| Software notes | 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 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 CORE One+ if…
you value closed chamber, maximum colors and max bed temperature. «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 price, work area and multi-extruder. «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.»
