This model was generated by PrintPal from the image beside it. Spin it and compare the full-color version with the plain STL a single-color printer gets.
Input: rocket.png, 1024 pxFour flat colors on smooth toy shapes: red, cream, blue and yellow each map onto one filament for a multi-color print.

Each example is one AI-generated 1024 px PNG run through PrintPal's full-color image-to-3D at high detail, with no editing afterwards. Mesh checks were run on the raw download with trimesh. The preview is simplified to about 60,000 triangles so it loads fast; your download keeps full detail.
JPG to 3MF: what actually happens
A photo has thousands of colors and your printer has maybe four. Converting a JPG to a multi-color 3MF is mostly a color problem: after the AI reconstructs the object, its texture has to be reduced to a few filament colors without losing what makes the subject recognizable.
PrintPal's multi-color export does that reduction in your browser and lets you pin colors by tapping the model, for example clicking a dog's ear to lock its brown. If the photo does not need to be 3D, the filament painter and lithophane generator are the other great ways to print it.

- Phone and camera photos, most images on the web
- Watch out for
- Re-compressed copies from social apps (blocky artifacts)
- Background: Separated from the subject automatically; plain backgrounds work best.
- Orientation: The EXIF rotation from your phone is applied before upload.
- Compression: Heavy artifacts can read as surface bumps, so use the original file.

How to convert JPG to 3MF
-
1
Upload the photo
Strong, distinct colors and even light give the cleanest color separation.
-
2
Sign in and generate in full color
Full color is a Pro feature.
-
3
Reduce the colors
Open Multi-color export, choose 3 to 5 colors and tap the model to pin important ones.
-
4
Download the 3MF
Open in Bambu Studio or OrcaSlicer and sync with your AMS.
Tips for a better 3MF
Contrast is everything
Subjects with distinct color areas (a ginger cat, a red car) separate cleanly. Beige on beige blends into one filament.
Even light keeps colors honest
Deep shadows turn into a separate dark filament. Shoot in diffuse light so one surface stays one color.
Choose 3 to 5 colors
Enough to read as the subject, few enough to keep the print fast and low-waste.
Faces need care
Eyes and lips are small color islands. For people, the bobblehead maker and face 3D generator are tuned for it.

One model, every format
We exported the same 998,810-triangle generation to each format and measured the files.
| Format | File size | Color | Units | Typical use |
|---|---|---|---|---|
| STL (binary) | 49.9 MB | No | None (slicers assume mm) | Any slicer |
| STL (ASCII) | 303 MB | No | None | Legacy CAD; avoid |
| OBJ + MTL + texture | 84.9 MB | Texture or vertex colors | None | Blender, sculpting |
| GLB (with textures) | 40.5 MB | Yes, PBR textures | Metres | Web, AR, games |
| 3MF (zipped) | 21.0 MB | Yes, per triangle | Millimetres | Bambu Studio, OrcaSlicer, PrusaSlicer |
| PLY (binary) | 27.3 MB | Vertex colors | None | Scans, point clouds |
Same 998,810-triangle knight exported with trimesh; the GLB is the download as it came from PrintPal. The 3MF holds geometry only; a painted multi-color 3MF adds a little for the color data.
After you download the 3MF
The checklist we use before printing a generated 3MF.
- Open it in Bambu Studio or OrcaSlicer. Units travel with the file, so it loads at the right size.
- The colors in the file show up as filaments in the slicer; sync them with your AMS or pick the closest spools you own.
- Keep the prime tower on and check the purge estimate. Fewer colors means less waste and a faster print.
- Using PrusaSlicer or another slicer? Download the vertex-color OBJ from the same export, or print the STL in one color.
- Single-color 3MF only? Convert any STL free with the 3D model converter.
