Lithophane
Turn a photo into a 3D relief: print it, put a light behind it, and the image appears. Dark = thick, light = thin. Everything is generated in your browser.

Portraits and photos with good contrast work best. The image is processed locally.
Min and max thickness in mm, size, frame, and flat or curved shape — with a backlit preview.
White or natural filament, 100% infill, 0.1–0.15 mm layers, and put a light behind it.
0.6–0.8 mm in bright areas and 2.5–3.5 mm in dark ones is the sweet spot for white PLA: enough contrast without fragile zones. The tool's defaults are already in that range.
White or natural PLA, 100% infill, 0.1–0.15 mm layers, and print the lithophane vertically (on edge) so layer lines don't cross the image. Slow, but worth it.
In a lithophane, material blocks light: dark areas of the photo need MORE thickness. The tool already inverts luminance correctly — if it looks reversed, check you didn't enable manual inversion.
Portraits with even lighting and good contrast. Very dark photos, busy backgrounds or ultra-fine detail lose legibility — check the backlit preview before printing.
