This model was generated by PrintPal from the image beside it. Spin it, then switch to STL (no color) to see exactly what a single-color print 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.
SVG to STL: what actually happens
SVG is a vector format: instead of pixels it stores paths, curves and fills as XML. That makes it the cleanest possible source for a flat extrusion, because the outline is mathematically exact at any size. It also means there are no pixels to read depth from, which is why most SVG to STL tools only extrude.
This page does both. The free extruder reads your SVG's filled shapes, raises them to the height you choose, and exports an STL in millimetres without uploading anything. For a sculpted result, the AI box at the top renders the SVG in your browser at 2048 px and the generator reconstructs it as a full 3D model.

SVG extruder
Drop an SVG and get an exact, dimensioned STL in seconds. Each fill color becomes its own part, and overlapping shapes are cut so what you see is what prints.

Tips for a better STL
Convert text to outlines
Fonts are not stored as shapes in an SVG. In Illustrator use Type, Create Outlines; in Inkscape use Path, Object to Path.
Fills, not strokes
The extruder uses filled shapes. Line art drawn with strokes only needs Stroke to Path first, or the lines vanish.
Respect the nozzle
Keep features at least 1 mm wide at final size for a 0.4 mm nozzle; cookie-cutter walls about 0.8 to 1.2 mm.
Several colors?
An STL is one color. Export a 3MF with one part per color for AMS or MMU printing.
Which kind of STL do you need?
Five different things are sold as “image to 3D”. Pick the one that matches what you want to hold in your hand.
| AI reconstruction | Heightmap relief | Extrusion | Photogrammetry | |
|---|---|---|---|---|
| Full 3D object from one image | Yes | No, flat panel | No, flat profile | No, needs 30+ photos |
| Keeps exact dimensions | Proportions only | Yes | Yes, from vectors | Yes |
| Skill needed | None | None | A clean vector file | Careful shooting |
| Time | About a minute | Seconds | Seconds | Hours |
| Color output | Yes (Pro) | Light and shadow | One color per shape | Yes |
| On PrintPal | AI generator | Lithophane, filament painter | SVG extruder | Scanning tips |
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 STL
The checklist we use before printing a generated STL.
- Import it into Bambu Studio, OrcaSlicer, PrusaSlicer or Cura and set the size in millimetres. STL has no units, so PrintPal scales tiny models up to at least 80 mm on the longest side; resize to taste.
- Lay the flattest side on the bed, or use the slicer's auto-orient.
- Turn on tree supports for overhangs steeper than about 45 degrees, such as chins, ears and arms.
- Keep walls and small features at least 0.8 mm thick (two perimeters on a 0.4 mm nozzle) so detail survives.
- Printing in resin? Hollow it with about 2 mm walls and add drain holes.
- If the slicer flags errors, run the file through the free mesh repair tool.
