Printing guide
Your filaments.
Your little masterpiece.
Begin with the colours in your printer, then inspect the whole model before creating a print file.
Colour selection, 3D previews and model preparation stay free. Creating and sharing print files uses the same one-time €1.99 export purchase as other exports. The App Store displays your regional price.
Tell the app what is loaded
Open Colours & printing. Choose your printer and match each slot to its actual filament colour before continuing. Choose four filament slots for Snapmaker U1, or five for Prusa XL 5T. These targets organise your colours; select and verify the actual printer, nozzle and material profiles later in your desktop slicer.
These choices are saved for that printer. Use Change loaded filaments whenever you change a spool.
Review colours in 3D
Switch between Print colours and Original scan. Drag to rotate, pinch to zoom, and inspect every side.
People colours groups suggested body and clothing regions. Select a part, inspect it close up and choose a filament or blend. Refine or touch up a boundary where the suggestion misses a beard, cuff, shoulder or clothing edge. Suggested regions are editable, not guaranteed segmentation.
Full Spectrum offers predicted colours made from pairs of your loaded filaments. The 3MF records pair-blend recipes for interleaved layers. A compatible Snapmaker Orca desktop version must support these recipes to produce the intended alternation; ordinary colour import alone is not enough. This does not mix pigments inside a nozzle. The preview is an estimate. Material opacity, layer height, lighting and the actual spools influence the physical result.
Set the size and flatten the feet
Choose the miniature’s final print height. This is separate from the scan’s real-world size.
Flatten feet trims uneven soles, closes the new cut surfaces and places them on the print bed. Start with a small trim and inspect the result. The app reports contact areas and keeps the selected final height; your original scan is preserved.
If a cut cannot be closed reliably, choose another trim. A flat base does not repair other holes or guarantee that a tall model is stable.
Choose a layer height
The U1 project options include 0.08 mm, 0.10 mm and 0.20 mm. Your choice is saved in the exported project. Check the colour cross-section alongside the full 3D model, then confirm the layer height against your printer, nozzle and material profile in the desktop slicer. The cross-section is not a preview of walls, infill, supports or printer movements.
Export, then slice on a computer
Export colour 3MF creates a project with the same colour assignments shown in the preview, your loaded-filament colours and Full Spectrum recipes. Share it to a Mac or PC and open it in a compatible desktop slicer. For U1 Full Spectrum recipes, use a Snapmaker Orca version that supports the exported virtual blends; generic 3MF viewers may ignore them.
Select the matching printer, nozzle and material profiles in that slicer. Confirm the filament-slot mapping, layer height and blend support, then generate and inspect the toolpaths. Check supports, tool changes and all printer settings before transferring G-code to the matching printer. 3Dmee does not generate G-code on the iPhone or automatically send print jobs.
Try a small print with your actual filaments before committing to a large miniature. An exported colour project is different from reviewed toolpaths or a validated physical print. The desktop slicer and printer must support your chosen materials and blend workflow.
