The Bambu Lab H2S is the next-generation large-format single-extruder 3D printer in the H-series lineup.
Engineered for high precision and speed, it combines a 350 °C hotend, a 65 °C actively-heated chamber, and a generous 340 × 320 × 340 mm build volume.
The H2S supports optional laser engraving and cutting modules, transforming it into a versatile all-in-one fabrication platform that merges creativity and productivity.


Key Features

  
Large Build Volume – 340 × 320 × 340 mm printing area for bigger and more complex projects.
  
High-Temperature Printing – 350 °C nozzle and 120 °C heated bed for engineering-grade materials like ABS, ASA, PA and carbon-fiber composites.
  
65 °C Active Chamber Heating – Improves layer adhesion and reduces warping on large models.
  
Simplified Single-Extruder Design – Reduces maintenance while maintaining industrial-level performance.
  
Optional Laser Engraving / Cutting Upgrade – Add a 10 W laser for engraving or cutting tasks.
  
High-Speed Motion System – Up to 1000 mm/s movement and 20 000 mm/s² acceleration for faster prints.
  
Precision Safety & Monitoring – Includes door, flame and emergency stop sensors for safe operation.
