Color workflow guide
How to Split a 3MF by Color
A painted 3MF can be turned into separate color parts without uploading the model. Use this guide when you want to print each color separately and assemble the result.
A five-step workflow
- 1
Open the painted 3MF and confirm the filament colors appear in the preview.
- 2
Click one color region and choose Split off or press Space.
- 3
Repeat until the required color regions are separate parts.
- 4
Use Press in for thin painted text or details that would not make a solid piece.
- 5
Preview, add connectors if needed, and export the format that matches your slicer.
Prepare the painted file
Paint the model in Bambu Studio, OrcaSlicer, or PrusaSlicer before opening it. A plain STL has no painted regions, so it cannot provide the same color boundaries. If colors are missing, check the original project and export the painted 3MF again.
Split each color carefully
Click a visible region rather than a cut face. The tool keeps the remaining painted colors in the rest of the model, so you can work one color at a time. Inspect small islands and thin details because they may be merged, pressed in, or left in place.
Choose an export
Plain 3MF provides one object per part, STL gives you a separate mesh per part, and the Bambu Studio project keeps filament assignments and plate layout when the current Pro access rules allow that download.
Print and assemble
Slice the pieces with your own profiles, print a clearance test if you add connectors, and dry-fit the parts before glue. The tool prepares geometry; it does not choose material, support, or finishing settings.
