Most people searching for "logo to STL" want one of three things: a flat sign or badge, which means extruding the logo; a keychain or fidget toy, which is an extrusion plus a loop or a clicker; or a 3D mascot figure, which is AI reconstruction. Each needs a different tool, and all three are on PrintPal.

With your logo as an SVG, the [extruder below](https://printpal.io/convert/logo-to-stl#extrude) gives you an exact, dimensioned STL or a multi-color 3MF in seconds. If you only have a PNG, either trace it to SVG first (Inkscape: Path, Trace Bitmap) or use the [fidget clicker maker](https://printpal.io/tools/fidget-clicker-maker), which removes the background and separates colors straight from an image.

## Ways to do it

- **Sign or badge:** Extrude the SVG with a base plate, sized in millimetres. [Extruder below](https://printpal.io/convert/logo-to-stl#extrude)
- **Keychain or clicker:** Logo, loop and an optional click mechanism, multi-color 3MF from a PNG or SVG. [Fidget clicker maker](https://printpal.io/tools/fidget-clicker-maker)
- **Text-only logo:** Wordmarks and names with real fonts, plates and mounting holes. [Name sign generator](https://printpal.io/tools/name-sign-generator)
- **3D mascot:** Turn a mascot or character logo into a full 3D figure with AI. [Start above](https://printpal.io/convert/logo-to-stl#hero-prompt-card)

## How to turn a logo into an STL

1. **Get the vector file.** Ask your designer for SVG, AI, EPS or PDF; most PDFs hold vectors you can export as SVG.
2. **Extrude it below.** Set the width, depth and an optional base plate.
3. **Download STL or 3MF.** STL for one color, 3MF for one part per color.
4. **Print.** Flat side down; no supports needed for a simple extrusion.

## Things to know

- **Start from vectors:** A vector logo extrudes perfectly at any size. A traced PNG works, but check small letters and thin lines.
- **Thin strokes disappear:** Anything under about 1 mm wide at final size is too thin for a 0.4 mm nozzle. Scale up or thicken it.
- **Colors as parts:** Export 3MF to keep each brand color as a separate part for AMS or MMU printing.
- **Use logos you own:** Printing a company's logo for yourself is one thing; selling it needs the trademark owner's permission.

## STL at a glance (Stereolithography (Standard Triangle Language))

- **Stores:** Triangle geometry only
- **Color:** No
- **Units:** None; slicers assume millimetres
- **Size (our 1M-triangle test):** 49.9 MB binary, 303 MB ASCII
- **Opens in:** Every slicer, CAD tool and Blender
- **PrintPal plan:** Free and up

### After you download the 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](https://printpal.io/tools/mesh-repair).

## 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 do I turn a PNG logo into an STL?

Trace it to SVG (Inkscape: Path, Trace Bitmap, or any online tracer), then extrude it here. Or use the [fidget clicker maker](https://printpal.io/tools/fidget-clicker-maker), which takes a PNG directly and separates its colors.

### Can I make a multi-color logo print?

Yes. Export a 3MF from the extruder: each fill color becomes its own part. Assign a filament to each in Bambu Studio, OrcaSlicer or PrusaSlicer.

### How thick should a 3D printed logo be?

For a wall sign, a 2 mm base with letters raised 1.5 to 3 mm reads well. Keychains are usually 3 to 4 mm thick in total.

### Is it free?

The extruder is free with no account. AI mascot generation has a free plan with 10 generations a month.

### Can AI turn my mascot logo into a 3D figure?

Yes. Drop the logo into the AI box at the top. Characters and mascots convert well; text and abstract marks are better extruded.

### 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.
