| 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. |

Which one to choose
Choose P1S if…
you value price, maximum colors and closed chamber. «The maximum number of colors indicates how many distinct color zones or materials can be used in one print without manual intervention. Two colors cover most practical uses, including soluble support. Higher values are useful for complex decorative models or color-coded prototypes. Each additional color increases print time due to transition purges, so the practical benefit should be weighed against the added time cost.»
Choose U1 3D Printer if…
you value multi-extruder, native klipper and work area. «A second extruder allows printing with two different materials in the same session: soluble support material for complex geometries, or a combination of rigid and flexible in the same part. It expands process capabilities but introduces calibration complexity and the risk of oozing from the idle nozzle. Most useful for work involving geometries that require supports difficult to remove manually.»
