Bambu Lab H2C vs Prusa Research CORE One+
Technical comparison · Fused filament fabrication (FFF/FDM)
Anyone printing water-soluble supports or parts that combine two filaments in the same layer should look at the H2C, the only one of the two with independent dual extrusion; anyone wanting to stick with fully open firmware and no proprietary software lock-in, at a much lower cost, should go for the CORE One+.

| Software notes | The printer is operated through Bambu Studio, Bambu Lab's open-source slicer based on PrusaSlicer, available for Windows, macOS, and Linux. Remote control is available via the Bambu Handy app or Bambu Suite. The machine includes a 5" color touchscreen for local operation and connects over dual-band Wi-Fi. The firmware is proprietary; Klipper is not natively supported. | 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
- Extrusion: the H2C has two independent extruders, useful for soluble supports or two materials in the same layer; the CORE One+ has one.
- Build area: the H2C offers 330×320 mm against 250×220 mm — room for larger parts.
- Firmware: the CORE One+ runs Prusa-modified Marlin, fully open with no proprietary lock-in; the H2C depends on Bambu Studio.
- Price: the CORE One+ costs about €1,050 less.
Which one to choose
Choose H2C if…
Anyone who often prints soluble supports (PVA, HIPS) alongside the main part, or wants more colors in a single pass, benefits from the H2C's independent dual extrusion and the AMS system reaching up to 24 colors, plus a larger build area (330×320 mm against 250×220 mm). The trade-off is a much higher upfront cost.
Choose CORE One+ if…
Anyone who wants fully open firmware — Prusa-modified Marlin, with no lock-in to proprietary software or protocols — and doesn't need a second extruder should pick the CORE One+, which costs about half the H2C. The trade-off is a smaller build area and no independent dual-material extrusion.
