Free local 3D tool
Make a flat lithophane from your photo. Choose its width and thickness, preview the panel, then download STL. Dark areas are thicker so the picture appears when lit from behind.
Add a photo or try the sample to preview its thickness.
80 mm wide · 0.8–3 mm thickness range · 122 × 144 samples
This flat panel was made from the photo shown here. Image brightness controls its thickness; the example has not been physically printed.
Choose a PNG, JPG or WebP up to 8 MB. Crop around the subject before adding it, then adjust contrast and smoothing for a readable picture.
Start with 0.8 mm minimum and 3 mm maximum as a test range. Dark pixels are thicker by default. Transparent pixels use the minimum thickness; use an opaque photo for predictable tones.
The STL is flat: X/Y form the picture and Z is thickness. Set orientation, solid infill and adhesion in your slicer, then test a small panel with your filament and light.
A rectangular, flat-backed panel whose thickness follows image brightness. It is a photo panel, rather than a full 3D reconstruction. This 3D lithophane generator does not add curved panels, frames, stands or lamp enclosures.
Thicker material transmits less light, creating the dark parts of a backlit picture. The default mapping runs from 0.8 mm at white to 3 mm at black. Turn off Dark pixels are thicker for a negative image.
No. The example is a digital transmission illustration from the same thickness data, not a physical print or a calibrated material simulation. Actual contrast depends on your filament, printer settings and light source.
This tool currently exports a flat panel and samples the longest image side at up to 144 points. Curved shapes, custom frames and adjustable mesh resolution are not available here.
