Bambu Lab H2S vs Bambu Lab P1S
Technical comparison · Fused filament fabrication (FFF/FDM)
Choose Bambu Lab H2S if you need a larger build volume (340×320×340 mm) and extrusion temperatures up to 350 °C for advanced materials. Choose Bambu Lab P1S if you are looking for a compact, budget-friendly machine capable of handling up to 16 colors for standard prints.

| Software notes | The H2S uses Bambu Studio as its primary slicer, with full support for proprietary features including automatic calibration, AI monitoring, and AMS management. It also accepts G-code exported from OrcaSlicer, PrusaSlicer, and Cura, though some advanced functions may not be available with third-party slicers. Laser and cutting functions are managed exclusively through Bambu Suite. Developer Mode is available, exposing MQTT access for custom integrations. | The P1S is managed through Bambu Studio, Bambu Lab's proprietary slicer available for Windows, macOS, and Linux, or via OrcaSlicer, the widely adopted open-source fork that provides finer parameter control. The Bambu Handy mobile app enables remote monitoring and print launching. The printer supports local LAN connections without a mandatory cloud account, though some advanced features — such as remote timelapses and OTA firmware updates — require a Bambu account. |
The differences that matter
- Build volume and footprint: The H2S offers a print area of 340×320×340 mm compared to the P1S's 256×256×256 mm, but weighs more than twice as much (30 kg vs 12.95 kg).
- Maximum speed: The H2S reaches 1000 mm/s, doubling the 500 mm/s of the P1S.
- Operating temperatures: The H2S nozzle reaches 350 °C and the bed 120 °C, whereas the P1S stops at 300 °C and 100 °C, respectively.
- Cost: The P1S is priced at ~399–499 €, making it much more economical than the ~1150–1250 € range of the H2S.
Which one to choose
Choose H2S if…
Choose Bambu Lab H2S for applications requiring a peak speed of 1000 mm/s and a build volume of 340×320×340 mm. Its 350 °C extruder, combined with a 120 °C bed, enables the use of more demanding polymers, justifying the ~1150–1250 € price tag.
Choose P1S if…
Choose Bambu Lab P1S for reliable and affordable (~399–499 €) intermediate use in a confined space. The 256×256×256 mm volume and operating temperatures (300 °C / 100 °C) are suitable for most filaments, printing at up to 500 mm/s.
