Bambu Lab H2S vs Prusa Research CORE One+ kit
Technical comparison · Fused filament fabrication (FFF/FDM)
The H2S and the CORE One+ kit target makers who already print regularly, but start from opposite premises: the Prusa kit ships unassembled and costs less, the H2S arrives ready to use with a bigger bed and a higher declared speed.

| 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. | Prusa firmware based on Marlin, fully open source, with built-in input shaper for faster and cleaner prints. Official slicer: PrusaSlicer (free, optimized profiles), compatible with Cura and Simplify3D. Control via USB, Ethernet or Wi-Fi with Prusa Connect (optional). No filament DRM: full freedom to use third-party materials. |
The differences that matter
- Declared print speed: up to 1000 mm/s on the H2S versus 200 mm/s on the CORE One+ kit — batch jobs take less total time on the H2S.
- Work area and Z-height: H2S 340×320 mm and 340 mm, versus 250×220 mm and 270 mm on the kit.
- Price: the kit costs €151 less than the H2S, but requires user assembly.
- Firmware: the CORE One+ kit runs open-source Marlin with no filament DRM; the H2S performs best inside Bambu Studio.
Which one to choose
Choose H2S if…
The H2S has a declared print speed of up to 1000 mm/s, against the CORE One+ kit's 200 mm/s, and a 340×320 mm bed versus 250×220 mm — useful for large or batch parts where total print time matters. Its nozzle reaches up to 350°C against 290°C. It costs €151 more than the kit and arrives already assembled.
Choose CORE One+ kit if…
The CORE One+ kit costs €1049, €151 less than the H2S, but the user has to assemble it. Its Marlin firmware is fully open source with no filament DRM: no restrictions on third-party materials. The smaller bed (250×220 mm) and lower declared speed (200 mm/s) are the trade-off.
