# Bas-Relief Generator — Photo to 3D Relief STL

Canonical page: https://imageto3dprint.com/bas-relief-generator

Generate a brightness-based 3D relief from a photo. Control depth, smoothing, base thickness, and dimensions, then download STL, 3MF, or OBJ.

Bring light and shadow into a new dimension. Turn image tones into a shallow surface with a solid backing.

This generator maps image brightness to surface height above a flat base. It creates a shallow, closed relief mesh for printing. It does not estimate anatomical depth, so shadows and highlights become geometry. Use a prepared depth map when you need a specific sculpted shape.

## Choose the right source

Use a photograph for a tonal surface or a grayscale depth map for more deliberate control over its shape.

## Shape the impression

Adjust the depth range, smoothing, and base thickness. Invert the image to reverse which tones are raised.

## Inspect before printing

Rotate the actual generated relief and inspect its geometry report before downloading STL, 3MF, or OBJ.

## Tips

- Choose a clear portrait with an uncluttered background.
- Avoid strong shadows that hide important facial features.
- Think about how much depth suits your intended display.

## Frequently asked questions

### Is a bas-relief a complete 3D model?

The output is a closed mesh with a shallow height surface and a flat back. It does not reconstruct a subject from every angle.

### Will this work for CNC carving?

The mesh can be a starting point, but tooling, workholding, and toolpaths require separate checks in CAM software. The download contains geometry, not CNC instructions.
