The “H2S Combo” from Bambu Lab is a high-performance desktop 3D printer designed for larger builds, advanced materials, and optional multi-filament / multi-colour workflows. It’s part of their H2 series and represents a step up from their smaller models. Here’s a detailed breakdown of its features and specifications.

Key Features:

• Large build volume of 340 × 320 × 340 mm.

• Single-nozzle (as opposed to dual-nozzle) architecture, making it simpler while retaining high performance.

• Heated/chamber environment: max chamber temperature up to ~65 °C, enabling better printing with engineering materials that benefit from a warmer environment.

• Hotend temperature up to 350 °C, enabling printing of a wide range of advanced filaments (PC, PA, PPS, glass/CF-filled, etc).

• Max heated bed (heatbed) temperature around 120 °C.

• High speed / acceleration: toolhead max speed up to ~1000 mm/s and acceleration up to ~20,000 mm/s².

• Built-in cameras and sensors: The H2S is equipped with a “Live View Camera” and “Toolhead Camera” (and BirdsEye camera in Laser edition), as well as many sensors for monitoring filament feed, nozzle condition, print failure detection, etc.
  

• Multi-material / multi-colour capability via optional system (like an AMS unit) in the “Combo” configuration. This allows switching filaments/spools mid-print.

• Good material versatility: supports PLA, PETG, TPU, ABS, ASA, PC, PA, PET, PPS, plus carbon/glass-fibre reinforced versions of some of these.

• The “Combo” version adds the filament handling system (AMS) on top of the base printer, so you get the multispool capability.

• Optionally, there is a Laser edition (for cutting/engraving) but that may be separate from the standard Combo.

Technical Specifications:

Here are more detailed specs for the H2S (from the manufacturer/news sources):

• Printer physical dimensions: ~492 × 514 × 626 mm³ (for H2S) and net weight around 30 kg.

• Max nozzle temperature: 350 °C.

• Max bed temperature: 120 °C.

• Chamber (enclosure) temperature: up to ~65 °C.

• Max toolhead speed: ~1000 mm/s; max acceleration ~20,000 mm/s².

• Nozzle diameters supported: 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm.

• Filament diameter: 1.75 mm. (Standard for Bambu Lab machines)

• Materials supported: PLA, PETG, TPU, PVA, BVOH, ABS, ASA, PC, PA, PET, PPS; carbon/glass fiber reinforced versions of many of these.
