + active chamber suit PC well. Dry filament required.
PC-CF / PC-ABSSupportedHardened nozzle stock helps. Good results.
PA6-GF / PA12-GFExcellentGlass-filled nylons work well here.

PEEK / PEI / ULTEMNot listedNot on Bambu's H2S filament list. Check the filament maker's specs before trying.

Setup tips

Pre-heat protocol
For engineering materials, set chamber target to 65°C and wait until it is reached before starting the print. Let the temperature stabilize for 5 minutes. Parts printed with a pre-heated chamber have consistently better adhesion.
Dry filament
PA-CF and PC are hygroscopic. Always dry filament before printing (75–85°C for 8–12 hours, per Bambu). Moisture causes popping, stringing, and poor layer adhesion, even the best chamber won't fix wet filament.
Power
The H2S draws up to 2,050W at 220V (1,170W at 110V) while the bed heats up. Verify your circuit can handle this, especially if other equipment is on the same breaker.
Network
The H2S connects over dual-band Wi-Fi (2.4 and 5 GHz). In the H2 series, Bambu lists a wired Ethernet port only for the H2D Pro, so plan for good Wi-Fi coverage in the workshop.

Common questions

H2S or X1C?

H2S. The X1C is discontinued since March 2026 (superseded by the X2D), so it is no longer a new-purchase option. The H2S is faster, larger, higher temp, and has an active chamber; a used X1C only makes sense if Lidar quality sensing is specifically what you need.

H2S or H2D?

H2S if single-material engineering parts or multi-color via AMS is sufficient. H2D if you need dual-nozzle printing (soluble supports, dual-material parts) or the higher-power 40W laser. The H2S also takes the optional 10W laser and cutting module.

H2S or P2S?

P2S ($449) covers ABS/ASA and, on Bambu's filament list, PC and carbon-filled nylons too. H2S ($1,049) if you need a 350°C hotend and an active 65°C chamber (among current models, only the H-series lists PPS), or the larger build volume.

Is 1,000 mm/s usable?

It is Bambu's rated maximum toolhead speed. Acceleration is 20,000 mm/s², the same as the P1S and P2S, so how much faster a real print finishes depends on the model, material and quality settings.

Starter accessories for the H2S

What we would add to a new H2S in the first month.

  • SUNLU FilaDryer S2

    SUNLU FilaDryer S2

    The H2S targets engineering materials. SUNLU rates the S2 for 70°C: enough for PLA, PETG and TPU; nylon only with long runs. For frequent PA or PC, a dryer that reaches 85°C, such as Bambu's AMS HT, fits better. S2 or S4

    Amazon

  • PRILINE Carbon Fiber PC

    PRILINE Carbon Fiber PC

    Carbon-fiber PC (use the PC profile) that makes use of the H2S's 350°C hotend and hardened drive train. Stiff, light functional parts.

    Amazon

  • Creality Vacuum Storage Kit

    Creality Vacuum Storage Kit

    Opened engineering spools degrade fast in room air. Vacuum-seal them between H2S jobs.

    Amazon

  • Capricorn PTFE Tube XS

    Capricorn PTFE Tube XS

    Capricorn XS, 1.9 mm ID. Bambu specifies 2.5 mm ID tubes for the H2S (2.0 mm inside the AMS units) and advises against a smaller ID because it adds friction. In our own printers it has still worked better than the stock tube, which is why we keep recommending it; if feeding gets worse, go back to the stock size.

  1. Dryer note corrected: SUNLU rates the FilaDryer S2 for 70°C, enough for PLA, PETG and TPU, nylon only with long runs; for frequent PA or PC, a dryer that reaches 85°C, such as Bambu's AMS HT, fits better.
  2. Spec table: layer height is now 0.08 to 0.28 mm, the Bambu Studio default range for the 0.4 mm nozzle (was 0.05 to 0.35 mm).
  3. PTFE tube note: Bambu specifies 2.5 mm ID tubes for the H2S (2.0 mm inside the AMS units) and advises against smaller ones; we now say why we still recommend the 1.9 mm Capricorn XS.
  4. Added Who should buy, Known issues (Bambu sources only) and the firmware and price lines; AMS support now up to 24 colors with AMS 2 Pro and AMS HT units (was 16). Estimated accessory prices removed.
  5. Ethernet removed: in the H2 series Bambu lists a wired port only for the H2D Pro; filament drying now 75 to 85°C for 8 to 12 hours, per Bambu (was 80°C for 6+ hours).
  6. Corrected: HEPA filter listed again (removed by mistake on Jul 31) as a 3-stage filter with G3 pre-filter, H12 HEPA and activated carbon; weight 30 kg (was about 32 kg), power up to 2050W at 220V (was 1500W).
  7. Verdict now gives the October 2025 launch at $1,249 and the current price of $1,199 in the Bambu US store.
  8. Starter accessories: the filament pick is now PRILINE Carbon Fiber PC (was Carbon Fiber PETG).
  9. H2S price in the P2S comparison answer now $1,199 (was $1,249).
  10. Filter spec changed to activated carbon only, no HEPA (was listed as HEPA plus carbon).
  11. Price now $1,199 (was $1,249).
  12. Laser option added: the H2S takes the optional 10W laser and cutting module, sold separately; the H2D comparison names the H2D's higher-power 40W laser.
  13. Added a starter accessories section (filament dryer, carbon-fiber PETG, vacuum storage, PTFE tube); the X1C answer now says the X1C is discontinued since March 2026, superseded by the X2D.
  14. Verdict corrected: reliable printing of PA-CF, PC and other high-temp materials is no longer described as unique to the H2S; the H2D and H2C share that capability.
