3D text is built by taking a 2D letter outline and “extruding” it — pushing every point along the outline outward to create real depth. The result is a solid mesh with a front face, a back face, and side walls that a 3D printer, game engine, or renderer can treat like any other object.

Bold, geometric fonts (like sans-serif display faces) extrude cleanly and print reliably. Thin, script, or heavily-decorated fonts can produce fragile walls that snap on the printer or dim details in the render. When in doubt, start with a bold weight and preview it live before committing.

Depth controls how far the letters push back — a shallow value reads like an embossed logo, a heavy value like a chunky title card. Bevel softens the sharp 90° seam where the face meets the side wall, catching light and making the extrusion feel physical. Small bevels (0.5–1) look best for print; larger bevels shine in renders.

Ten built-in material presets (Standard, Plastic, Metal, Glass, Neon, Rubber, Chrome, Gold, Clay, Holographic) plus procedural textures let you take the same word from clay mockup to chrome hero shot in one click. The light rotation slider swings the key light around the scene so you can find flattering, shadow-shaped angles fast.

The Text Curve control bends your line along an arc — great for badges, logos, and product art. Combined with the Wave control (a sine along the baseline), you can produce ribbon-like or hand-wave layouts without any mesh editing. Both effects are non-destructive: dial them back to zero any time.

For 3D printing, use STL or 3MF and set Real Width (mm) so the exported model matches the physical size you want on the bed. For real-time renders, games, or AR use GLB — it’s tiny and carries material data. For a stills or a logo mockup, a transparent PNG (or the WebM animation reel) is often all you need.
