# 3D Font Generator

> A 3D font generator is a tool that turns text in a chosen font into a real 3D model of the letters, ready to print or use in 3D apps. Kenerate's free generator runs in your browser with your own TTF or OTF font or 18 bundled ones, and downloads STL, 3MF, OBJ or GLB.

## Key facts
- Price: Free, no account
- Fonts: Your TTF/OTF, or 18 Google Fonts (OFL / Apache 2.0)
- Styles: Bold sans, slab, condensed, rounded, cartoon, comic, script, brush, marker, display serif, retro, futuristic, military, stencil, pixel
- Size: 5–120 mm, depth 0.6–40 mm, bevel 0–2 mm
- Output: STL, 3MF, OBJ, GLB; A–Z + 0–9 ZIP
- Privacy: Font files are read locally — never uploaded
- A 3D-looking font file: A TTF/OTF with shading drawn into each letter. It's still flat — you type with it in Word or Canva. Not what this tool makes.
- A 3D text picture: A rendered image of text with depth and lighting. You can get one here with a PNG screenshot.
- A 3D font model: Real geometry for each letter — printable as STL or 3MF, importable as GLB or OBJ. This is what the generator makes.
- Bring your own font: Brand fonts, purchased fonts, non-Latin scripts — upload the file and it's used on your device only.
- Parse: The TTF/OTF is read with the opentype parser into glyph outlines.
- Convert: Outlines become shapes with holes, scaled so the font's em size equals your letter size.
- Extrude: Shapes are extruded to your depth with optional rounded edges.
- Export: Download a word, or every letter separately.
- 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.
- 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.
- OBJ (Wavefront OBJ): Plain-text mesh; by Wavefront Technologies, 1980s. Holds: Vertices, faces, UVs and normals, Materials via a separate .mtl file. Lacks: Animation and rigs, Embedded textures. Best for: Moving static meshes between 3D apps. Opens in: Blender, Maya, 3ds Max, ZBrush, most slicers.

## Steps
1. Pick or upload a font — Choose one of 18 styles, or “Use your own .ttf / .otf”.
2. Type text — A word, a name, or just the letters you need.
3. Size and depth — Set the letter size and thickness in mm, plus rounded edges.
4. Download — STL / 3MF to print, GLB / OBJ for 3D apps, or the A–Z ZIP.

## In depth

### Fonts are already vector shapes
TrueType and OpenType fonts describe each glyph as closed curves, so turning them into 3D is a direct extrusion — no tracing, no quality loss at any size [10].

### Which fonts print well
Heavy strokes and open counters print best. Hairline serifs and fine scripts fall below the roughly 0.9 mm minimum stroke of a 0.4 mm nozzle at small sizes [11] — scale them up or choose a bolder weight.

### Licences
Fonts are software with licences. The SIL Open Font License used by most Google Fonts permits embedding and use in products [19]; commercial fonts vary, so check before selling prints.

## FAQ
Q: What is a 3D font?
A: Usually one of three things: a flat font drawn to look 3D, a 3D text image, or a 3D model of letters. This generator makes 3D models from any font.

Q: Can I use my own font?
A: Yes — upload a .ttf or .otf file. It's read in your browser and never uploaded.

Q: Why do some fonts look wrong?
A: Some fonts have overlapping or open contours. Most slicers merge overlaps automatically; if a letter looks broken, try another font or a different weight.

Q: Do script fonts work?
A: Yes. Connected scripts like Pacifico or Lobster print as one piece. Very fine scripts (like Great Vibes) need larger sizes to print.

Q: Does it support non-Latin scripts?
A: If the font includes the characters, yes. Upload a font that covers your script.

Q: Can I sell prints made with these fonts?
A: The bundled fonts are OFL or Apache 2.0, which allow that. For your own fonts, check the licence.

Q: Is this 3D font generator online and free?
A: Yes. It runs online in your browser, free with no account, and your font files never leave your device.
