| Software notes | Artillery OS, a Klipper-based system. Compatible with standard slicers like Cura, PrusaSlicer and OrcaSlicer via G-code. Supports Wi-Fi transfer, SD card and touchscreen control. Compared to closed platforms, it allows advanced adjustment of printing parameters, but lacks a native cloud ecosystem and requires manual slicer configuration. | 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 Artillery M1 Pro S1 if…
you value price, closed chamber and max print speed. «A closed chamber reduces thermal gradients around the part being built, limiting warping and cracking caused by rapid cooling in high-shrinkage materials such as ABS, ASA, and PC. It also shields the mechanism from drafts and airborne particles. A closed chamber is effectively necessary for technical materials; for PLA and PETG it is an advantage, not a requirement.»
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.»
