How to convert a logo to a 3D printable STL

  1. Choose your image. Drop in a PNG, JPG or WebP. For logos, a transparent PNG gives a clean cut-out shape.
  2. Pick the type. Relief for signs and coasters, lithophane for backlit photos, stamp for ink, clay or soap (mirrored for you).
  3. Set the shape and size. Rectangle, circle, heart or the logo's own outline, and the width in millimetres.
  4. Tune the height. Set the base, relief height, smoothing and contrast. Watch the 3D preview update as you go.
  5. Download the STL. Download a closed, correctly sized mesh that slices without repairs.
