| 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. | The primary software is Snapmaker Orca, an optimized version of the popular OrcaSlicer, which provides native management of the four toolheads and factory-calibrated material profiles. The printer can also be seamlessly managed via the Snapmaker mobile app for remote monitoring, taking advantage of the built-in 1080p camera. The internal firmware is built on Klipper, Moonraker, and Fluidd, which Snapmaker has made open-source, allowing experienced users to customize the machine and integrate it into complex workflows. |

- Price: P1S 449 € vs U1 3D Printer 849 € — P1S wins (+89%)
- Max colors: P1S 16 vs U1 3D Printer 4 — P1S wins (+300%)
- Enclosed chamber: P1S yes, U1 3D Printer no
- Multi-extruder: U1 3D Printer yes, P1S no
- Native Klipper: U1 3D Printer yes, P1S no
Which one to choose
Choose P1S if…
Choosing the Bambu Lab P1S is recommended for those who need an enclosed machine to print technical materials like ABS or ASA and desire an affordable multicolor printing system, accepting the use of an external accessory for filament management.
Choose U1 3D Printer if…
Choosing the Snapmaker U1 is preferable for those seeking a native Klipper system with integrated four-head multi-extruder management and open-source software, prioritizing firmware customization ease and integration into advanced workflows without additional color accessories, despite a higher initial investment and an open structure not suitable for materials sensitive to thermal fluctuations without external modifications to the frame or printing environment. The machine also offers an integrated 1080p camera for native remote monitoring and a slightly larger build volume compared to the P1S. The choice between the two machines mainly comes down to the preference between a closed solution optimized for multicolor (P1S) or an open platform based on Klipper with native multi-extrusion (U1). The price difference of approximately 350-450 euros reflects the different hardware integration philosophy and the presence of components like the high-resolution camera and the multi-extruder system integrated into the U1. The P1S remains the most efficient choice for those who mainly print technical materials in a closed chamber, while the U1 offers superior software control thanks to the native Klipper/Fluidd architecture and simplified management of four colors without additional external bulk.
