How to Turn a Logo Into a 3D Model or Printed Sign

A 3D logo works as a physical desk sign, a shop-window plaque, a fridge magnet, or a hero graphic on a website. Which route to take depends on the logo and the destination.

Route 1: Relief (fastest, always printable)

A relief turns brightness into height, so dark areas of the logo rise and light areas stay flat (or the other way round). Our free image to STL tool does this in your browser, and the logo never leaves your computer. The result is a solid, watertight plaque, 100 mm wide, ready to slice.

• Best for: flat logos, badges, name plates and anything you want printed today.
• Tip: use a high-contrast, single-colour version of the logo. Gradients become slopes.

Route 2: Extruded vector (crisp edges)

For sharp, straight-walled lettering, trace the logo to SVG with our image to SVG converter (or use the original vector file, if you have one). Then:

1. In Blender: File → Import → Scalable Vector Graphics.
2. Select the curves and set an Extrude value under Object Data → Geometry.
3. Convert to mesh (Object → Convert → Mesh) and add a backing plate if the letters need to hold together.
4. Export STL for printing, or GLB for the web.

Recent versions of several slicers, including PrusaSlicer and Bambu Studio, can also import an SVG and extrude it directly.

Route 3: A full 3D render for screens

For a glossy, bevelled logo spinning on a website, extrude as in route 2, add a bevel (Object Data → Geometry → Bevel), and give it a metallic PBR material. Export as GLB and embed it (see 3D models on the web).

Printing a two-colour sign

The simplest method: print the base plate in one colour and pause the print (a "colour change" at a layer height, set in your slicer) where the raised logo begins. Swap filament and continue. No multi-material printer needed.

A quick word on trademarks

Print your own logo or one you have permission to use. Making and selling signs of other companies' logos is trademark infringement in most places.
