Software notes Compatible with Bambu Studio (OrcaSlicer-derived) and OrcaSlicer. Supports LAN mode for cloud-free printing. Does not run native Klipper. 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 A1 mini if…

you value price.

See the A1 mini sheet →

Choose U1 3D Printer if…

you value work area, maximum z height and multi-extruder. «The Z height determines how tall a part the machine can produce in one print. Vertical objects such as vases, load-bearing structures, or casting patterns require a high Z travel. A lower value does not affect quality but forces the user to split or reorient the model. Z height should be considered alongside the XY surface to assess total usable build volume.»
