Bambu Lab P1S vs Prusa Research CORE One+
Technical comparison · Fused filament fabrication (FFF/FDM)
Two enclosed CoreXY printers with similar build volume: what changes is the price, a gap of about 750 €, and how tied you are to one piece of software. The CORE One+ runs open Marlin firmware and accepts any slicer that outputs Marlin G-code; the P1S works best with Bambu Studio or OrcaSlicer.

| Software notes | 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. | 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
- Price → about 449 € against 1199 €: the CORE One+ costs about 750 € more.
- Colors → 16 against 5, both with an add-on: the P1S handles prints with many more colors.
- Build area → 256 × 256 mm against 250 × 220 mm: the P1S has more bed surface, the CORE One+ 14 mm more height (270 against 256).
- Firmware → Bambu Studio, with some functions tied to an account, against open Marlin: on the CORE One+ there is no lock-in to proprietary software.
Which one to choose
Choose P1S if…
Multicolor prints: up to 16 colors with the dedicated add-on, against 5 on the other. You spend about 450 € instead of 1200 €. The trade-off: some functions, such as remote timelapses and OTA updates, need a Bambu account, and the bed tops out at 100 °C.
Choose CORE One+ if…
A bed up to 120 °C, 270 mm of usable height and Prusa's modified Marlin firmware, with no lock-in to proprietary software or protocols: it works with Cura, ideaMaker or Simplify3D. You pay about 750 € more, and the bed is 250 × 220 mm against 256 × 256.
