Your STL, 3MF, OBJ, PLY, GLB or FBX model painted with brushes, fills and smart paint, with pictures, text and textures projected flat, wrapped round or tiled — reduced to the colours you can print and saved as a painted 3MF that PrusaSlicer, Bambu Studio and Orca open with the colours in place.

How to use it

  1. Import a model (colours in 3MF, PLY, GLB and FBX files are kept).
  2. Paint with the brush, fill or smart paint; use the mask to protect areas.
  3. Add a picture, text or texture layer and place it on the model (flat, wrapped round or tiled).
  4. Choose how many print colours, check As printed, and match them to your filaments.
  5. Use Refine detail for sharper pictures, then export the painted 3MF.

What you can do

Wrap pictures

Wrap a logo round a cup or planter, or project it flat onto any side.

Print colours

Reduce to 2–16 colours (k-means or median cut), lock colours and map them to your filaments.

Slicer-ready

One closed model with a filament on each triangle — opens painted in PrusaSlicer, Bambu Studio and Orca.

Tips

Each triangle takes one colour: refine the mesh before adding detailed pictures.

Merge tiny colour specks before printing — they can’t be printed reliably.
