# 3D Logo Maker

> A 3D logo maker is a tool that turns a flat logo into a 3D model. Kenerate's free maker works in your browser from an SVG or a PNG: set the width and depth in millimetres, add a plate or keychain tab, and download STL, 3MF or GLB. Your logo is never uploaded.

## Key facts
- Price: Free, no account
- Input: SVG (recommended) or PNG / JPG
- Depth: 0.4–30 mm, plus extra height per colour (SVG)
- Base: None, plate or keychain
- Output: STL, 3MF, OBJ to print · GLB (web, AR, game engines) · PNG screenshot
- Privacy: Processed in your browser — no upload
- A logo you can hold: Signs, desk plaques, badges, magnets and keychains — STL or 3MF in real millimetres.
- A logo for screens: Download a GLB to spin it on a website with model-viewer or drop it into Blender, Unity or a slide deck. Or save a PNG screenshot — turn the grid off for a transparent background.
- SVG or PNG: SVG gives perfect curves and colour layers. A transparent PNG works too: its opaque area becomes the shape.
- Multi-colour printing: Raise each SVG colour a little so a filament change at each height prints your brand colours.
- Read the logo: SVG paths are grouped by colour; PNG pixels are split by transparency or brightness.
- Scale: The logo is centred and sized to your width in millimetres.
- Extrude: Each shape is raised to its depth, optionally on a plate or keychain tab.
- Export: STL / 3MF for printing, GLB for screens.
- STL (Stereolithography): Triangle mesh (binary or ASCII); by 3D Systems, 1987. Holds: Triangle surfaces, Facet normals. Lacks: Colour and textures, Units, Materials. Best for: 3D printing — every slicer opens it. Opens in: Cura, PrusaSlicer, Bambu Studio, OrcaSlicer, Blender.
- 3MF (3D Manufacturing Format): ZIP package with XML; by 3MF Consortium, 2015. Holds: Meshes with units (millimetres), Colours and materials, Several objects and build plates. Lacks: Animation. Best for: Modern 3D printing and multi-colour prints. Opens in: Bambu Studio, PrusaSlicer, OrcaSlicer, Cura, Windows 3D Builder.
- GLB (glTF 2.0 Binary): Single-file scene with PBR materials; by Khronos Group, 2017 (glTF 2.0). Holds: Meshes and PBR materials, Textures in the same file, Animation and skins. Lacks: Units beyond metres, CAD precision. Best for: Web, AR and real-time apps — the “JPEG of 3D”. Opens in: Browsers (three.js, model-viewer), Blender, Unity, Unreal, Godot.

## Steps
1. Add your logo — Choose SVG or PNG / JPG and drop the file, or try the sample.
2. Set size and depth — Pick the width and how deep the logo should be.
3. Add a base — Choose a plate for a sign or a keychain tab.
4. Download — STL or 3MF to print; GLB for web and 3D apps.

## In depth

### Vector first
A logo saved as SVG keeps exact curves and separate colour shapes, which translate directly into smooth extrusions and colour layers. A PNG has to be traced from pixels, so its edges follow the pixel grid.

### Designing for print
Fine lines, small text and hairline gaps don't survive at small sizes: walls under about 0.45 mm can't print with a 0.4 mm nozzle, and 0.9 mm is a safer minimum [11]. Logos with separate pieces (like a dot over an i) need a backing plate to stay together.

### Designing for screens
For websites and AR, GLB is the standard format [4][8]. Keep depth modest — about 5–10% of the width usually looks best — and add materials in a viewer or editor.

## FAQ
Q: How do I make my logo 3D for free?
A: Drop your logo file into the tool above, set its size and depth, and download. It's free and runs in your browser.

Q: Should I use SVG or PNG?
A: SVG if you have it — curves stay smooth and each colour can be its own layer. A transparent PNG is the next best thing.

Q: Can I 3D print a logo?
A: Yes. Download STL or 3MF. Keep the thinnest parts above about 0.9 mm and add a plate if the logo has separate pieces.

Q: Can I use the 3D logo on my website?
A: Download the GLB and show it with a 3D web viewer, or take a PNG screenshot for a static image.

Q: Does it add materials like gold or chrome?
A: No — it makes the geometry. Add materials in Blender or your web viewer, or print in a silk or metallic filament.

Q: Can I use the result commercially?
A: The model is made from your logo, so you can use it as you're allowed to use the logo itself.

Q: Is my logo uploaded?
A: No. It's processed on your device.
