Four-tool mapping
See source colors, assign T1–T4, and compare them with the filament reported by the printer before slicing.
Free · Open source · Made for U1
From model to four-color print. On iPhone.
Prepare STL and supported 3MF files, map painted colors to the Snapmaker U1’s four toolheads, slice on your phone with Kiri:Moto, preview the G-code, and send it over your local network.

Built around the U1 workflow
Keep the model, tools, and loaded filament visible as you move from import to printer.
Offline slicing
Kiri:Moto runs inside the app. Progress and errors are shown, and completed G-code can be inspected layer by layer.
Local printer view
Upload a file, check print status and history, see loaded filament, and refresh the U1 camera when the printer is reachable.
See what you are about to print
A model-first Prepare screen makes color assignments and sliced toolpaths easier to inspect.
What to expect today
Models and profiles
STL and supported 3MF geometry, parts, and painted colors work. Some creator-specific project settings and modifiers do not transfer. SnapSlice does not convert Bambu or Orca profiles to U1 profiles.
Connection
Printer features need a reachable U1, normally on the same Wi-Fi. There is no built-in remote relay, background push service, or continuous camera video.
Large files
Slicing uses the iPhone’s CPU and memory. Complex files can take longer or exceed device limits. The progress percentage is not a time prediction.
Print safety
Match each chosen tool to the loaded filament and verify material, temperature, and first layer before starting a print. Different-material support interfaces are not automatically validated.
