SVG files already separate colors cleanly: every filled shape has an exact fill. That makes SVG to 3MF the most reliable route to a crisp multi-color sign, badge, keychain or coaster, far cleaner than reducing a photo's colors down to a few filaments.

The [extruder below](https://printpal.io/convert/svg-to-3mf#extrude) groups your SVG's shapes by fill color, extrudes each group, and writes a 3MF in millimetres with one part per color. Open it in Bambu Studio, OrcaSlicer or PrusaSlicer and assign a filament to each part. Want a sculpted 3D version of the artwork instead? Use the AI box at the top.

## How to convert SVG to 3MF

1. **Drop your SVG into the extruder.** Shapes are grouped by fill color automatically.
2. **Set width, depth and base.** Add a base plate for signs and coasters so the colors sit on one solid backing.
3. **Download 3MF.** One part per color, sized in millimetres. No account needed.
4. **Assign filaments.** In your slicer, give each part its own AMS or MMU slot and print.

## Things to know

- **Flatten overlaps first:** SVG paints later shapes over earlier ones; a 3MF does not. Use Pathfinder, Divide (Illustrator) or Path, Union per color (Inkscape) so shapes do not overlap.
- **Match your slot count:** One AMS unit holds four spools. Merge near-identical fills so the color count matches what you can load.
- **Use a base plate:** Thin color pieces on their own fall over. A 1.5 to 2 mm base joins them into one sturdy print.
- **Outline all text:** Live text is ignored. Convert it to paths before exporting the SVG.

## SVG at a glance (Scalable Vector Graphics)

- **Type:** Vector (XML paths and fills)
- **Transparency:** Yes
- **Typical source:** Logos, icons, Cricut and laser files, illustrations
- **Watch out for:** Live text, stroke-only lines, embedded bitmaps
- **Paths in the conversion:** Extruded exactly in the free extruder, with sizes in millimetres.
- **Fill colors in the conversion:** Grouped so each color can print as its own part.
- **For AI in the conversion:** Rendered to a 2048 px image in your browser, then reconstructed.

## 3MF at a glance (3D Manufacturing Format)

- **Stores:** Mesh, units, colors and materials, multiple objects, print settings
- **Color:** Yes, per triangle
- **Units:** Explicit (millimetres)
- **Size (our 1M-triangle test):** 21.0 MB zipped, versus 49.9 MB as STL
- **Opens in:** Bambu Studio, OrcaSlicer, PrusaSlicer, Cura, Windows 3D Builder
- **PrintPal plan:** Multi-color export on Pro; single-color 3MF free via the converter

### After you download the 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](https://printpal.io/tools/3d-model-converter).

## Same model, every format (measured)

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.

| 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 |

## Real example

The toy rocket model shown on the page was generated by PrintPal from rocket.png (1024 px). Raw output: 999,316 triangles, one watertight body with consistent winding. Web preview: 59,958 triangles, 362 KB GLB.

## FAQ

### How does each color become a separate filament?

The extruder groups shapes by their fill color and writes each group as its own object in the 3MF, with the color recorded. In the slicer you assign a filament to each part.

### Does it work with Bambu Lab AMS?

Yes. Bambu Studio and OrcaSlicer open the 3MF in millimetres with each color as a separate part. If they arrive as separate objects, select them all and use Assemble to keep them aligned.

### Why does my slicer show overlapping parts?

The SVG had shapes stacked on top of each other. Flatten the artwork so each area belongs to one color only, then export again.

### Is the SVG to 3MF extruder free?

Yes. It runs in your browser with no account and nothing uploaded.

### Can I get a 3D sculpted model in multi-color?

Yes, with the AI route: drop the SVG in the box at the top, generate in full color (Pro), then use the multi-color export to get a painted 3MF.

### How long does a conversion take?

Draft quality usually finishes in 30 to 60 seconds. Refined and Production take longer because they build more detail, and Pro generations run on a priority queue.

### Can I sell prints of the models I make?

Yes, on Pro and Studio, which include commercial rights for prints and digital files. The Free plan is for personal use. You also need the rights to the image you upload, so stick to your own photos and artwork or images you have permission to use.
