Bambu Lab H2S vs Prusa Research CORE One+
Technical comparison · Fused filament fabrication (FFF/FDM)
Bambu Lab H2S and Prusa Research CORE One+ cost nearly the same (about €1200 vs €1199) and both sit at F2, but they start from different premises: build volume against system openness. The choice comes down to what matters more in your workflow.

| 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. | Natively compatible with PrusaSlicer (based on Slic3r, open-source), but it works with any slicer able to generate Marlin-flavored G-code, such as Cura, ideaMaker or Simplify3D. The firmware is a Prusa-modified Marlin 2, fully open: no lock-in to proprietary software or protocols. The user has full control over the machine, but PrusaSlicer is recommended for optimal performance, as it includes exclusive profiles and features like dynamic flow calibration. |
The differences that matter
- Build area: H2S 340×320 mm vs 250×220 mm on the CORE One+ — nearly double.
- Z-height: 340 mm on the H2S vs 270 mm on the CORE One+.
- Nozzle temperature: 350°C on the H2S vs 290°C on the CORE One+.
- Firmware openness: the CORE One+ runs open Marlin with no slicer lock-in; the H2S performs best inside the Bambu Studio ecosystem.
Which one to choose
Choose H2S if…
Pick the H2S for large parts: a 340×320 mm bed vs 250×220 mm, 340 mm of Z-height vs 270 mm, and a nozzle reaching 350°C against 290°C — real headroom for ABS, ASA or fiber-filled materials.
Choose CORE One+ if…
Pick the CORE One+ if you don't want to depend on a proprietary slicer: its firmware is a Prusa-modified, fully open Marlin, compatible with any slicer that outputs Marlin-flavored G-code (Cura, ideaMaker, Simplify3D), with no lock-in to a single software ecosystem.
